Guard Cable

Hundreds of lives have been saved with the installation of more than 800 miles of guard cable on Missouri's busiest highways - Interstates 70, 44, 29, 35, 55, 49, 64 and 435 and Routes 36, 63 and 67.

Median guard cable, consisting of three strands of steel cable, is designed to "catch" a vehicle before it crosses into the opposing traffic lanes, bringing it to a stop before it hits other vehicles. It's generally used where medians are 60 feet wide or less.

Since the cable’s installation, cross-median fatalities have decreased on interstates from approximately 50 a year down to less than 10.

Studies have shown that guard cable has prevented vehicles from going into opposing lanes over 95 percent of the time.

With the completion of guard cable installation on I-70 and I-44, cross-median fatalities have been reduced to 1-3 per year on these vital routes.

The American Society of Civil Engineers cited the success of Missouri's median guard cables in reducing highway deaths in its 2009 Report Card for America's Infrastructure.
