Overnight Paving Operation and Daytime Work Continues on State Route 183/Merritt Street in Castroville

MONTEREY COUNTY – Construction continues and is working towards completion on a major rehabilitation of State Route 183 (Merritt Street) in Castroville to enhance multimodal travel. This primary phase of work will result in nighttime resurfacing and paving of SR 183 beginning at the south end of Del Monte Avenue and working northward to State Route 1. After PG&E completed their work within the sidewalk areas, Granite then completed the sidewalk construction.

Reminder: Drivers must abide by speed limit laws everywhere.

At least one lane of traffic in each direction will remain open for travelers on SR 183 during night work closures. Paving on Merritt Street has been completed. Some paving on side streets where they connect with Merritt Street is still needing to be done. Contractors will work to place final and permanent striping configurations, install traffic signal control loops within the roadway, and work to raise ground utilities boxes to the new roadway grades. The landscape subcontractor will continue to install irrigation system and prepare the tree wells to start planting trees and other plants. The pedestrian railings will be installed in place once the fabrication is completed. Placement of concrete for curb and gutters, and ADA ramps was completed in most of the locations.

Overnight road work with alternating lane closures will continue from Del Monte Avenue to State Route 1 from 8 pm to 5 am. This work consists of grinding, resurfacing and paving. After completing paving, the electrical work will begin to install traffic signals control loops. Striping work will take place to then apply the final stripe configuration.

All businesses remain open and Caltrans appreciates the patience of the business community and the people of Castroville.

A zone for construction workers and two-way traffic will be maintained with minor delays and will include heavy equipment. During some stages of construction, there will be a temporary removal of parking, sidewalk and driveway access. Pedestrian access to local businesses and residences will be provided and maintained by the Contractor. Bicyclists and motorists are encouraged to share the road on SR 183. Travelers can expect delays of up to 15 minutes during peak periods. Plan your travel accordingly. 

Message and directional signs will direct travelers in advance of the project area.
