About the Project

This project will make interchange improvements at two locations—Fairfax County Parkway and Rolling Road, and Fairfax County Parkway and I-95—to help meet projected increases in future traffic demands.

Proposed improvement: Widen the one-lane loop ramp to two lanes from north and southbound Rolling Road to Fairfax County Parkway north.

Alternative E was selected, which will eliminate the existing free flow right exit onto the loop by bringing the northbound right-turn lanes to a signalized intersection. This would address a safety conflict between traffic entering the loop from the northbound direction and traffic entering the loop from the southbound direction.

Proposed improvement: Construct a flyover ramp from northbound I-95 to northbound Fairfax County Parkway.

To allow traffic to continue to access northbound Backlick Road and the future interchange at Boudinot Drive, the project will eliminate the existing loop ramp and build left-turn lanes at the end of the ramp at Fairfax County Parkway and Loisdale Road.


Traffic demand on these ramps is expected to increase over the next 20 years due to the extension of the Fairfax County Parkway, regional population and employment growth, and the Base Realignment and Closure (BRAC) efforts to the Fort Belvoir North Area, located west of I-95 and east of the Fairfax County Parkway.

Daily forecasted volume on the ramp from northbound I-95 to westbound Fairfax County Parkway as well as the ramp connecting northbound and southbound Rolling Road to westbound Fairfax County Parkway is expected to increase.

The existing ramps cannot adequately handle the forecasted volumes. The proposed project will address specific traffic deficiencies at the interchanges, namely the relatively low capacity of the one-lane loop ramps, to accommodate the increases.

Schedule and Cost

The total cost is currently estimated at $96.4 to $105.5 million, including $8.6 million for engineering, $24 million for right of way and utilities and $63.8 to $72.9 million for construction. A project construction schedule will be developed once funding has been identified.

The Rolling Road loop ramp (UPC: 100391, State Project # 0286-029-947) is currently under design build. Construction is scheduled to begin in late winter/early spring 2015 and be completed in spring 2016.

The I-95 flyover ramp (UPC: 93033, State Project # 0095-029-846) is currently under preliminary design up to the public hearing phase only.  It is not funded for right of way or construction.  The project advertisement date is to be determined based upon availability of funding.

Environmental Impacts

An environmental assessment was prepared and approved by the Federal Highway Administration for this project, and includes a full listing of considered impacts and additional findings from the environmental evaluation.
