Caltrans will begin an operational improvement project to reduce conflict points at four at-grade median intersections along US 101 between Los Berros Road in Nipomo and Traffic Way near Arroyo Grande beginning on Monday night, May 13.

This project will eliminate left-turn movements from US 101 onto and from El Campo Road, Tower Grove Drive and at two additional median crossover locations. Roadwork is planned only in the highway median so access to all local businesses and residences will be maintained.

Motorists will encounter lane closures along northbound US 101 weeknights during the overnight hours from 7 p.m. to 6 a.m. and southbound from 8 p.m. to 5:30 a.m. Median access will be maintained for emergency responders at Hemi Road and Telephone Road (between El Campo and Los Berros Road).

“We are pleased with how quickly Caltrans is working to restrict left turn access at these four at-grade intersections on U.S. Highway 101. SLOCOG looks forward to the continued collaboration among state, regional, county, and city agencies that got us to this point, as it will be essential to developing a long-term solution for this section of the 101-corridor,” said SLOCOG Executive Director Peter Rodgers.

The contractor for this $250,000 project is Papich Construction of Arroyo Grande, CA. It’s scheduled to be complete by the end of May.

This project represents a cooperative effort between Caltrans, the City of Arroyo Grande, San Luis Obispo County, the San Luis Obispo Council of Governments (SLOCOG) and the California Highway Patrol (CHP) to improve operations along the corridor.

Caltrans reminds motorists to move over and slow down when driving through highway construction zones.
