Background
Early Public Perception Freeway is working OK—why do we need
to rebuild? No public will to endure major construction No public desire to fund major project “We will take care of it when it gets bad”
![Page 8: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/8.jpg)
BackgroundBy 1994, public begins to believe freeway needs to be rebuilt Congestion and travel times increasing Major deterioration visible
1995, UDOT created a team to lead the Project and move it to completion Project Director Financial Manager Structures Design MOT/Operations Staff Support
![Page 9: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/9.jpg)
Background
FEIS process Formal public meetings Open houses Community Councils Citizens groups NEPA process
Over 130 separate meetings

Conclusion of Research (1995)
Conclusion of Research (1995)
The public would prefer
a greater level of impact
in exchange for a
shorter construction duration
![Page 11: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/11.jpg)
Research
“Get in,
Get it Done,
And Get out!!”

Background
Original concept was traditional construction Design-Bid-Build
8-10 year duration
Investigated different and innovative design and construction strategies Design/Build was chosen in January ‘96 Construct project in 4 ½ years

Maintenance of TrafficMaintenance of Traffic
Large impact to traffic patterns
We need to take a different approach to managing traffic during construction

Process
Involvement process began early Met with mayors, city engineers, and public
works directors of affected jurisdictions 6 Cities, 1 County on corridor 8 Cities, 1 County off corridor
Received endorsement for D/B concept Presented preferred alternative and
potential construction schedule
![Page 20: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/20.jpg)
Parallel Streets
Reviewed routes along the corridor Identified capacity constraints, community issues,
and possible alternate routes
Identified 21 potential projects to make improvementsUsed a macroscopic model to evaluate potential improvements9 projects recommended for construction, with a value of $50 Million
![Page 21: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/21.jpg)
Parallel Street Projects
2 projects were ‘on the shelf’ Had completed EIS’s Widened a parallel route from 2 to 6 lanes
Remainder were ‘spot improvements’ Removed choke points Removed medians and added lanes Enhanced intersection capacity
![Page 22: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/22.jpg)
Parallel Street Projects
All projects were to be ‘fast track’ advertised by early 1996, with required completion prior to major construction beginning in summer 1997
UDOT Region assisted both with design and project oversight
![Page 23: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/23.jpg)

Emergency Responders
Created command structure, and created cross jurisdictional responses Best able to respond
Utah Highway Patrol was lead law enforcement agency
Alleviated fears of increased response time

Transportation Demand Management
Transportation Demand Management
A variety of methods for reducing transportation demand on the street system. Coordination with existing Utah Transit Authority
programs: Employee-sponsored bus passes (deep discount
program) Rideshare (carpooling) - computerized rider matching

Results
This indicated traffic was not entering local neighborhoods, as originally feared by residents
Parallel street projects provided route continuity and capacity
Public education informed motorists which routes were available
![Page 51: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/51.jpg)
Summary
The decision to fast track the project was driven by the public, not the Department
The public was a partner in the development of the MOT specification, through many outreach meetings and focus groups
![Page 52: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/52.jpg)
Summary
Local governments were a partner in the process, including the determination of early action item improvements to surface streets
Emergency responders were partners in the determination of restrictions on adjacent movements, and were involved intimately throughout the Project
![Page 53: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/53.jpg)
Summary
Other transportation industry stakeholders were partners, including the trucking industry, the recreation industry, bus transit, light rail, and the cab/private hire industry
The business community were partners in changing work and delivery schedules
![Page 54: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/54.jpg)
Summary
The media was a partner in providing up to date and accurate information to the public Traffic reporters were ‘in the loop’ on what
was going to happen
The approval rating of UDOT was higher than it had ever been Seen as responsive to the public needs
![Page 55: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/55.jpg)
Summary
Communication is the key If you aren’t sick of communicating, you
are not communicating enough
Work with all stakeholders, find common ground, and keep all commitmentsBe proactive when possibleBe reactive when necessary
![Page 56: Mitigating Traffic Impacts on Utah’s I-15](https://reader035.fdocuments.us/reader035/viewer/2022062720/5681355f550346895d9cc630/html5/thumbnails/56.jpg)
Summary
Maintain flexibility
Allow innovation
Think “outside the box”
Project mitigation begins long before the first barrel hits the pavement
