Weekend drivers are urged to stay clear of the Little River Turnpike and the Capital Beltway near Annandale this weekend.

Starting at 11 p.m. Friday, the westbound exit ramp of Little River Turnpike (Route 236) onto the Interstate 495 Beltway will be closed as workers add a new water line as part of the project to build High Occupancy Toll lanes on the Beltway. The roadway is slated to reopen by 5 a.m. Monday.
