Multi-Asset Rehabilitation & Roadside Safety Project

Multi-Asset Rehabilitation & Roadside Safety Project Map

Caltrans has begun a multi-asset rehabilitation project along U.S. 101 that stretches from the northern border of San Mateo County in South San Francisco to the southern border in East Palo Alto. The $177M project includes:

  • paving
  • guardrail improvements
  • transportation management system enhancements
  • drainage upgrades
  • Americans with Disabilities Act-compliant curb ramps

The project will bring operational improvements and promote economic vitality in the region. The project is funded by the State’s Highway Operation and Protection Plan (SHOPP), a “fix-it-first” program that funds California highway repair and preservation.
