Two left lanes of Interstate 395 between the Turkeycock high occupancy vehicle (HOV) entrance and Edsall Road will be closed on Wednesday through Aug. 25.
The Virginia Department of Transportation (VDOT) will lose the lanes to work on barrier placement as part of the 95 Express Lanes project.
Only one right lane will be open. The lanes will be closed from 10:30 p.m. to 5 a.m. on Wednesday and Thursday and 11 p.m. to 9 a.m. on Friday and Saturday.
Motorists are advised to expect delays. The HOV lanes will also be closed in the evening during work hours.
