Old Trails Bridge

Old Trails Bridge is a steel arch bridge spanning the Colorado River between California and Arizona, with a central curved section forming its main structural element. The structure combines multiple steel framework components that work together to carry traffic across the river.

The bridge was completed in 1914 and underwent significant modification in 1928 to enhance its capacity. By 1947, it transitioned to a new purpose, no longer serving as a regular crossing for vehicles on the main highway route.

The bridge gained fame as a backdrop in classic American films that captured stories of families traveling westward during hard times. Its appearance in these movies made it a recognizable symbol of that era's journey and struggle.

The bridge is best viewed from Interstate 40, particularly near the Park Moabi exit, which serves as the final California exit when heading eastbound. The viewing area is accessible directly from the main highway without requiring special detours.

At the time it was built, this was the longest arch bridge in America, created using an innovative cantilever construction method that was groundbreaking for that era. The engineering approach used here became an important reference for later bridge designs across the country.
