Striping Program

There is a potential the 11th edition of the Manual on Uniform Traffic Control Devices (MUTCD), when released, will require all edgeline markings to be a minimum of 6”, which will be an increase from the current 4” minimum. This will significantly impact Missouri Department of Transportation (MoDOT) given MoDOT pavement marking program far exceeds MUTCD requirements. With current staffing and equipment levels and a reduction of over 12,000 miles of striping production per year (due to increased refilling of paint, etc.), MoDOT would need to discontinue applying centerline markings on its 12,500 miles of low volume roadways in order to increase the width of the edgelines on the 15,500 miles of two-lane roadways which now get edgelines. Overall, MoDOT needs information to help determine what direction to take in response to the likely federal rule change that would result in no safety impact or a safety improvement.
