After more than a decade of planning and community engagement, construction on the Central Avenue Safety Improvement Project will begin on Monday, January 27.

This project is designed to enhance safety for all users and reduce vehicle delays. The full length of the project spans 1.7 miles, but the biggest impact to the public will occur during the construction of three roundabouts, which will be completed in phases to minimize disruption.

Phased Construction Approach to Minimize Impact

  • Phase 1 (January-June 2025): Construction of roundabouts on Central and Third and Fourth Streets will involve the closure of one westbound lane between Fifth and Pacific.
  • Phase 2 (June 2025-January 2026): During this phase, construction continues on the roundabouts on Central and Third and Fourth Streets, with a single eastbound lane closure between Pacific and Fifth Street.
  • Phase 3 (April 2026): Construction of a roundabout at the intersection of Central/Pacific/Main will require the full closure of the intersection to through traffic. Detours will be established to direct traffic around the construction zone.

During Phases 1 and 2, full access will be maintained to Ballena Boulevard and Third Street south of Central Avenue. Pedestrian and bicycle access will be maintained throughout the project. For work outside the roundabout areas, at least one lane of travel will be open in both directions. Read more about the project at www.alamedaca.gov/central.
