PROJECT DESCRIPTION

The Chinatown station is one of four new stations on the $1.6 billion Central Subway project. The Central Subway is a 1.7-mile extension of the Third Street light rail line, known as the T-Third. The Central Subway project includes one surface station between Brannan and Bryant Streets and three underground stations. Two tunnels were constructed and competed in April 2015 using 20.6-foot diameter tunnel boring machines (TBMs). It is San Francisco’s first major subway since the Market Street subway and stations were completed in the 1970s. Chinatown Station (CTS): Located at the southwest corner of Stockton and Washington streets, the station headhouse will extend over 100 feet below ground. The platform and connection to the headhouse are constructed in soft- and mixed-ground using mined sequential excavation method.
