Infrastructure
Improvement Award: To Missouri Department of Transportation for System-Wide
Installation of Median Cable Barrier
Through an analysis
of the state’s crash data, Missouri Department of Transportation
recognized an emerging problem of severe cross-median crashes on its
most heavily traveled roadways. To address this safety concern, Missouri
began an effort to install median cable barriers system-wide on its
major interstates. The key to the success of this system-wide improvement
was the installation of low-cost safety devices across the entire system
-- even at locations without a history of severe crashes.
Cable barrier has
performed successfully in Missouri, catching over 95% of vehicles entering
the median. Most importantly, it is saving lives. As an example, Interstate
70 suffered 24 cross-median fatalities in 2002. The installation of
system-wide cable barrier since then has virtually eliminated this crash
type, as only two cross-median fatalities occurred in 2006, a decrease
directly attributable to the state’s system-wide approach to this
safety problem.
