Metrobus riders using four Northwest routes may see changes, as the Washington Metropolitan Area Transit Authority has proposed adjustments that augment, reduce or modify bus service there.

The biggest shuffle comes in the 14th Street NW corridor, with the proposed addition of a new limited-stop 59 bus between the Takoma and Federal Triangle Metro stations. Meanwhile, the existing 52, 53 and 54 routes would be revised with less frequent service and with new access to the Southwest waterfront, where considerable development is underway. These changes would go into effect in December.

Meanwhile, Metro is proposing additional service on the H1 line that runs from Catholic University to the National Mall through Columbia Heights, Dupont Circle and Foggy Bottom. The route currently only operates one-way during morning and afternoon rush hours, and the changes would add two-way service throughout the day starting in June.

Metro has also proposed changes to the 62 and 63 route, which heads south from the Takoma Metro station via Petworth. The proposal would increase service that would continue south to the Federal Triangle station rather than stopping at Georgia Avenue-Petworth. It also reroutes the 63 bus to exclusively follow 11th Street NW through Logan Circle rather than also using a stretch of 13th Street. The revisions would begin in June.

Lastly, on Wisconsin Avenue NW, the 96 bus — which reaches the Capitol Heights Metro station via Woodley Park, U Street, Union Station and RFK Memorial Stadium — would only go as far north as Newark Street rather than the Tenleytown Metro station. The proposed change, which Metro says would undo a temporary adjustment made during construction of Cathedral Commons, would take place in June.
