HESPERIA, CA. (Pain In The Pass) >> The Ranchero Road Widening Project in Hesperia is approximately a 5 mile stretch of road. Construction could start as early as February.

The widening project on Ranchero Road which spans through San Bernardino County and parts of the City of Hesperia. This is the last project (Phases) of three. The other two improvements that have occurred along Ranchero Road over several years. The Railroad under-crossing bridge by Santa Fe Ave. and the Interstate 15 Ranchero Rd bridge were the first two parts.

The widening project is planned for a 5-mile stretch of Ranchero Rd. from Mariposa Road to Seventh Avenue. They are planning to install new traffic signals whi h will be be placed at the intersections of Maple Ave., Cottonwood Ave. and Seventh Ave. Also they will replace the bridge over the California Aqueduct, and widening the railroad crossing by Oak Hills High School.

Construction is expected to start in February 2022, also noted that the project will be completed in phases “to minimize impacts to motorists.” Construction will start near Mariposa Rd. first then work towards Seventh Ave. Ranchero will be reduced to one lane in each direction throughout the project.

Beginning Summer of 2022 Ranchero will be closed at the aqueduct for about 6 to 9 months for a wider bridge. Detours will be posted. Mesquite Street is expected to be major part of the detour route. Public will be notified prior to road closures and detours.

No night roadwork unless it is an emergency.

The total cost of the project is estimated at $64.1 million, with the City of Hesperia responsible for $37 million.
