A Redding Caltrans crew lifts high tension cables into a replacement post after an accident destroyed the old support.
The California Department of Transportation in District 2 has made available a video explaining the benefits of cable median barrier on its webpage at www.caltrans2.info. The video (see below for a shorter version) explains how the cable median barrier works, is installed, and repaired.
High tension cable barrier was originally installed in 2009 in the median of I-5 in two segments. Segment one is from Deschutes Road to one mile south of Knighton Road. Segment two is from Bonnyview Road to the Hilltop Drive Overcrossing.
Since the installation of the barrier in 2009, an estimated 60 vehicles have impacted the barrier. This barrier has done an exceptional job of safely redirecting errant vehicles and virtually eliminating cross-median accidents. Of the 60 collisions, only one injury has been reported.
A safety project is currently under construction to install cable median barrier on a four-mile section of I-5 from 1.3 miles south of Knighton Road to 0.5 miles north of Smith Road. This project is similar to the two sections of barrier previously installed on I-5 and will also include earthwork to flatten the existing median and improvements to drainage.
The $1.4 million project is anticipated to be complete in the fall of 2011.
