State transportation officials are negotiating with a consultant to complete a feasibility study about the future Town Center Parkway underpass.
The underpass, which is listed as a top priority in Reston’s transportation funding plan, would extend Town Center Parkway from Sunrise Valley Drive west of Edmund Haley Drive under the Dulles Toll Road to Sunset Hill Road.
The structure would also include bike and pedestrian facilities that link mixed-use areas north and south of the toll road.
So far, the project is expected to cost roughly $170 million.
Currently, the Virginia Department of Transportation is negotiating with a consultant to conduct a feasibility study.
Once completed, the underpass is expected to relieve congestion and give commuters a different option for heading north and south in the area beyond Fairfax County Parkway and Reston Parkway.
The project isn’t expected to be completed until 2032. Before then, county officials estimate environmental assessment, engineering and design will take four years, while construction, right-of-way, and land acquisition could take around five years.
