SR-138 East Realignment Project
EA 0Q3004, ID: 08000201914

The California Department of Transportation (CALTRANS) proposes to realign and re-construct the 2-lane paved section with shoulders, 3 wildlife crossings and off highway vehicle crossing.

Project Description & Scope

The project will realign the roadway, construct outside shoulders and three wildlife crossings on State Route 138 (SR-138) near Hesperia from 1.9 miles east of Interstate 15 to 0.1 mile west of Post Office Road.

Need & Purpose of Project

The existing highway configuration has many nonstandard horizontal and vertical curves and grades as steep as 15%. The existing pavement is between 21 and 28 feet in width, no paved shoulders and narrow or nonexistent earth shoulders. This project will improve operational efficiency by taking out some of the curves and steep grades, widen existing lanes to 12 feet, and add eight foot shoulders.

Estimated Construction Cost

$23 Million
