Staging Areas Established for Twin Peaks Tunnel Construction in Fall

Thank you for your continued interest in the Twin Peaks Tunnel Track Replacement Project.

Our contractors, NTK Construction, are steadily gearing up for construction inside Twin Peaks Tunnel. Though construction is not scheduled to start until the fall, crews have established a staging area on the west (West Portal) side of the tunnel to store materials and equipment for quick access while they work. Another staging area on the east (Castro) side of the tunnel is expected to be established in August. The staging area on the west side of the tunnel is along Junipero Serra Boulevard between Ocean Avenue and Sloat Avenue. The staging area on the east side of the tunnel is along Market Street between Collingwood Street and Castro Street.

These areas are vital for storing construction materials and equipment needed to complete the track replacement and help avoid production delays. Through August, crews may begin prep work, such as welding or installing protective fencing, in these staging areas to prepare for the construction in the fall. 

If you have any questions about the staging areas or the project, please contact Public Information Officer Kelley McCoy (kelley.mccoy@sfmta.com or 415.701.5428).

In an effort to keep the Muni system in working and safety condition, the SFMTA will be replacing the light rail tracks and track infrastructure inside the Twin Peaks Tunnel, which runs between Castro and West Portal Muni Stations. This construction project is an important preventative maintenance measure to ensure that our Muni rail system remains in good working condition and avoids unplanned service disruptions. Along with the track replacement, other improvements and repairs will be completed, including repairs to the tunnel walls and drainage system, and seismic improvements to the original east tunnel portal area.

 

Thank you for your understanding as we keep San Francisco’s Muni system running!
