Recently the TXDOT installed many mile of the cable barrier system on the hwy's I travel every day. This hwy is between Dallas and Commerce (a small college town). I figure there must have been so many complants about the number of young people killed by cross-overs. Now that they have completed the install, it has not lasted a year and the highway is going with the perminent concrete barrier. It think it must be due to maintenance/repairs. It is really easy to see the impact the cable barriers have made. There is not one full mile that was not hit and in need of repair, and that's out of 40 plus mile of cable barrier. They do seem to fix it fast, but it sure must cost them. I think it is the great thing they could have done!
