Dwight Way/California Street Intersection Project  




Project Purpose:

To increase safety at the Dwight Way/California Street intersection, particularly for pedestrians and bicyclists.  There has been a history of collisions and near-collisions at this intersection.

Project Status:

  • City Work:  The City has completed  Phase 1, which includes pedestrian improvements. A notice of construction (link here) was issued to residents within one block of the Dwight Way/California Street intersection prior to that date.  The below graphic provides a general overview of Phase 1 work.




  • EBMUD Work:  Immediately after the completion of Phase 1, East Bay Municipal Utility District (EBMUD) will replace a water line under the Dwight Way/California Street intersection.  The water line is located primarily under the westbound lane of Dwight Way and may affect westbound through traffic during EBMUD’s working hours (Monday-Friday, 8 a.m. – 5 p.m.), resulting in temporary detour(s).  Pedestrian and bicycle access across Dwight Way will be maintained during construction, and at least one marked crosswalk across Dwight Way will remain open at all times.

EBMUD mailed a notification to nearby residents of this work.  A link to view the postcard is here.  EBMUD will coordinate specifically with residents affected by temporary interruption of water service and/or driveway access restrictions.  For questions, contact EBMUD at 510-287-7208 or


  • City Work: An upcoming Phase 2 will involve construction of a temporary median refuge island on Dwight Way and evaluation of traffic data to determine if additional traffic controls are warranted and implementation of any such traffic controls, as described in the Project Update, Selected Alternative, and Questions & Responses document referenced below.
  • City Work: Phase 3 work is dependent on the results of the traffic evaluation in Phase 2.  At this time, Phase 3 is envisioned to construct a more permanent median refuge island, repave the intersection roadway, apply a pavement coating on a portion of California Street north of the intersection, and install new pavement markings.  The schedule for Phase 3 is dependent upon the completion date of the Phase 2 traffic evaluation.
