W&OD Trail Detours In Arlington Begin Tomorrow For Construction Of New Trail Bridge Over Route 29
Custis Trail detour near Bon Air Park begins in May for I-66 Eastbound Widening Project

FAIRFAX, Va. – Detours begin Friday, April 19, 2019, on the Washington & Old Dominion (W&OD) Trail for construction of a new trail bridge over Route 29 (Lee Highway) near the Arlington-Falls Church line. Additionally, the Custis Trail will be detoured beginning in May where it passes under I-66 near Bon Air Park in Arlington due to I-66 Eastbound Widening construction above the trail. Both detours are expected to last until fall 2020.

Details include:

Washington & Old Dominion Trail Bridge Detour at Lee Highway in Arlington (April 19, 2019, to Fall 2020)

On April 19, 2019, 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.

  • 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.

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.

Custis Trail I-66 Underpass Detour Near Bon Air Park (May 6, 2019 to Fall 2020)

On May 6, 2019, weather permitting, the Custis Trail will close where it passes under I-66 near Bon Air Park in Arlington. 

  • 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.

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. 

W&OD Trail Bridge construction and I-66 Eastbound Widening are components of the Transform 66 Inside the Beltway Eastbound Widening Project. The I-66 Eastbound Widening Project will add a travel lane along four miles of eastbound I-66 and install approximately 12,000 linear feet of new and replacement noise barriers. The project also includes constructing a new direct access ramp from eastbound I-66 to the West Falls Church Metro Station at the Route 7 interchange. Learn more about the project at inside.transform66.org.


The additional eastbound lane is scheduled to open to traffic in fall 2020, and the overall project is expected to be complete in fall 2021.
