Detours will begin in April on the Washington & Old Dominion Trail and the Custis Trail as part of a VDOT project in Arlington to improve multi-modal mobility in the I-66 Inside the Beltway corridor. Detours are expected to last into 2020 and will produce safer, more time-efficient trips for trail users when complete. Details include:

W&OD Trail Detour at Lee Highway (April 2019-Fall 2020)

When: April 2019 through fall 2020

Where: The W&OD Trail will close between Little Falls Street and Lee Highway (near mile marker 5.5) and for a short portion on the east side of Lee Highway.

What’s Being Done: A new bridge is being built for the W&OD Trail over Route 29. This bridge will provide trail users a safer crossing at this busy intersection. Upwards of 2,000 people use the trail in this area near mile marker 5.5 on peak days. The bridge is expected to open in fall 2020.

Detours:

• Pedestrians will be detoured to the north on Little Falls Street, then turn right on Fairfax Drive to reach the signalized crosswalk for Lee Highway. Sidewalk is available for this entire detour.
• Cyclists will be detoured to the south on Little Falls Street, turn left on West Jefferson Street to reach Lee Highway, then turn left on Lee Highway to the signalized crosswalk. Most of Jefferson Street does not have sidewalk.
• On the east side of Lee Highway, trail users will be shifted to nearby Fairfax Drive for about 200 feet. This portion of Fairfax Drive will be closed to vehicle traffic.

Custis Trail Detour Under I-66 (September 2019-Fall 2020)

When: September 2019 through fall 2020

Where: The Custis Trail will close where it passes under I-66 near Bon Air Park in Arlington.

What’s Being Done: An additional lane is being added to I-66 East between the Dulles Connector Road and Fairfax Drive / Glebe Road (Exit 71). Extensive work will occur on the bridge that runs above the trail, which requires the underpass to be closed for safety. As part of the construction, the Custis Trail alignment will be shifted slightly south, improving visibility and safety for trail users. Work is expected to be complete by fall 2020. 

Detour:

• Trail users will be detoured to cross over I-66 using an existing pedestrian bridge about 750 feet east of the underpass. The bridge can also be accessed from N. Fairfax Drive near Kensington Street.
• The detour will be marked and uses existing paved trails.
