A project to enhance drainage facilities on Highway 1, from two miles north of the U.S. 101/State Route 154 separation to just north of Union Valley Parkway, will begin Monday, May 5, creating some delays.

Travelers will encounter a southbound lane closure next week between Los Alamos and Orcutt from 7 a.m.-7 p.m. Delays should not exceed 10 minutes.

Lane closures will also occur 7 a.m.-7 p.m. Monday, May 15 and Tuesday, May 16 to allow for placement of a protective barrier.

Most of this work will occur on the shoulders behind k-rail, but travelers will encounter intermittent lane closures during this project for the placement of protective barrier, according to Caltrans.

The project will rehabilitate drainage systems at 11 locations by providing repairs and improvements to extend the service life of the existing culvert systems, Caltrans said.

In addition, existing lighting systems will be replaced, and lighting will be added at three locations near Los Alamos. Transportation Management System replacements will include traffic loops and microwave radar sensor.

The project is expected to be complete in December.

Contractor for the $3.3 million project is CCFG Construction from Sonora, California.
