San Francisco Public Works began a 14-month partial closure of the Broadway Tunnel on Monday as part of the Chinatown Public Health Center renovation project.
One lane will remain open in each direction through the tunnel, with motorists warned to expect delays during peak travel times. The work is scheduled to continue through October 2027.
The closure affects the Broadway Tunnel on Broadway between Larkin and Powell streets. Motorists are advised to plan their routes ahead.
The 1,616-foot tunnel, which opened in 1952, is officially named in honor of the late Robert C. Levy, a former San Francisco civil engineer and superintendent of building inspection.
