The Cold Spring Canyon Arch Bridge in the Santa Ynez Mountains links Santa Barbara, California with Santa Ynez, California. The bridge is signed as part of State Route 154.

It is currently the highest arch bridge in the U.S. state of California and among the highest bridges in the United States. At its highest point, the bridge deck is 400 ft (122 m) above the canyon floor. The bridge is also the largest steel arch bridge in the state. It was determined to be eligible for the National Register of Historic Places with exceptional significance.


The current bridge was completed and opened to traffic in February 1964. It was constructed by U.S Steel Corp's American Bridge division and Massman Construction Co. The structure won awards for engineering, design, and beauty. It was in the top 5 longest span arch bridges of this "supported deck" type in the world until the 1990s.

Cold Spring Tavern, originally a stagecoach stop, is approximately 600m south of the bridge's west base in the canyon below, on a stub of Old San Marcos Pass Road (now named Stagecoach Rd.) connecting with SR 154 at Camino Cielo and Paradise Roads.

Seismic retrofitting was completed in 1998 by American Bridge, one of the companies involved in the original construction.
