U.S. 66 and U.S. 91 divide in downtown Barstow, at the intersection of Business Loop I-15/Main Street and First Avenue. This view looks north on First Avenue after the U.S. 66/Main Street intersection. Heading north out of downtown Barstow, U.S. 91 immediately crosses the rail yard at Barstow via the Old Iron Bridge, which opened on April 26, 1930. This bridge had to accommodate an ever-expanding rail yard as train operations continued to grow. Today, trains constantly flow through town, making Barstow a hub of rail activity. After leaving the truss section of the Old Iron Bridge, old U.S. 91 turns northeast toward the Harvey House and old railroad depot. The Mojave River bridge comes into view in the distance.
