Highway 101 improvement project in San Miguel continues next week 

–A project to improve six miles of US Highway 101 from San Miguel to Camp Roberts will continue with the closure of the No. 1 (left) southbound lane of US 101 at the San Marcos Road Intersection beginning Monday, April 15.

As a result, motorists traveling northbound will be detoured onto the southbound lane of the San Marcos Overcrossing beginning Tuesday, April 23. This traffic switch is expected to last until the end of August.

The northbound US 101 left turn pocket at San Marcos Road will be closed on Monday, April 15 at 6 a.m. until Tuesday, April 23 at 4 p.m. to facilitate this traffic switch. Motorists headed northbound may detour at Wellsona Road.

In addition, the northbound US 101 off-ramp at South Mission Street will be closed beginning Tuesday, April 23 until early this summer. Motorist may detour to the next off-ramp at 10th Street.

The southbound on-ramp to US 101 at South Mission Street remains closed. Motorists may detour via 10th Street, south to Cemetery Road before re-entering US 101 via the southbound on-ramp.

This project includes a realignment of US 101 to accommodate a new right hand southbound on-ramp at South Mission Street, paving US 101 and nearby ramps and lowering the profile of US 101 at Camp Roberts to achieve a minimum bridge clearance height. Drainage systems, guardrail and lighting will also be improved within this corridor.

The contractor for this $53 million project is Security Paving of Sylmar, CA. It’s scheduled to be complete in the Spring of 2020. The public may learn more about these highway upgrades on the Caltrans District 5 Projects page:
