Update at 10:00 a.m. — VDOT says the change has been postponed: “Please note this new pattern has been postponed until January due to additional signal work. A new date for the shift will be announced soon.”

A new traffic pattern will be in effect at the under-construction Columbia Pike and Washington Boulevard interchange starting Thursday.

VDOT says drivers heading eastbound on the Pike will now have a different way of getting to northbound I-395 (toward the District). Now, instead of bearing right after the light at S. Quinn Street, drivers will need to wait to turn left at the light, onto a new ramp to Washington Boulevard.

Those heading to southbound I-395 will still bear right onto the ramp after S. Quinn Street.

“Work to complete the switch will take place between 9 a.m. and 5 p.m. Thursday,” VDOT said in a press release. “Message signs will be in place to notify drivers of the new traffic pattern.”

“This new access is part of the $51.5 million project to replace the Washington Boulevard bridge over Columbia Pike,” the press release continued. “The project will be complete in summer 2015.”

As part of the project, the new bridge over Columbia Pike opened last month.
