About

​Roadway departure crashes and fatalities are a serious and often preventable problem. 66% of fatal crashes in Oregon are due to road departure and we are focusing on installing rumble strips in our shoulders and centerlines in order to reduce that number.

In 2021, we installed approximately 400 miles of rumble strips across 17 highways in the Portland metro area.  These important safety treatments significantly reduce fatal crashes on highways when drivers inadvertently depart their travel lane.  The locations of the rumble strips were chosen based on where documented safety concerns and crashes occur.

Rumble strips are grooved patterns installed in the center and shoulder of highways that create noise and vibration when driven over by a cars.  This alert immediately warns drivers that they are veering from their driving lane.  Rumble strips allow drivers to self-correct, return to their lane and avoid a crash. Shoulder rumble strips are used to reduce run-off-road crashes. Centerline rumble strips are used to reduce head-on and side-swipe crashes.

We primarily installed mumble strips - a new design of rumble strips - that uses a different wave pattern and still provides sufficient warning to drivers of lane departure, but with reduced roadside noise.  Mumble strips aren’t as disruptive to adjacent neighbors who may hear the noise generated by drivers hitting the grooved pavement.

Rumble strips will have gaps at intersections, interchanges, across on- and off-ramps and across bridges.  The strips are installed in a bike-friendly gap pattern along the shoulders.  Shoulder rumble strips are only installed where there is adequate shoulder width to accommodate a bike rider comfortably (four feet or more).

Locations of new rumble strips
Below are the locations of new shoulder rumble strips.  There will be gaps in these locations at interchanges, across on- and off-ramps and across bridges.

  • I-84 from I-5 to I-205 
  • I-84 from the Troutdale exit to the Sandy River Bridge
  • I-205 from I-5 to 10th Street
