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 [[California State Route 154|State Route 154]].

It is currently the highest arch bridge in the U.S. state of California and among the [[List of bridges in the United States by height|highest bridges in the United States]]. At its highest point, the bridge deck is {{convert|400|ft|m|0|abbr=on}} above the canyon floor.<ref name=SYVN/><ref name=hb/> The bridge is also the largest steel arch bridge in the state.<ref name=":1">{{Cite news|last=Gagnoli|first=Giana|date=May 2, 2010|title=Cold Spring Canyon Bridge: By the Engineering Numbers|url=https://www.noozhawk.com/article/050210_cold_spring_canyon_bridge_numbers|access-date=June 6, 2020|website=Noozhawk|language=en}}</ref> It was determined to be eligible for the National Register of Historic Places with exceptional significance.<ref name=":1" />

==History==
The current bridge was completed and opened to traffic in February 1964.<ref>{{Cite web|title=Cold Spring Canyon Bridge, State Route (SR) 154 from Post Mile (PM) 22.95 to 23.19, just north of the San Marcos Pass, Santa Barbara, Santa Barbara County, CA|url=https://www.loc.gov/item/ca3902/|access-date=2020-06-08|website=Library of Congress}}</ref> It was constructed by [[U.S. Steel|U.S Steel Corp's]] American Bridge division and Massman Construction Co.<ref name=":1" /> The structure won awards for engineering, design, and beauty. It was in the top 5 longest span [[arch bridge]]s of this [[Timeline of three longest supported deck arch bridge spans|"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.

The bridge was designated as a Historic Civil Engineering Landmark by the [[American Society of Civil Engineers]] in 1976.<ref>{{cite news |author= |title=Bridge tamed a treacherous detour |url=https://lompocrecord.com/lifestyles/columnist/roadside_attractions/bridge-tamed-a-treacherous-detour/article_2d17a9fe-b9d0-11e1-820d-001a4bcf887a.html |work=[[Lompoc Record]] |date=June 19, 2012 |access-date=March 6, 2021}}</ref>

Seismic retrofitting was completed in 1998 by [[American Bridge Company|American Bridge]], one of the companies involved in the original construction.<ref name=":1" />

===Barriers===
{{As of |2012|March}}, the bridge had been the site of 55 suicides{{citation needed|date=November 2020}} since its completion, which is about one per year on average; however, some years have several more suicides, such as the eight deaths recorded in 2009. In an effort to prevent future incidents, [[California Department of Transportation]] installed a {{convert|9.5|ft|m|abbr=on}} tall barrier in the form of an inwardly-curved, finely-gridded mesh fence in March 2012.<ref>
