We have been told that the concrete barrier on the turnpike in Kansas saves around 15 lives per year. Three young adults were just killed on I-70 in Missouri after being run off the road into oncoming traffic. Chances are a median barrier would have saved their lives. Please write your congress person and tell them you want median barriers on all the roads. There was a crash recently at I-435 and Roe in Overland Park, KS where rumble strips would most likely have saved John and Sara's lives .
Rumble strips are a cheap way to save lives.
One Secretary of Transportation told us that people do not run off the road in metropolitan areas. It is too bad John and Sara above are not around to answer this comment. Maybe someday we will have leaders that understand what it is like to lose loved ones with substandard engineering. The maximum legal drop off from the shoulder of the road is 6 inches down and 12 inches out from the edge of shoulder. If there is too large a drop off on the shoulder it makes almost impossible for the vehicle to recover.
