As part of the Sunset Tunnel Trackway Improvement Project, the San Francisco Municipal Transportation Agency (SFMTA) will resume weekend construction on the Sunset Tunnel. The work will start at 8 p.m. Friday, Feb. 12 and continue until 3:30 a.m. on Monday, Feb. 15. During construction bus shuttle will replace the N Judah trains running between Ocean Beach and Church & Duboce.
The weekend work that has started previously on Saturday morning the past few months will begin on Friday night from now on. This way we can maximize the work window for the weekend.
After the weekend of Feb. 12, we will have performed 15 weekend shutdowns to complete over 80% of the work. There will be more weekend shutdowns scheduled for 2016. The tentative dates are Feb. 26-29 and Mar. 4-7. We are working diligently with the contractor to expedite the rest of the construction and will do the best we can to finish the work as quickly as possible.
Maximizing construction opportunities, the Transit Signal Priority (TSP) system upgrades will take place at the same time on Judah Street between 16th and 19th avenues, at the intersection of Irving Street and 4th Avenue and on Carl Street between Willard and Stanyan streets. During this work streets and intersections will remain open. The N Judah boarding platforms served by bus shuttles in the areas may be temporarily relocated.
What to Expect during Weekend Construction at Sunset Tunnel:
-
Crews will work continuously from about 8 p.m. Friday until 3:30 a.m. on Monday.
-
Noise control measures will be implemented; however the work will be audible throughout the weekend.
-
The streets near the tunnel entrances will remain open.
-
To accommodate the tunnel work, parking restrictions will become effective before the work starts on both sides of Duboce Avenue from Steiner to Scott Street, and on both sides of Carl Street from Clayton to Cole Street.
Weekend Bus Substitution Service:
-
While Sunset Tunnel is closed for construction, bus shuttles will substitute for the N Judah rail service between Ocean Beach and Church & Duboce during service hours from about 7 p.m. on Friday until end of service at 1 a.m. on Monday.
-
Regular N Judah trains will continue to provide service between Church & Duboce and 4th and King streets.
-
The N bus shuttles will follow the N Judah Line making regular stops except for the tunnel portion where buses will be routed to Haight Street.
-
The N Judah stops at Church & Duboce will provide a transfer point between bus shuttles and trains for Muni customers.
-
The weekend N Judah Owl bus service will not be affected.
-
Bus arrival predictions will be available on NextMuni for the N bus service.
Other Ongoing N Judah System Improvement Projects:
The SFMTA has integrated multiple construction components under the Sunset Tunnel project in order to minimize the inconveniences for both N Judah riders and the community around the construction area.
The Transit Signal Priority (TSP) system upgrades are taking place at nine intersections sequentially along the N Judah Line. This weekend crews will work at the three locations as mentioned above. Here is a note for the neighbors:
-
Work hours will be 8 to 10 p.m. Friday and 8 a.m. to 5 p.m. Saturday and Sunday.
-
During construction the streets will remain open; however there will be lane closures and traffic will be diverted.
-
The eastbound wheelchair accessible platform at 19th Avenue will temporarily move to the southwest corner of Judah Street and 20th Avenue.
-
The westbound accessible platform at 18th Avenue and the island stop at 16th Avenue will move to the curbside.
-
Bus shuttles will provide accessible service at the curb.
-
Street parking at construction site will be temporarily unavailable.
-
Driveway access will be maintained.
-
There will be noise during excavation of the sidewalk and roadway.
The TSP system will use technology to reduce dwell time at traffic signals for Muni light rail vehicles by holding green lights longer.
The construction of the wheelchair accessible platforms on Judah and 28th Avenue was successfully completed in late March 2015. The westbound and eastbound stops are now in service for the N Judah customers.
The new platforms include longer boarding islands and ADA (Americans with Disabilities Act) compliant curb ramps, making Muni Metro system safer and easier to use for all customers.
