Extended Lane Closures on I-66 East in Arlington Tomorrow Midday Through Saturday Night for I-66 Eastbound Widening Project VDOPT

Extended lane closures will occur on I-66 East between the Dulles Connector Road and Sycamore Street from 10 a.m. tomorrow, Friday, April 10, through midnight, Saturday, April 11, for the I-66 Eastbound Widening Project. Single- and double-lane closures will be needed for bridge joint reconstruction work over Williamsburg Boulevard and Westmoreland Street. At least one travel lane along I-66 Eastbound will be maintained at all times during this work.

Details include:

  • From Friday, April 10, at 10 a.m. through Saturday, April 11, at midnight, one lane will be closed on I-66 East from the Dulles Connector Road to Sycamore Street.
  • On Friday, April 10, from 8 p.m. to 9 a.m., and Saturday, April 11, from 8 p.m. to midnight, an additional lane will be closed on I-66 East from the Dulles Connector Road to Exit 69, Washington Boulevard/Lee Highway (Route 29), with one lane remaining open.

These extended lane closure hours will allow work to progress and minimize the number of overnight closures required to complete bridge joint reconstruction. Work is weather dependent and will be rescheduled if inclement conditions occur.

Drivers are urged to use caution and expect possible delays. Real-time traffic conditions and information is available at or through the 511 Virginia mobile app.

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 building a new bridge over Lee Highway (Route 29) for the Washington & Old Dominion (W&OD) Trail, and constructing a new direct access ramp from eastbound I-66 to the West Falls Church Metro Station at the Route 7 Interchange.

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. Learn more about the I-66 Eastbound Widening Project and sign up for project updates and lane closure alerts at
