District leaders on Monday introduced a new express bus service designed to reduce congestion along 14th Street and speed travel between the Takoma and Federal Triangle Metro stations.

D.C. Mayor Muriel Bowser made an inaugural ride on the MetroExtra 59 Express bus, which adds a new route along 14th street to supplement the existing 52 and 54 buses. The bus will operate during weekday peak hours in both directions, running every 15 minutes.

City officials said the new bus will address congestion along the 14th street corridor, which has seen a 20% increase in residential population over the last five years. The number of businesses has also doubled in the corridor during that time frame. According to Metro, about 15,000 riders travel along the corridor every day.

“The 14th Street corridor has seen substantial economic development and growth, making it one of the most heavily traveled corridors in the District,” Bowser said in a press release. “As the District continues to grow, we’re going to continue finding ways to make it easier for our residents to share in our prosperity.”

Bowser’s budget for fiscal year 2018 calls for $1.2 million to fund the MetroExtra59 bus.
