The Project 

The goal of the SR432/ California Way Intersection project is to improve traffic and freight flow for all movements through the intersection and reduce travel time. 

The SR432/ SR411 on-ramp and off-ramp Interchange improvements were completed in 2021. 

The SR432/ California Way Intersection project scope includes a geometric realignment of SR432 from the railroad crossing to California Way Intersection and provides for: 

  • Widening of the travel lanes to 14 feet
  • Widening of the west leg at SR432 / California Way intersection to provide more separation between the westbound movement and eastbound left-turn lane
  • Added westbound through lane at SR432 / E. Industrial Way to provide additional queueing capacity for the westbound through lane at SR432/ California Way Intersection 
  • Replacement of the existing traffic signal and illumination system 
  • Improved signal timing and phasing of the intersections 
  • Pavement overlay and striping 


Project Funding


The project is funded through the 2019/2020 National Highway Freight Program Federal Funding as part of the two-phase improvements of the SR432 Corridor at two locations SR432/ SR411 on-ramp and off-ramp Interchange and SR432/ California Way intersection. The City received $5.3M in funding for these improvements.
