SR-118 Arroyo Simi Safety Fence
Install bridge safety barrier systems
Project Description
Location and Limits:
Ventura County, City of Moorpark, Post miles 18.4 through 18.8
Background:
This half-mile project will install suicide prevention systems along the Arroyo Simi Overhead Bridges on the northbound and southbound directions of State Route 118 (SR-118) in Ventura County.
California Highway Patrol and the Ventura County Sheriff Department have identified more than 20 people have attempted or committed suicide on the Arroyo Simi Overhead Bridge since 1994, with majority occurring since 2009. The City of Moorpark and Ventura County communities have expressed concern about the potential of higher rates of suicides incidents, prompting a request for construction of a prevention system.
In 2017, Caltrans met with mental health professionals from multiple agencies including Didi Hirsch Mental Health Services, a nonprofit agency that provides mental health, substance abuse and suicide prevention services to Southern California communities, to discuss how to best minimize the risk of suicide attempts along the Arroyo Simi Bridge. In June of 2018, Caltrans began the prevention process, installing more than a dozen bilingual suicide-prevention signs line the overpass that connects SR- 23 to SR-118.
The Bridge Safety Barrier System:
The scope of work will install a suicide prevention barrier system along the Arroyo Simi Overhead Bridge on SR-118 on the Northbound and Southbound sides. The project will install more than 6,400 linear feet of safety fence along the Arroyo Simi Overhead Bridge.
The project purpose is to improve the safety along the Arroyo Simi Overhead Bridge.
