A stretch of K Street in Northwest Washington is about to get a makeover that could impact traffic until at least the summer of 2013.

Construction on K Street between 3rd and 7th streets NW is going to begin later this month and will last about 15 months, according to the District Department of Transportation.

The project, aimed at upgrading K Street, will involve utility replacement work, streetlight and traffic signal upgrades and repairs and resurfacing for sidewalks, alley entrances and driveways.

The work will take place Monday through Friday between 7:30 a.m. and 4 p.m. (There could also be some weekend work.)

This will complicate traveling on K Street between Mount Vernon Square and I-395. At least one lane will be kept open in each direction on K Street and the roads that cross K Street within this stretch, officials said. Some traffic lanes will be periodically shifted due to the work zone, and there could also be some flagging operations outside of rush hour. Drivers are encouraged to avoid using K Street during this project.

Parking will be restricted on both sides of the street, while pedestrians and bicycle riders could encounter detours or closures on bike lanes and sidewalks.
