After announcing a series of changes to 14th Street NW in Columbia Heights in February, the District Department of Transportation will kick off construction on a new set of bus lanes along the bustling corridor this week.

The bus lanes will stretch along 14th Street between Euclid and Newton streets NW, with construction starting on or around June 11, DDOT says in a release. The construction is expected to take between 60 and 90 days, and DDOT says it will study the impact of the overall project on traffic over the next year.

In a statement Wednesday, Jeff Marootian, the agency’s director, said the bus lanes and other associated transportation changes would be “essential” for area residents. City officials anticipate that the bus lanes will improve service on the D.C. Circulator’s Woodley Park–Adams Morgan route as well as Metrobus lines 52, 54, and 59.

The lanes will be designated by red curb lanes and flex posts. Cyclists will be allowed to use them, too.

The project will consolidate bus stops to minimize travel times, placing stops every other block instead of every block. DDOT says 74 parking spots will be eliminated to make room for the new dedicated bus lanes. The agency didn’t immediately respond to a request for comment about how the prospective traffic changes would be enforced.

“This project also includes a protected bike lane and new pick-up/drop-off zone on 14th Street NW between Irving Street NW and Park Road NW; and a new northbound left turn lane at Newton Street NW, which will help alleviate traffic congestion,” DDOT says in its release.

The part of 14th Street leading north into Columbia Heights is among the busiest in the city. In 2017, roughly 3,500 pedestrians and 1,500 vehicles passed through the intersection of 14th and Irving streets NW during the usual afternoon rush hour, according to city data. The stretch has also been the site of numerous car crashes, with many nearby intersections considered some of the most dangerous in D.C.
