Two-way traffic will run on the northbound side of Route 29 starting around 9 p.m. Friday evening, July 23, through Saturday evening, July 24. The traffic pattern will switch around 6 p.m. Saturday, with two-way traffic on the southbound side of Route 29 for the remainder of the weekend.

Message boards on I-66 and Route 29 are providing advance notice of lane closures and traffic stoppages. 

All work is weather dependent and will be rescheduled if inclement conditions occur.

The I-66 bridges over Route 29 are being reconstructed as part of the Transform 66 Outside the Beltway Project. The bridges are being lengthened, widened, and raised to accommodate the new Express Lanes and provide room for any future mass transit along I-66 and future widening of Route 29. This work is being done in phases in order to maintain traffic on I-66 throughout construction.
