About the Project

As a follow-up project to the recently completed 495 Express Lanes, this project will complete pedestrian and bicycle facility connections along Idylwood Road (Route 695) and Chain Bridge Road (Route 123), providing enhanced and safer pedestrian and bicycle access at I-495 in Fairfax County.

On Idylwood Road, a five-foot wide sidewalk will be constructed on the south side of the Idylwood Bridge across I-495, connecting with the sidewalk on the bridge. On Chain Bridge Road, a 10-foot-wide shared-use path will be constructed on the south side of I-495 between Tysons Boulevard and Old Meadow Road.
