SR156 West Castroville Boulevard Interchange
Project Description
In Monterey County at Castroville Boulevard from Post Mile R1.4 to 1.6. Build a new interchange at Castroville Boulevard and Highway 156. The State Route 156 Castroville Interchange project is a safety, economic development, and congestion relief project in northern Monterey County, California, that will convert the existing at-grade signalized intersection at Castroville Boulevard into a new grade-separated interchange supported by roundabouts. The project will enhance safety for residents in the low-income rural community of Castroville, reduce traffic congestion for trucks traveling to and from the region’s largest agricultural distribution center, improve access for visitors to the world-famous Monterey Peninsula, and improve the quality of life for all communities along the corridor. Improvements also include approximately 1.3 miles of ADA compliant concrete multi-use path that will connect to the existing multi-use path that traverses over the railroad tracks from the community of Castroville, maintenance vehicle pullouts and a dedicated frontage road serving ingress and egress to the Monte de Lago housing development.

Project Benefits
Purpose and Need
The Castroville Boulevard intersection is the only at-grade signalized intersection along the 156 corridor that stretches from Castroville to the west and Prunedale to the east. This intersection has a much higher accident concentration than the statewide average for similar intersections. Construction of the interchange should reduce those accidents. Additionally, the signalized intersection reduces the operational efficiency of the whole corridor by causing queuing and congestion, thereby limiting the flow of goods and services. Construction of the interchange will increase efficiency along the entire corridor and reduce queuing and congestion by eliminating the signalized intersection.
