7:15 A.M. Update:

A lot of commuters heading out this morning are going to find a new setup on the 14th Street Bridge. Drivers heading north on the bridge will find half of the left center lane on the north end of the bridge blocked off due to construction. This will lead to extra congestion on the bridge as well as for northbound traffic on the G.W. Parkway in Virginia.

The Post’s Dr. Gridlock recommends drivers use the far left lane. If you approach from the left two lanes, you won’t need to change lanes to go to 14th Street. Traffic is splitting around a construction island, but the two left lanes continue accessing 14th Street. This being a new pattern, you can expect there to be some delays and hiccups as people adjust.

If you’re in the far left lane but want to head to the Southeast-Southwest Freeway, just move right as soon as you are safely able to do so. You’ll have less time to make that move, but you should still use caution. The right three lanes on the bridge can access that freeway.

This new phase, the sixth of eight construction phases, is scheduled to last six to eight weeks. All the reconstruction work on the bridge deck surface is scheduled to be done this fall.

The inner loop of the Beltway is slow at Gallows Road.
