The SR-138 Widening and Railroad Safety Project

The SR-138 Widening and Railroad Safety Project scope’s goal includes necessary improvements to the intersection of Palmdale Boulevard and Sierra Highway. The project will improve railroad crossing safety by reconfiguring the railroad signal mast-arms and other rail equipment to meet current standards. This project is intended to provide flexibility for future expansion as needed, allowing agencies such as California Department of Transportation (CalTrans), California High Speed Rail (CHSR), or the City of Palmdale, to easily provide the capacity improvements at a later date, such as a road widening or grade separation project.

The project schedule is outlined in the table below, and includes time to complete the Plans, Specifications and Estimates, coordinate with Union Pacific Railroad (UPPR) and MetroLink, advertise and award the project through Planetbids, and construct the infrastructure improvements.
