SDSU Tunnel & Station

SDSU Tunnel & Station includes transit tunnels, a 50,000-square-foot trolley station, and a 14-ton arched suspension bridge for pedestrians. The project consists of four main areas: a 900-foot west section; approximately 1,070 feet of sequentially mined and constructed tunnel; the central station; and the 1,000-foot east section. Constructed under and through the San Diego State University (SDSU) campus, the 4,000-foot tunnel and station connects to the Mission Valley East extension project.
