Fairfax County officials gathered yesterday (Thursday) to celebrate the groundbreaking of a new bicycle and pedestrian bridge for the Washington & Old Dominion Trail over Wiehle Avenue in Reston.
The $6.7 million project replaces an at-grade crossing and widens Wiehle Avenue from Sunset Hills to the Reston Fire Station and Pupatella Pizza entrances, according to the county. It will also accommodate future 5-foot-wide bicycle lanes.
The project, which is managed by Allan Myers VA, will wrap up by late spring to early summer of 2024, according to the county.
It’s intended to improve transportation safety in the area by eliminating conflicts between vehicles and trail users and minimizing rear-end crashes.
Since June 2018, 11 crashes at or near the existing crossing were reported, according to state data.

“The W&OD Trail is a heavily traveled regional pedestrian and bicycle trail in Northern Virginia. We estimate the number of daily trail users at the W&OD trail crossing at Wiehle Avenue is as high as 3000,” the county said.
The project was funded by federal and state grants.
As construction continues, the asphalt trail will remain open except from 9 p.m. to 5 a.m.
A 6-foot-tall safety fence will be installed on the asphalt trail to separate the trail from the construction area. Meanwhile, the gravel trail will be closed on the west side from 11480 Sunset Hills Road to the east from Michael Faraday Court.
