Crews have begun work to replace a culvert just outside of San Luis Obispo city limits in a project that will last through Thursday.
A section of Orcutt Rd. is blocked off north of Biddle Ranch Rd. between Righetti Rd. and the San Luis Obispo city limit.
The road will be closed to drivers from 7 a.m. to 4 p.m. from Sept. 20-22.
There are more than 4,950 culverts in San Luis Obispo County. The culvert up for replacement was found to be deficient in a recent inspection, city officials say.
Detour signs will be in place while the road is closed.
