Broadway Tunnel Closure & Upgrades | San Francisco News

San Francisco’s iconic Broadway Tunnel is shutting down for a major seismic upgrade and renovation starting August 15th, with a full weekend closure from Saturday morning to Monday morning. The $76 million Chinatown Public Health Center project, built directly atop the tunnel, requires critical structural work. After the initial shutdown, partial closures will last 14 months, with one tunnel bore closed at a time for seven months each—keeping one lane open in each direction. Expect delays, especially during rush hour, with detours via Union and Pacific Streets. The upgrade includes LED lighting and walkway improvements to make the historic 1952 tunnel safer and more user-friendly. This coincides with other Chinatown construction, so check the Public Works site for updates. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
