# SDSU Transit Center

SDSU Transit Center is a San Diego Trolley station on the Green Line and bus hub. It is located on the campus of San Diego State University (SDSU). The line connects the main campus with SDSU Mission Valley, a noncontiguous campus expansion which contains Snapdragon Stadium.
The entrances are between College Avenue and Campanile Drive. The station is underground (the only such station in the system), and has side platforms. The bus plaza opened in February 2005 while the trolley platforms opened on July 10, 2005, with the rest of the Green Line.

## History

In 1989, the San Diego Metropolitan Transit Development Board began developing plans for an additional trolley line connecting its Blue and Orange lines. The new line was initially expected to cost $506 million and cover 5.6 miles (9.0 km) of track. After initially looking at over ten different routes to connect the two lines, the board initially recommended connecting San Diego State University at the north end of its campus, near Interstate 8. However SDSU officials wanted the trolley station to go through the center of the campus, which would require tunneling underneath the campus. The board initially balked at this concept as it would increase construction costs by $40–50 million. Once the board learned that tunneling would be cheaper than purchasing adjacent land they agreed to alter the route. Final construction costs for the new trolley station were $103 million. Construction for the new trolley line first began in 1999.

### Construction

Several methods were used to excavate the tunnel that would contain the station and the tracks to be used for the trolleys to pass underneath the campus. 2,915 feet (888 m) (of the total 4,000 feet (1,219 m) of track) were excavated using the cut-and-cover method where a current road above the tunnel would have its pavement removed, the underlying ground entrenched, and the pavement for the road re-added. For the remaining 1,085 feet (331 m), the new Austrian tunneling method was used, which required the use of the geological stress of the surrounding rock mass to stabilize the tunnel.
Construction of the tunnel and station was designed (Began in September 1998) to minimally disrupt the campus and, as a result, it was halted during the opening weeks of each semester as well as finals. The station opened in September 2005 with sold out tickets purchased by students.

### Design

The trolley station was designed by the architect firm ZGF Architects. The station was initially designed to limit the noise of the passing trolleys, so as to not disturb classes on campus. In addition to blue cold cathode lighting, natural light enters the station from the street level above through 20 openings.

### Dedication

On June 29, 2011, the station was dedicated to Leon Williams, an SDSU alumnus and a former MTS board chair who was instrumental in bringing the light rail line to the heart of the SDSU campus.

### 2024 shooting

On 31 October 2024, a man was shot near the transit center, and was left with wounds not considered to be life-threatening. Two suspects were arrested in relation to the shooting.
