Description

This Bulletin is issued to inform practitioners of the department’s guidelines on the use of High Tension Cable Barrier (HTCB) installed in the median and on the roadside (or right hand side in the direction of travel) of the roadway. Cable barrier has been proven to effectively prevent or reduce the severity of median cross over crashes and run-off-road crashes. HTCB installed at median and roadside locations has been shown to be the most forgiving barrier system available for reducing the severity of run-off-road crashes in many applications.
