TOWN OF LEESBURG
TOWN COUNCIL WORK SESSION
Subject: East Market Street (Route 7) / Battlefield Parkway Interchange
Staff Contact: Tom Brandon, Capital Projects Manager, Public Works & Capital Projects
Calvin Grow, Transportation Engineer, Public Works & Capital Projects
Renée LaFollette, Director, Public Works & Capital Projects
Council Action Requested: Information only.
Staff Recommendation: Information only.
Commission Recommendation: Not applicable.
Fiscal Impact: A new grade-separated interchange between East Market Street and Battlefield Parkway
is estimated to cost $58 million. This order-of-magnitude estimate was prepared based on comparable
interchanges in the area. As part of the ongoing studies to select a preferred alternative for the
interchange, the estimated cost will be refined. However, based on work performed to date, the estimated
project cost appears to be in the right order of magnitude.
To date the Northern Virginia Transportation Authority (NVTA) has awarded a total of $33 million to
the project. This existing funding is sufficient for preparation or the required Interchange Justification
Report, preparation of an environmental document, design, right-of-way acquisition, relocation of
utilities, and a portion of the construction. The remainder of the funding has not been secured.
The Town will continue to apply for major project funding sources for full funding of the project,
including NVTA regional funding and Virginia Department of Transportation (VDOT) Smart Scale.
Other potential smaller funding programs from VDOT, NVTA and other sources will also be evaluated.
Work Plan Impact: None. This project is included in the Department of Public Works and Capital
Projects work plan. The studies, design and construction of the interchange are being administered by
the Virginia Department of Transportation, in cooperation with the Town of Leesburg and Loudoun
County.
Executive Summary: The initial stages are underway for the development of a grade-separated
interchange to replace the signalized East Market Street (Route 7) / Battlefield Parkway intersection.
The project will also include modification of the existing Cardinal Park Drive intersection with East
Market Street. As part of the preliminary design and the development of an Interchange Justification
Report, various alternative interchange configurations have been developed and are being evaluated.
This initial work on the project, including the preliminary design, traffic studies, Interchange
Justification Report, and environmental document is scheduled to be completed in spring 2018.
Scheduling of final design and construction of the interchange is dependent on future funding.

East Market Street (Route 7) / Battlefield Parkway Interchange
April 24, 2017
Page 2
Background: East Market Street (Route 7) is one of the most congested corridors in Leesburg. This
highway carries inter-state and intra-state traffic from the west and south to the employment corridors
and activity centers in the Dulles area and Washington, DC metropolitan region. Current weekday
traffic on East Market Street is estimated to be 85,000 vehicles per day and current traffic on
Battlefield Parkway is estimated to be 15,000 vehicles per day. During the afternoon peak hour,
approximately 8,000 vehicles pass through the Battlefield Parkway intersection resulting in routine
congestion. Also, the existing East Market Street signalized intersections with Battlefield Parkway
and Cardinal Park Drive have some of the highest accident rates in Loudoun County
In addition to motorized vehicle issues, East Market Street acts as a barrier separating residential areas
from retail and business areas.
Project Scope
In 2016, the Town entered into an agreement with the Northern Virginia Transportation Authority
(NVTA) for funding of preliminary studies and design for the interchange. The Town also executed
a separate agreement with the Virginia Department of Transportation (VDOT) in which they are
administering the work on the project. The purpose of the project is to:
Reduce recurring congestion at the Route 7 and Battlefield Parkway intersection
Improve safety
Improve accessibility for pedestrian and bicycle traffic crossing Route 7
One of the required steps to construct a new highway interchange is to develop an Interchange
Justification Report (IJR). The purpose of the IJR is to provide a reliable forecast of future traffic
conditions, develop and evaluate alternatives, and select an alternative that best meets the project
needs.
Alternatives
Four alternative interchange configurations for Battlefield Parkway, and four optional treatments of
the Cardinal Park Drive intersection have been developed for the project (drawings included in the
VDOT presentation attached):
The alternatives that have been developed for the Battlefield interchange are:
Alternate 1: Hybrid Diamond Interchange with a cloverleaf loop ramp in the northeast
quadrant – Variations of this type of interchange are found at several locations along Route 7
east of Leesburg.
Alternate 2: Compressed Urban Diamond – This type of interchange is at the intersection of
Route 7 and Fairfax County Parkway near Dranesville.
Alternate 3: Diverging Diamond Interchange – This type of interchange configuration was
recently constructed at the I-66 / Route 15 intersection in Haymarket.
Alternate 4: Single Point Urban Interchange- An example of this type of interchange
configuration is at the Route 7 / Loudoun County Parkway intersection in Ashburn.

Cardinal Park
Option A: Green T – This type of intersection allows the westbound through Route 7 traffic
to continue freeflow without a traffic signal. Westbound left turn to Cardinal Park Drive
would be controlled by a signal. This is similar to the intersection configuration on the Bypass
at Fort Evans Road. The left turning traffic from Cardinal Park Drive is separated from the
westbound Route 7 traffic by a barrier, and would not have direct access to the Bypass.
Option B: Right-In/Right-Out/Left-In – This type of intersection would not allow left turns
from Cardinal Park Drive to westbound Route 7. Traffic wishing to go westbound would use
Trailview Boulevard/Russell Branch Parkway and go through the new interchange. All other
movements at the intersection would be allowed and would be contolled by a signal, except
for Route 7 westbound through traffic, which would be free flowing.
Option C: Right-In/Right-Out – This type of intersection would allow traffic to leave the
Cardinal Park area and travel eastbound, but would not allow traffic to turn left and travel
westbound. Westbound Route 7 traffic would not have access into Cardinal Park.
Option D: Right-In Only – With this type of intersection, all traffic leaving Cardinal Park
would use Trailview Boulevard/Russell Branch Parkway to the new interchange at Battlefield
Parkway. Also, westbound Route 7 traffic would use the Battlefield Parkway interchange and
Russell Branch Parkway to access the Cardinal Park area.
Public Outreach
The development and approval of the IJR will include significant outreach to impacted stakeholders.
Information about the project is available on the Town’s website, and on a project web page
maintained by VDOT, which is located on their website at
http://www.virginiadot.org/projects/northernvirginia/rt_7_at_battlefield_pkwy.asp.
VDOT will begin meeting with individual business and property owners later this spring.
A formal Public Hearing will be held after completion of the draft IJR. This hearing is tentatively
scheduled for 1st Quarter of Calendar Year 2018.
Schedule
Below is the tentative schedule for approval of the IJR and the project design.
Spring 2017: Meetings with business owners, Public Information Meeting, and identification
of a preferred alternative.
Summer 2017: Complete preliminary design
Fall 2017: Conditional IJR approval
Early 2018: Public Hearing, additional briefings to Town Council and Board of Supervisors
Early 2018: Town and County endorsements
Spring 2018: Design approval
Final design, right-of-way acquisition, utility relocation and construction will be scheduled after full
project funding has been finalized.
