OVERNIGHT AND DAYTIME WORK CONTINUES ON STATE ROUTE 183/MERRITT STREET IN CASTROVILLE

MONTEREY COUNTY — Construction continues on a major rehabilitation of State Route 183 (Merritt Street) in Castroville to enhance multimodal travel. This next stage of work will result in daytime and nighttime sidewalk, curb and gutter, driveways, ADA curb ramps and roadway work.

One lane of traffic in each direction will remain open for travelers on SR 183. Work next week includes saw cutting, demolition of existing sidewalks, curb and gutter, installing underground irrigation and utility boxes. The contractor will also continue paving local roads intersecting Merritt Street along the northbound lane.

Construction activities next week will take place between 7 am to 4 pm in the locations from Rico Street to Preston Street and from Sanchez Street to Washington Street.

Overnight road work with one-way reversing traffic control is scheduled on State Route 183 on Monday night, April 6 through Thursday night, April 9 between Rico Street to Preston Street and Sanchez Street to Washington Street from 8 pm to 5 am.

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

Residents in the vicinity of this work should expect pavement striping and equipment adjacent to live traffic. This is crucial for the safety of both workers and all travelers.

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

Travelers are encouraged to follow directions provided by construction and traffic signs within and around the construction areas and to be alert for highway worker and equipment in this work zone.

All businesses in the Castroville Business District on State Route 183 Merritt Street remain open.
