The San Francisco Municipal Transportation Agency will close the Twin Peaks Tunnel for one week to conduct necessary repairs to ensure safety and reliability of transit services.
During the closure, Muni bus shuttles will replace regular service at affected stations, and key routes like the J-Church and N-Judah will remain operational, ensuring minimal disruption.
A report from engineering firm HNTB emphasized the importance of these repairs, stating that while the tunnel is currently safe, proactive measures are essential to maintain safety long-term.
Factors such as the school calendar, contractor availability, and event schedules significantly influenced the timing of the Twin Peaks Tunnel closure to minimize impact on commuters.
