T.Y. Lin International (TYLI) was contracted by the San Diego Association of Governments (SANDAG) to complete the final design of Segment 2 of the South Bay Bus Rapid Transit (BRT) Project.
Designed to emulate rail service, the South Bay BRT is a 22-mile-long system that uses existing streets and highways as well as portions that comprise a dedicated BRT guideway within local streets. It stretches from the southern part of San Diego County, near the Otay Mesa crossing of the U.S.-Mexico border, to downtown San Diego.
Segment 2 consists of approximately 1.5 miles of dedicated guideway and crosses State Route 125 (SR 125), from the East Palomar Street/Olympic Parkway intersection to East Lake Parkway on the east side of SR 125. The segment includes the Santa Venetia and Otay Ranch Town Center BRT stations within the Otay Ranch community and a two-frame bridge through a greenbelt and over SR 125.
Other design elements included the in-road guideway, privacy walls, bus stops, modifications to existing traffic signals, new traffic signals, retaining walls, lighting, landscaping, irrigation, drainage and stormwater facilities, and more.
TYLI oversaw extensive community outreach and coordinated closely with the Metropolitan Transit System (MTS), City of Chula Vista, California Department of Transportation (Caltrans), SANDAG, private developers, and homeowner associations.
TYLI’s final design reflected community input on guideway and security lighting, bridge and retaining wall aesthetics, greenbelt landscaping, and privacy walls on the guideway.
- The project increases convenience and safety for BRT users while bringing aesthetic enhancements to local communities.
- TYLI utilized 3D modeling and context-sensitive methods to actualize the client and community vision for the Santa Venetia station, greenbelt guideway, and bridge over SR 125.
- Functionally, the Santa Venetia BRT station completes the intended community design by providing links to pedestrian walkways and bike paths that connect transit with nearby commercial and residential areas.
- For the greenbelt portion of the guideway, TYLI incorporated design details such as security cameras, structure finish, privacy wall, and lighting aesthetics to create a park-like recreational area for the community.
- A unique and complex bus detection and signaling system was developed and installed to prevent bus collisions along the single-lane, two-way bridge over SR 125.
