Hesperia, CA – Caltrans has announced that the opening of the temporary bypass road on Highway 138 near Hog Ranch Creek Bridge has been delayed until further notice due to the series of weather systems moving through the area.

It’s all part of  the $23 million Highway 138 East Alignment Project that will eliminate the switchbacks just east of Interstate 15.

Once Skanska personnel can complete the temporary pavement, Highway 138 motorists will be directed onto the bypass that will be utilized until the completion of the project, according to a Caltrans press release.

The state transportation agency explains that once the bypass opens flaggers and advanced warning signs will be in place to alert the traveling public of the new traffic configuration.

The project realigns the Highway 138, constructs outside shoulders and three wildlife crossings near Hesperia from 1.9 miles east of I-15 to 0.1 mile west of Summit Post Office Road.

The realignment project — which is scheduled for completion in summer 2018 — will also shorten the trip from Crestline to I-15 by nearly a mile.

The Highway 138 project is located outside the designated critical habitat for the federally-listed endangered Arroyo Toad (Anaxyrus Californicus).

The road through Summit Valley will a remain a two-lane road with one lane in each direction. The project will construct full 12-foot lanes in each direction, plus full shoulders of 8 to 10-feet each.

The contractor will also build three (3) new bridges requiring the excavation of 1,160 cubic yards of stream bank and placement of 2,657 cubic yards of rock slope protection within the streambeds. A total of 11 new culverts will be installed and 15 existing culverts will be removed.

Skanska will excavate about 777,000 cubic yards of dirt, traverse seven (7) tributaries of Crowder Creek, which is a tributary to Lytle Creek and ultimately the Santa Ana River, to build the “new” roadway closer to the existing railroad tracks.
