Project Description

The project is on State Route 4 in San Joaquin and Stanislaus Counties. The project limits run from the State Route 99/State Route 4 Interchange in San Joaquin County to about 1.6 miles west of the Stanislaus/Calaveras County line in Stanislaus County.

Project Benefits


The purpose of the project is to:

  • Repair the roadway pavement
  • Rehabilitate culverts
  • Comply with Americans with Disabilities Act requirements
  • Address nonstandard features within the project limits, such as bridge rails and signs.


The pavement along State Route 4 within the project limits has deteriorated and needs to be repaired. Also, Americans with Disabilities Act deficiencies along the route in Farmington need to be upgraded. Nonstandard features within the project limits, such as bridge rails and updated signs that no longer meet current Caltrans standards, need to be updated.


Funding Source

The project was programmed in the 2020 State Highway Operations and Protection Program (SHOPP) with funding from the Pavement Preservation Program.
