Can Interstate Cable Barriers Be Improved?

The first time I saw the cable barriers as I was driving down I-64 my only thought was that they were absolutely hideous. I admit that I was skeptical about how effective the cable barriers would be. I wasn’t sure they would stop any accidents that concrete barriers wouldn’t stop. Would the cable carriers really prevent a cross over accident? Would there be problems with emergency vehicles getting to the accident scene because they couldn’t get through the median? I had questions but I was wrong.
There are now 51 miles of cable barriers in Jefferson County, Kentucky at a cost of $130,000.00 per mile. From 2006 until August of this year these barriers have been hit 609 times. These barriers cover all of I-265 and I-64 from downtown to the Watterson. There are also barriers in Bullitt County as well as Floyd and Clark Counties in Indiana. Law enforcement officer estimate that the barriers have saved 100s of lives.
The cable barriers have several benefits over concrete barriers:
· They are significantly less expensive at $130,000.00 per mile as compared to $400,000.00 per mile for concrete barriers.
· Cars that hit the barriers often get stuck between the cables and do not rebound back into traffic.
· They absorb the energy of impact helping to minimize the severity of some injuries.
There are those that believe that all Kentucky interstates should be built with cable barriers. What do you think? If they save lives I am for it. There are plans for additional cable barriers in Kentucky, but unfortunately there is no money allocated for the Louisville Metro area.
There are groups who oppose cable barriers, such as most motorcyclists. Jay Huber, the president of the Kentucky Motorcycle Association/Kentucky Bikers Association, calls the cable barriers “a cheese slicer”. This is something I hadn’t considered. How would a barrier made of cables stop an out of control motorcycle? I can see that these barriers are potentially dangerous and deadly to the rider causing deadly motorcycle accidents.
Huber believes that the installation of nylon straps or mesh over the cables would reduce this danger. There is opposition to this addition. The stance against this safety measure is the additional cost of installation. Additionally there have been no motorcyclists seriously injured or killed due to striking the cable barriers. We spend enough money on foolish endeavors. Let’s make sure that the cable barriers are safe for everyone.
Another problem according to the Kentucky State Police is that the barriers prolong emergency vehicle response time. This doesn’t occur very often, but vehicles have had to travel an extra two to three miles to find a cut through to get to the accident scene.
I played golf last month with one of the supervisors of a construction crew that was installing cable barriers in southern Indiana. I asked him why they were not putting gaps every ¼ of a mile or so. He gave me two reasons:
1. The cost would be higher.
2. An out of control car would get through the gap and cross over into oncoming traffic.
I don’t believe that additional cost should be a consideration if the gaps put in would allow a quicker response by emergency vehicles and save even one life. I wonder how muck it would cost? My guess is not as much as the total cost of the concrete barriers. As to getting through the cross over gaps, I did not believe his answer. It seemed like a bunch of bull. If you make the gaps parallel to the highway and have overlapping sections for the gaps that are maybe 50 to 100 feet long an out of control car would not be able to cross over. There is just no way for it to get through.
The bottom line is that cable barriers have saved lives and will save more lives. Let’s make them better to make sure additional lives are saved.
