TMP Goals

The primary purpose of the TMP is to address the construction-related traffic impacts of the

OR8: Corridor Improvements Project in a cost-effective and timely manner. It also serves to

identify means and methods to minimize public inconvenience due to constructions activities.

This Traffic Management Plan (TMP) document will facilitate the development team’s

understanding of how traffic is planned to be managed and why these decisions were made

during project development along with details behind the Traffic Control Plans (TCP) and other

measures that will be put in place during construction to minimize disruptions to traffic without

compromising public and work zone safety. This Transportation Management Plan is a living

document, subjected to additions and modifications throughout the life of the project.

Goals of this Project-Level TMP include the following:

• Describe the project construction footprint.

• Aid in creating a project development and decision-making environment that looks at

options available to limit and mitigate anticipated construction impacts.

• Communicate what elements will be included in the project to mitigate for anticipated

disruptions to travelers and freight without compromising public or worker safety.

Project Background

The scope of the project includes removal and replacement of the existing traffic signal and

pedestrian flasher systems at the following locations:

• OR8 (Baseline Street) at OR 219 (S 1st Avenue) – traffic signal control intersection.

• OR8 (Oak Street) at OR219 (S 1st Avenue) – traffic signal control intersection.

• OR8 between SE 44th Avenue and SE 45th Avenue – pedestrian crossing with pedestrian

activated flashing beacon.

Project Area Boundaries

All project areas are within the City of Hillsboro boundaries and within Oregon Department of

Transportation (ODOT) Region 1 jurisdiction. Figures 1 and 2 show the project areas.

Proposed Improvements

The main improvements to be incorporated at each location are as follows:

• OR8 (Baseline Street) at OR219 (S 1st Avenue), the proposed improvement at this

location include:

o Installation of a new traffic signal system and illumination system. o Updated intersection signing.

o New curb ramps to meet current ADA standards.

Project Area Characteristics

This section includes a summary of existing transportation conditions within the project areas

relevant to this TMP, including traffic and roadway characteristics and location of other

construction projects.

Traffic Characteristics

Annual average daily traffic (AADT) volumes along OR8 and OR219 near the project sites were

researched to better understand the volume of vehicles that would need to be accommodated

during construction of each site. AADT’s are summarized in Table 1.

Location of Other Construction Projects

To minimize construction impacts for motorists, other planned projects near the vicinity of these

projects have been identified. The following are known projects that will occur near or at the

same location with the proposed projects1:

K18794 - OR8: SW 10th – SW 110th

- Project Description: safety upgrades to install larger signal heads, reflective

backboards, pedestrian countdown signals and left turn phasing where feasible.

Proposed Construction Date: 2019

Factors Impacting Construction Staging

This section summarizes the factors that will impact construction staging that includes: project

schedule, proposed improvements and impacts to traffic flow, alternate routes, existing vehicle

restrictions, Work Zone Lane Closure Restrictions, environmental issues, seasonal restrictions,

and construction noise regulations.

Project Schedule

The project is tentatively scheduled to bid in February 2019. A detailed construction schedule

has been created as part of the project development process and will be available from the

agency. Refinements to the schedule will continue to evolve during the design process.

Additional schedule modifications are expected once a contractor has been selected.

Proposed Improvements and Potential Impacts to Traffic Flow

This project includes the proposed improvements listed in Section 2.2. Much of the construction

will be completed using single lane closures. However, short-term (20-minute) full closures may

be utilized to facilitate mast arm removal and installation at the OR8 (Baseline Street) / OR 219

(S 1st Street) and OR8 (Oak Street) / OR 219 (S 1st Street) intersections. They will also be

necessary at the OR8 pedestrian crossing between SE 44th Avenue and SE 45th Avenue to

facilitate the removal of the overhead pedestrian activated flashing beacons and span wire.

These closures will be during off peak periods at night. Alternatively, traffic control measures for

this work may be multi-lane closures with flagging during off peak hours.

Existing Vehicle Restrictions

Based on review of the current ODOT Motor Carrier Transportation (MCTD) Road and Bridge

Restrictions website2, no roadways have existing weight, height, or width restrictions for vehicles

within the project limit. The website will be periodically reviewed prior to bid letting. When

• Oregon International Air Show - TBD 2019 Add the following subsection: 00220.40(f) Limited Duration Road Closure - The Contractor will be permitted to close all Traffic Lanes for periods not to exceed 20 minutes in duration during the signal pole mast arm installation or removal of the overhead span wire over the Traffic Lanes. This work will only be permitted at night between the hours of 10:00 p.m. and 5:00 a.m., Monday through Sunday, on the Tualatin-Valley Highway (OR8) at a single intersection or section at one time as shown below: (a) For removing or erecting signal pole mast arm

• Oak Street Eastbound (OR8) at OR219 (S 1st Avenue)

• Baseline Road Westbound (OR8) at OR219 (S 1st Avenue)

(b) For removing the overhead span wire

• OR8 between SE 44th and SE 45th Avenues Succeeding roadway closures will not be allowed until traffic clears from a preceding closure.

Seasonal Restrictions

There are no weather related seasonal restrictions for upgrading the traffic signal systems and

illumination systems at the project sites. Any cast in-place concrete related works such as the

construction of ADA approved curb ramps, sign support footings (If there will be any new

Breakaway Posts Anchored in Ground), and constructing the cast in place concrete foundation

when installing the signal pole support structure that carries the rectangular rapid flashing

beacon would be restricted during below freezing temperatures. Casting concrete during

freezing or below freezing temperature can cause the fresh concrete to freeze before it settles

and prevent it from attaining its desired strength.

Alternate Routes

Drivers who are familiar with the area can choose alternative routes to avoid each of the project

sites. Full road closures other than short-term (20-minute) closures during off-peak hours are

not anticipated at any of the project sites.

Construction Noise Regulations

The basic requirements of applicable noise regulations for City of Hillsboro are listed below:

Unless authorized by the manager, it is unlawful for any person to produce or allow to be

produced, with or from a sound-producing source, sound that:

A. Exceeds:

1. 50 decibels A-weighting (dBA) at any time between 9 p.m. and 6 a.m. the following day, or

2. 60 dBA at any time between 6 a.m. and 9 p.m.; or


May 4, 2018


Page | 12

B. Is plainly audible at any time between 9 p.m. and 6 a.m. the following day:

1. Within a noise-sensitive building which is not the source of sound, or 2. On a public right-of-way from a distance of at least 100 feet from the source of the

sound.

ODOT’s 2011 Noise Manual has methods and procedures for abatements of highway traffic

noise and construction noise. The construction noise abatement section of the manual lists

methods and procedures that are typically implemented to limit the noise levels when

construction takes place near noise sensitive land uses. Section 2, Section 8, Appendix B and

Appendix H of the ODOT Noise Manual describes the standards and procedures for noise

abatement, construction equipment noise levels and mitigation for construction noise impacts.

Potential Mobility Issues

This section includes a discussion of traffic mobility issues during construction, input from the

public and stakeholders, agency coordination, holidays and special events, and consideration of

oversized vehicles.

Traffic Mobility during Construction

Traffic mobility for general traffic and annually permitted freight traffic will be maintained at all

times. Emergency vehicles will be permitted through the work zone at all times during the

construction.

For the construction phases at the intersections of OR8 (Baseline Street) / OR219 (S 1st

Avenue) and OR8 (Oak Street) / OR219 (S 1st Avenue) single lane closures will be used during

most off-peak hours.

At OR8 between SE 44th Avenue and SE 45th Avenue, single lane closures and short term full

roadway closures (20-minutes) are considered. Short-term full closures of the roadway will be

necessary for the removal of the overhead pedestrian activated flashing beacon and associated

span wire.

Input from the Public and Stakeholders

The scope of this project, as it affects the public, is guided primarily by technical factors and

ODOT policy. The primary goals of the communication effort for this project are to inform project

stakeholders, including affected property owners, tenants, and the adjacent community, of

construction activities and to gather feedback on factors that will affect them. The major

communication elements planned for this project will be determined by ODOT Region 1 staff.

Agency Coordination

Local agencies and other departments within ODOT need to be contacted and notified before

the start of project construction to coordinate any unknown issues that may not have been

identified during the design phase. Particularly close coordination with local agencies (City of

Hillsboro and Washington County) is necessary for the planning and use of the need for


May 4, 2018


Page | 13

unforeseen detour routes and coordinating with other known projects in the area near the

project area (see Section 4).

Consideration of Over-Sized Vehicles

As mentioned on Section 3.2. OR8 within the project vicinity is a federally designated truck route

and is part of the National Highway System. It is essential that any temporary lane restrictions

can accommodate large trucks during construction to minimize impact to the timely and

dependable movement of goods.

When a project restricts the width, length, height, or weight of vehicles through a work zone or

detours trucks around a work zone, the MCTD must be notified by using the web based

electronic version of the "Highway Restriction Notice-Size and/or Weight" form (Form No. 734-

2357) at least 28 calendar days before the restriction or detour takes effect. As soon as the

restriction is lifted, notification must be sent to the same individuals on a revised copy of the

original Form #734-2357 so this information can be relayed to all affected parties. No such

restrictions are anticipated for either project site.

Traffic Management and Operation Strategies

To help meet the performance goals for congestion management and promote work zone

safety, several types of traffic management strategies were examined for implementation. A

range of common traffic management strategies is available for consideration on this project.

The strategies selected are described below. It should be recognized that before selecting a

strategy for application, an evaluation of the benefits provided versus the cost to implement

should be conducted. Project budgets may determine which strategies can be implemented.

ODOT’s Decision Tree Matrix (Form #734-5042) has been assembled to document traffic

management and operational strategies and the reasoning behind the decision for their use on

the project. The Decision Tree Matrix has been included in Appendix A.

Public Information and Outreach Strategies

Making the public aware of the potential delays incurred while traveling through the project area

or detour routes may encourage motorists to use alternate routes or plan trips to avoid peak

construction periods. This will help to manage congestion within the project area. Therefore,

public information and outreach is beneficial for maintaining public support for projects, as well

as for encouraging changes in travel behavior during construction.

Motorist Information/ITS Strategies

Providing motorists with real-time information helps notify drivers of upcoming work zones and

may alleviate congestion and delay. Existing Intelligent Transportation Systems (ITS) and other

strategies may be used to provide traveler information in the following ways:

• Variable message sign (VMS): Variable message signs are electronic signs that can

display changing messages. Permanent Variable Message Signs (VMS) may be

utilized at the discretion of Region 1 Traffic Management and Operations Center


May 4, 2018


Page | 14

(TMOC) to notify motorists about incidents in the project area so that they can choose

to detour to an alternate route if needed.

• Portable changeable message signs (PCMS): PCMS is a portable electronic sign

that can display changeable messages. They are useful when informing drivers of

upcoming construction periods and warning drivers of construction activities as

needed.

• Ground mounted signs: Typically installed at the endpoints of work zones informing

motorists of road construction and the possibility of delay. Ground mounted signage

will be needed to alert motorists of the availability of Highway Advisory Radio

information if/when provided.

• 511 (Highway Advisory Telephone): Inclusion of this project on ODOT’s statewide

511 highway advisory telephone system will help provide travelers with up-to-date

information about construction activities and potential delays.

• TripCheck (ODOT’s ITS Website): Including this project on ODOT’s ITS website

(www.tripcheck.com) will help to inform users of construction activities. TripCheck

allows motorists to retrieve real time information and weather conditions via the

Internet. In addition to the Internet, motorists may also call 511 to receive this same

information. ODOT also shares this information with WAZE so users of the popular

application receive notifications when approaching construction zones.

Construction Strategies

Useful construction strategies as they pertain to this project are described below.

• Planned lane closures: Temporary lane closures, when required, will be limited to the

off-peak periods.

• Project phasing: Maintaining the existing travel lane configurations in each direction

during construction will create less delay for motorists. Phasing construction activities

to minimize the number of lane closures will minimize impacts to traffic. Although

phasing requires a longer construction period, its reduced impacts to traffic should be

beneficial.

• Truck Traffic/Permit Restrictions: No width or height restrictions have been identified

at any of the project locations.

• Coordination with adjacent construction: The coordination of this project with other

projects in the area, as discussed in Section 4, will help to avoid unnecessarily

compounding traveler delay.

• Full-time traffic control supervisor (TCS): Having a full-time TCS on-site allows one

person to be dedicated to traffic control and not be distracted by other construction

activities. Benefits include the ability to make quick decisions and to implement

contingency plans as needed.

Alternate Route Strategies

Alternative routes for motorists should be identified whenever a full roadway closure is

anticipated during construction for more than 20-minutes. Based on the current staging strategy,

alternative routes (detours) should not be required.

Proposed construction Staging

Multiple staging options were explored for the proposed vehicle and pedestrian facility

improvements. The options considered included staged construction, temporary traffic

diversions and a full closure of roadway. The options considered have been included in ODOT’s

Decision Tree Matrix (Form #734-5042) to document the staging options and the reasoning

behind the decision for their use on the project. The Decision Tree Matrix has been included in

Appendix A.

The following outlines the preferred construction staging option for all project locations. Staging

has been developed to accommodate heavy vehicles at both locations. Complete plans for the

construction has been included in Appendix B.

OR8 (Baseline Street) at OR219(S 1st Avenue)

Concept

Allow reconstruction of the traffic signal system, illumination system and ADA pedestrian ramps

at up to one corner at time. Construction will be coordinated with the OR8 (Oak Street)/OR219

(S 1st Avenue) intersection construction. Up to two corners, one at each intersection on the

same side of OR 219, can simultaneously be under construction at any given time. Single lane

closures along OR8 and OR219 will be required to facilitate construction activities.

A six-stage construction strategy has been developed to facilitate both pedestrian and vehicular

traffic at the intersection. The southwest corner of the intersection will be reconstructed one half

at a time. This will allow the second half to remain open to pedestrian traffic and minimizes

disruptions to one direction of vehicular traffic at a time.

Construction for the northwest and southeast corners of the intersection will be completed using

pedestrian detours at adjacent intersections. Considerations for this type of temporary traffic

control includes:

• Northwest Corner: Shrubbery that prohibits temporary easement behind construction

zone and a single ramp design

• Southeast Corner: Existing business sign and extensive landscaping.

Since there is only a single ramp proposed on the northeast corner, it will also be constructed

under a single stage by providing a temporary alternative pedestrian accessible route behind

the existing curb ramp and by installing a temporary crosswalk along OR8 (Baseline St.).

This strategy allows for three legs of the intersection to remain open at all times. Lane closures

will follow ODOT’s TM800 Series Standard Drawings. The Temporary Pedestrian Accessible

Route Plans showing the staging is included in Appendix B.


May 4, 2018


Page | 16

Temporary 20-minute full closures are anticipated for removal of the existing mast arm

associated with the traffic signal system.

Vehicle Detour

No vehicular detours are anticipated at this intersection.

Pedestrians Accommodations

Temporary accessible routes will be provided for pedestrian traffic at two of the four corners. At

these corners, temporary construction easements can be obtained to route pedestrian traffic

around the work zones, outside of the vehicular travel lanes.

On the northwest and southeast corner, due to site constraints a pedestrian detour route per

ODOT Standard Drawing TM844 will be implemented at adjacent intersections. Alternative

pedestrian routing can be provided by closing travel lanes on OR8 and OR219 to provide a

temporary accessible route within the vehicular travel lanes.

On the northeast corner, along with a temporary easement for routing pedestrians around the

work zone, the crosswalk on the east leg of the intersection will temporarily be relocated to the

east since OR8 (Baseline Street) is one-way westbound. This will keep the route open at all

times during reconstruction of the northeast corner.

Figure 3: Construction Staging at OR8(Baseline Street) / OR219 (S 1st Avenue)


May 4, 2018


Page | 17

Bicycle Accommodations

There are no dedicated bike facilities that exist along OR8 (Baseline Street) or OR219. Bikes

will be required to share the vehicle lanes as they do under permanent conditions.

OR8 (Oak Street) at OR219 (S 1st Avenue)

Concept

Allow reconstruction of the traffic signal system, illumination system and ADA pedestrian ramps

at up to one corner at time and reconfigure the lane geometry of the north leg. Construction will

be coordinated with the OR8 (Baseline Street)/OR219 (S 1st Avenue) intersection construction.

Up to two corners, one at each intersection on the same side of OR219, can simultaneously be

under construction at any given time. Single lane closures along OR8 and OR219 will be

required to facilitate construction activities.

An eight-stage construction strategy has been developed to facilitate both pedestrian and

vehicular traffic at the intersection. Each corner will be reconstructed one half at a time. This

will allow the second half to remain open to pedestrian traffic and minimizes disruptions to one

direction of vehicular traffic at a time.

The exception to the half corner reconstruction staging, is the northwest corner of the

intersection. Due to restrictions from shrubbery and a private sign, this corner will be

constructed half at a time to limit impacts to traffic, but will require pedestrian detours setup at

adjacent intersections.

The strategy allows for three legs of the intersection to remain open at all times. Lane closures

will follow ODOT’s TM800 Series Standard Drawings. The Temporary Pedestrian Accessible

Route Plans showing the staging is included in Appendix B.

Temporary 20-minute full closures are anticipated for removal of the existing mast arm

associated with the traffic signal system.

No vehicular detours are anticipated for construction at this intersection.


Temporary accessible routes will be provided for pedestrian traffic at three of the four corners

where the half corner staging is implemented. At these corners, temporary construction

easements will be obtained to route pedestrian traffic around the work zones, outside of the

vehicular travel lanes. On the northwest corner, due to site constraints a pedestrian detour

route per ODOT Standard Drawing TM844 will be implemented. Alternative pedestrian routing

can be provided by closing travel lanes on OR8 and OR219 to provide a temporary accessible

route within the vehicular travel lanes.


There are no dedicated bike facilities that exist along OR8 (Oak Street) or OR219. Bikes will be

required to share the vehicle lanes as they do under permanent conditions.

Figure 4: Construction Staging at OR8(Oak Street) / OR219 (S 1st Avenue)

OR8: SE 44th Avenue to SE 45th Avenue Pedestrian Crossing

Concept

Construction will be conducted under four stages. Single lane closures will be required to

facilitate construction. A full 20-minute closure is anticipated for removal of the existing

overhead flashers, signs and span wire.

• Stage 1: To allow for construction of the pedestrian ramp, rectangular rapid flashing

beacon system and improvements to the existing bus stop area on the southside of OR

8, the existing bus stop will be temporarily moved to the west under the first stage of

construction. A shoulder and/or single lane closure is anticipated.

• Stage 2: Under stage 2, the bus stop on the southside of OR8 will be moved back to its

existing location. Buses and pedestrians will use the new ADA ramp constructed under

Stage 1. A shoulder and/or single lane closure is anticipated.


May 4, 2018


Page | 19

• Stage 3: Under Stage 3, improvements along the northside of the roadway will

constructed. Pedestrians will be routed along the existing sidewalk and pedestrian ramp.

Construction activities are planned to occur behind the sidewalk. A shoulder and/or

single lane closure is anticipated.

• Stage 4: Under Stage 4, improvements within the median will be constructed. This is

anticipated to consist of tactile warning surface replacement. Pedestrians will be routed

around the active surface replacement. A single lane closure is anticipated for one

direction of travel depending on the side of the median being worked on.

Vehicle Detour

No vehicular detours are anticipated at either intersection.


• Stage 1: Relocation of the bus stop will allow pedestrians to be routed from the west

along the shoulder to the existing crossing location to cross OR8.

• Stage 2: Pedestrians will be routed along the existing sidewalk and ADA ramp and

escorted past the work zone during construction hours. Construction activities are

planned to occur behind the sidewalk except for tactile warning surface replacement

and illumination pole footing installation.

• Stage 3: This is anticipated to consist of tactile warning surface replacement.

Pedestrians will be routed around the active surface replacement.


• Stage 1: Eastbound bikes will be routed along the existing bike lane. Bike lane will be

used as a shared facility with pedestrians during this stage of construction.

• Stage 2: Westbound bikes will be using the existing permanent bike facility.

• Stage 3: Bikes will utilize existing permanent bike lanes in both the eastbound and

westbound directions.
