Several people have commented about the new mile marker signs along I-55 and I-57 and have wondered why MoDOT is wasting money putting new mile markers up every 2/10 of a mile.
The new signs will replace the two signs that are currently alongside our interstate highways. The first sign being replaced is the mile marker sign that is located every mile along the highways. The other "sign" being replaced is the white plastic delineator that is placed every 1/10 of a mile. New signs indicate the direction of travel, the interstate number and the mile number in 2/10 mile increments.
The single new markers which replace the two older markers are estimated to save approximately $200,000 a year in maintenance costs. Life expectancy of the new signs is about 10 years. The primary reason for the replacement is to provide accurate location information for motorists. If a motorist has an accident, flat tire, or some emergency problem, they will now be able to say "I am on southbound I-55 at the 37.8 mile marker" when reporting their situation to either the state patrol, local police, or when calling 911.
Emergency vehicles will be able to be directed to an exact location. The new signs will be particularly beneficial to ambulance and helicopter responders.
