State Route 138 Curve Correction

The State Route 138 Curve Correction project, identified by agreement EPIMS-SBR-63145-R6, is an infrastructure initiative led by the California Department of Transportation District 8 in San Bernardino County. The project focuses on the realignment of State Route 138 and the modification of drainage systems and streambeds along approximately one-half mile of the highway near Hesperia, specifically between Post Mile T16.20 and PM 16.97, extending from one mile east of Interstate 15 to just west of the Hog Ranch Creek Bridge. Key physical activities include the concrete lining of an existing culvert, the removal of an existing culvert with its associated headwalls, wingwalls, and cable railings, streambed grading, the installation of a new drainage system with headwalls and cable railings, and the placement of un-grouted rock slope protection. The project is governed by Fish and Game Code section 1602 and has been approved by the California Department of Fish and Wildlife. Environmental compliance has been established through a Mitigated Negative Declaration and Addendum under CEQA, with the determination that the project will not have a significant environmental effect provided that specific mitigation measures are implemented as conditions of approval. Administrative oversight is managed by Adam Compton of Caltrans District 8 and Chris Briggs of the California Department of Fish and Wildlife. The project is classified under NAICS code 237310 for highway, street, and bridge construction.
