After several years of planning and collaboration with South County communities, construction is underway on South Bay Rapid, a $128 million effort to provide travelers with a frequent and reliable transit choice. 

When completed, South Bay Rapid will include 12 stations along a 26-mile route from the Otay Mesa Port of Entry to Downtown San Diego via eastern Chula Vista, connecting to employment and activity centers in Downtown San Diego and South County.

At the heart of the project is the dedicated transit guideway – a nearly six-mile-long transit-only lane being constructed in the median of East Palomar Street and along Eastlake Parkway in Chula Vista. 

Construction is currently taking place in four areas within the cities of Chula Vista and San Diego:

  • East Palomar Street (Heritage Road to Olympic Parkway, Chula Vista) – this segment of the transit guideway is anticipated to be completed by fall 2017. Additional work will begin later along East Palomar between I-805 and Heritage Road.
  • Guideway Bridge/Eastlake Parkway (Magdalena Avenue to State Route 125, Town Center Drive to Birch Road, Chula Vista) – this segment includes the guideway bridge over SR 125 and the transit guideway adjacent to Otay Ranch Town Center. Work is expected to be completed in 2018.
  • Millenia Station (Millenia Project, Chula Vista) - construction began in September 2017 and is expected to be completed in 2018. Millenia Station will provide nearby residents with access to South Bay Rapid service, which is expected to begin in 2018.
  • Otay Mesa Transit Center (Nicola Tesla Court, San Diego) – construction began in June 2017 and is expected to be completed in early 2019. 

Rapid service in the South Bay is expected to begin in late 2018/early 2019 and will be operated by the San Diego Metropolitan Transit System.
