The construction of the 14th Street Bridge is bringing a new traffic pattern for drivers starting on Monday.
Northbound traffic will be split around construction barriers, shifting three of the lanes to the left and one to the right, the District Department of Transportation said Wednesday.
Drivers also will face some lane closures overnight on the weekends. Traffic will share two lanes instead of four from 10 p.m. to 5 a.m. during those times.
The changes mean less reaction time for drivers to make their decisions, so road officials urge them to stay alert.
This phase of the project is expected to last up to five weeks. But it still has a ways to go: the scheduled completion is August 2011.
