Media Tours Central Subway Tunnels
San Francisco Mayor Edwin M. Lee congratulates Central Subway Project Director John Funghi on completion of Tunnel Contract 1252. This contract consists of the 1.7 mile long twin tunnels connecting South of Market through Union Square and Chinatown. Also included in the contract (pictured here) is the tunnel portal located on 4th Street between Harrison and Bryant.
The twin tunnels are made up of precast concrete rings comprised of six segments, which are bolted together underground. Next steps for the Project include installation of track and systems to get revenue service ready by 2019.
Local and network media participated in a news conference earlier this week to see the completed tunnels firsthand.
