Detours are required 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 until November 2020 and will produce safer, more time-efficient trips for trail users when complete. Details include:

W&OD Trail Detour at Lee Highway

When: April 2019 through November 2020

Where: The W&OD Trail will shift to nearby, temporary routings on each side of Lee Highway (near mile marker 5.5).

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 November 2020.

Detours (Updated March 20, 2020):

• On the west side of Lee Highway, trail users will be shifted to a short stretch of new pavement running for about 200 feet adjacent to the W&OD Trail. This new route will connect with the signalized crosswalk at Lee Highway.
• 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 

When: September 2019 through November 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 November 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.
