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.

Description

The department currently has a typical drawing CB6-4.3M3, for an un-reinforced Full F-Shape concrete barrier constructed by slip-form. The need for a typical drawing for an un-reinforced Half F-Shape barrier constructed by slip-form has arisen on a recent project. A new typical drawing has been developed by the department and is being issued under this Design Bulletin. The slip-formed Half F-shape concrete barrier shall be used with earth fills as shown on drawing CB6-4.3M3A. The earth fill provides lateral support for the Half F-Shape concrete barrier.
