Causeway Connection Bus Service Extended Through May 2025

UC Davis Affiliates Ride at No Charge!

Transportation Services and Sacramento Regional Transit (SacRT) signed a new memorandum of agreement (MOU) to extend the Causeway Connection service between Davis and Sacramento through May 3, 2025. 

Causeway Connection


The Causeway Connection (Route 138) is a zero-emission bus service free to all UC Davis Affiliates (students, faculty, academics, staff, retirees, and volunteers) managed by SacRT. The hourly service runs Monday through Friday and offers trips between the Silo Terminal at UC Davis and the UC Davis Medical Center in Sacramento. Barring significant traffic delays, a trip between the Davis Campus and UC Davis Health takes approximately 35 minutes. All trips serve the three Davis stops:

  • Mondavi Center
  • Genome Biological Science Facility
  • Silo Bus Terminal

By switching from natural gas to electric buses, the Causeway Connection helps to reduce regional emissions and congestion on the I-80 Causeway. We thank our riders for their continued support and feedback!
