N Judah Sunset Tunnel Work Details

The Sunset Tunnel construction is scheduled to take place on 15 weekends between November 2014 and June 2015. So far we have worked on three weekends. The next tentative dates are the weekends of Jan. 23 and Jan. 30, 2015.


What to Expect during Weekend Construction:

  • Crews will work continuously from approximately 8 p.m. on Friday until 5 a.m. on Monday.
  • The majority of the work will take place inside the Sunset Tunnel and at the tunnel entrances.
  • Noise can be heard in the surrounding areas, especially when the trucks move the gravels in and out of the portal. We will balance this work between the east and west portals to make it less disruptive for one neighborhood.
  • Majority of gravel moving will take place from Friday night until Saturday afternoon at the west portal near Carl and Cole streets, and from late Saturday until Sunday afternoon at the east portal near Noe Street and Duboce Avenue.
  • We will do our best to keep the noise down, but 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 from Friday 12 a.m. to Monday 5 a.m. on both sides of Duboce Avenue from Steiner to Scott Street, and on both sides of Carl Street from Clayton to Cole Street.

Bus substitution service:

  • Bus shuttles will substitute for the N Judah rail service between Church & Duboce and Ocean Beach.
  • Bus substitution will start at about 7 p.m. on Friday and will operate during regular service hours until Monday morning.
  • The bus shuttles will follow the N Judah Line making regular stops except for the tunnel portion where buses will be operated on Haight Street.
  • Regular N rail service will continue to provide service between Caltrain Depot and Church & Duboce.
  • 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.


Other Ongoing N Judah System Improvement Projects: 
Maximizing construction opportunities, 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. Currently a crew is working on Irving between 3rd and 9th avenues. On the January 9 weekend, crews will be installing signal loops between the tracks at the intersections of Irving and 7th Avenue and Irving and 8th Avenue. The work will start at approximately 7 p.m. Friday and will continue until Saturday night. We will schedule the work to avoid late night noise. 

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 two new wheelchair accessible platforms on Judah and 28th Avenuehas been ongoing. Crews are working to reconstruct the inbound stop Monday through Friday. The stop is currently out of service. Muni customers can board N Judah rail car at the temporary stop at 27th Avenue. The work requires closure of traffic lanes.

The new platform will 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.

Thank you for your understanding and patience while we work to improve your Muni system.
