– Construction on the widening of Highway 46 East in the Cholame area will require a three-day, daytime full closure of State Route 41 from the interchange with Highway 46 East to State Route 33 beginning Tuesday, Aug. 26 through Thursday, Aug. 28 from 6 a.m. to 8 p.m., according to a press release from Cal Trans District 5.
Travelers headed east on Highway 46 will continue to State Route 33 before reaching State Route 41 at Reef Station. Travelers headed south on State Route 41 will detour onto State Route 33 at Reef Station to Highway 46 East. Delays are not expected to exceed 45 minutes.
The closure will allow the new Highway 46 East/State Route 41 interchange to be connected to State Route 41.
The full widening project is expected to be complete in spring of 2026. All businesses near the Highway 46 East corridor remain open. The contractor for the $147 million project, which extends from west of Davis Road to west of Antelope Road, is Atkinson Construction of Irvine, Calif.

The $47 million widening from McMillan Canyon Road to Lucy Brown Road was completed in 2019. The $38 million widening from Almond Drive to McMillan Canyon Road was completed in 2016. The $54 million widening from Geneseo Road to east of Almond Drive was completed in 2014, and the $30 million widening from Airport Road to Geneseo Road was completed in 2010.
