State Route 4 Delta Pavement Improvement Project
Project Description
This Capital Preventive Maintenance (CAPM) project on State Route (SR) 4 from Contra Costa County Line to 0.2 Mile East of South Whiskey Slough Road proposes to repair failed areas of pavement (dig outs) and then cold plane and overlay the existing pavement width from the eastbound edge of pavement (EP) to the west bound EP. Shoulder backing will be placed along the EPs in both directions. It also proposes to upgrade departure barriers, electrical elements of traffic management systems, lighting systems, and replace sign panels.
Project Benefits
Purpose
The purpose of this project is to preserve and extend the life of the existing pavement as well as improving the ride quality.
Need
The project is needed because the pavement within the project limits is exhibiting major distress and unacceptable ride quality, which if left uncorrected, would continue to deteriorate.
Funding Source
This project is programmed in the 2022 State Highway Operation and Protection Program (SHOPP) with funding from the 201.121 Capital Preventive Maintenance (CAPM) Program in the 2025/26 fiscal year.
