East Cypress Road Widening From Knightsen Avenue to Bethel Island Road

Phase 1 is Capital Improvement Project (CIP) 247, Phase 2 is CIP 310, and Phase 3 is CIP 302. The new roadway will be six lanes west of Jersey Island Road and four lanes east of Jersey Island Road. Project includes storm drain, water, sewer, median islands, landscaping, buffered bike lanes, sidewalks, streetlights, and 5 signalized intersections (4 new and 1 signal modification). Phase 2 of this project also includes a 10-foot diameter pipe Canal Undergrounding (Contra Costa Water District (CCWD) Segment 5A) at Jersey Island Road. Construction for Phase 1 began mid-July 2024 and is projected for completion in the winter of 2025. Access along East Cypress Road will be available at all times.
