North First Avenue Bridge Over BNSF Railroad Project

The San Bernardino County Transportation Authority (SBCTA), in cooperation with the City of Barstow and Burlington Northern Santa Fe (BNSF) Railroad, is leading the construction effort to replace the existing North First Avenue bridge over a BNSF railyard. The bridge was built around 1930 and during the Bridge Inspection Report prepared by Caltrans in April 2012, the bridge Sufficiency Rating (SR) was 3 out of 100. The existing bridge is considered Structurally Deficient (SD) in its superstructure, substructure, and the overall structural evaluation. The existing bridge is also considered Functionally Obsolete (FO) due to its overall geometry and substandard vertical clearance.

The project includes the construction of new approach roadways, a new 2-lane structure, and the demolition of the old structure once the new facility has been opened to traffic. The replacement structure will provide safety benefits and accommodate all legal truck and permit vehicles, provide standard 8-foot shoulder widths, and one 8-foot sidewalk.
