Project Description

The Metropolitan Transportation Commission (MTC) is undertaking the West Grand Avenue Bus/HOV Lane Project in the City of Oakland to provide operational improvements and increase person throughput on the San Francisco-Oakland Bay Bridge (SFOBB).

Construction for Phase 1 was completed in January 2019, which converted the existing right shoulder along the on-ramp to the SFOBB to a Bus/HOV lane.

Phase 2 is expected to open mid-2021 and will provide additional access and operational improvements for carpools and buses by converting the existing westbound right shoulder on West Grand Ave between the I-580 eastbound on-ramp and the intersection of West Grand Ave with Frontage Road. In addition, a multi-use path for bicyclists and pedestrians will be constructed on eastbound West Grand Ave between Maritime Street and Mandela Parkway.

Presentation Notes

  • Phase 1 project opened January 2019 added 1300’ of bus/HOV-only lane 
    • Travel time savings of up to 20 minutes for buses
    • But still excessive queueing leading up to the bus lane, especially around Maritime Street
    • Crashes on the bridge can increase bus travel time up to a half hour to travel only a half mile—Usually only 1 minute in non-peak traffic
  • Phase 2 project proposes the following:
    • Bus/HOV lane westbound by converting existing shoulder from Frontage Road to Maritime Street
    • Multi-use 2-way path on south side of West Grand between Mandela and Maritime by extending existing sidewalk. It would be 8’ wide with a 2’ barrier.
    • Construction expected in 2nd half of 2021.


  • Path will open up access to a lot more people in West Oakland.
  • Protected intersection proposed at Mandela/West Grand—design still in the works. May use existing median along Mandela to help bike riders make turns on and off the cycletrack. The next draft should be available within a few weeks.
  • How will pedestrians access the path?
    • Overpass touches down at West Grand/Campbell. Pedestrians can access it from there or to the east.
  • Is the path off the side of the existing overpass or part of the existing structure?
    • Path will be on-street, by widening the existing sidewalk.
  • The long term West Oakland Link project proposes to build a separated bike/walk overpass at this location, so this project is a short term interim upgrade.
  • The project is a part of the Bay Bridge Forward initiative to improve transit time and access for multiple modes.
  • Project will be going to city council in coordination with West Grand paving & road diet project, which will add buffered bike lanes from Mandela to Market Street.
  • MTC is working with Caltrans and Oakland city council to get design approval.
