MoDOT's Rumble Strip policy - the details

Headlines are quick hits from media outlets from Missouri and around the world. Follow the headline link for the full story. The source of this headline says:

Edgeline rumble strips are used to enhance safety on every paved shoulder at least 2 ft. wide, unless the shoulder has a curbed section or is intended to be used as a future travel lane. Rumble strips are omitted where the posted speed is less than 50 mph. All major roads will have edgeline rumble strips unless the posted speed is less than 50 mph.

In most situations, edgeline pavement marking material is sprayed over the milled rumble strip, creating what is referred to as a “rumble stripe.”

MoDOT's Rumble Strip policy - the details

MoBikeFed comment: This document is MoDOT complete rumble strip policy: What roads are they installed on--and not installed on--how wide, where on the road, when centerline, when edgeline, and when both, how wide must the shoulder be, and all the rest of the details.

You may know that MoBikeFed and other cycling groups worked with MoDOT in the mid 2000s to improve the rumble strip policy. Previously roads with wide, beautiful, very bicycleable shoulders had wide rumble strips placed right in the middle of the shoulder--usually ruining the shoulder for bicycling.

Now MoDOT never installs that type of rumble strip--it is always narrow and under the white line.
