San Francisco is preparing for increased traffic due to construction on the Robert C. Levy Tunnel, also known as the Broadway Tunnel. The tunnel is located near several neighborhoods, including Russian Hill and Chinatown.

The construction project is expected to last 14 months, with partial closures starting on Monday. The tunnel has two bores, and one will be closed at a time, with the open bore carrying two-way traffic. Further details about the construction and traffic plans are available from San Francisco Public Works, who is overseeing the project.
