Inner Sunset Streetscape Improvement Project

Saturday, April 13: To accommodate the final phase of the Inner Sunset Streetscape Improvement Project, Muni will run bus shuttles for the N Judah Line between Ocean Beach and Carl and Cole streets starting Saturday, April 13 and will continue for approximately two weeks. Bus substitution is required in order to complete paving work on Irving Street between Arguello Boulevard and 9th Avenue.

Regular N Judah rail service will operate between 4th and King streets and Carl Street and Hillway Avenue. Carl Street and Hillway Avenue will be the last stop served by N Judah rail service. For stops west of Carl Street and Hillway Avenue, customers must transfer at Carl and Cole streets to continue their trip. Carl and Cole will be the last accessible rail stop.

Bus service will begin at 4:30 a.m., Saturday, April 13 and will continue during regular service hours until construction is completed. Bus shuttles will follow the regular N Judah line except for short segments along Frederick Street and Lincoln Way.

Customers traveling downtown are encouraged to allow extra travel time for their trips or consider taking alternate Muni routes, such as NX Judah Express, 6 Haight/Parnassus, 7 Haight/Noriega and 7X Noriega Express. Customers in the Inner Sunset area can also take the 43 Masonic or 44 O’Shaughnessy line to Forest Hill Station and transfer to Muni Metro lines for downtown travel. The L Taraval service is also available to connect downtown and the Sunset District.

Due to the ongoing need for additional bus operators during this time, Muni riders may experience additional gaps and crowding on the Chestnut, Geary and Mission corridors. The E Embarcadero and 83X Mid-Market Express lines will also be suspended until construction is completed. Alternate service will be provided by the F Market & Wharves and the N Judah trains:

• Along The Embarcadero, north of Market Street, use the F Market & Wharves historic streetcar.
• Along King Street and The Embarcadero, south of Market Street, use the N Judah train.
• Transfer between the N and F trains at Embarcadero Station and the Ferry Building.
