Metro is rolling out new bus service Monday on the busy 16th Street corridor in an effort to relieve crowding and cut down on long wait times.

Commuters along 16th Street Northwest, which connects midtown D.C. with popular neighborhoods including Columbia Heights and Mount Pleasant, have complained that they have had to wait in the cold as bus after bus, stuffed full with passengers, passed their stops. The problem gets worse on the southern end of the corridor, where S-line buses arrive already loaded with commuters from neighborhoods as far north as Silver Spring.
