The Maine Department of Transportation has been installing rumble strips on the centerline of roads since 2006. These centerline rumble strips have proven effective both in Maine and nationwide at keeping drivers from crossing the centerline and having a potential head on crash. 

Initially, the Department was taking a reactive approach to the installation. If they could identify a higher frequency of head on crashes within a given corridor, then rumble strips were considered. More recently, they have taken a systemic approach to identify potential corridors that have similar characteristics where head on crashes occur in Maine. The majority of our head on crashes were taking place on Corridor Priority 1 & 2 roadways with Average Annual Daily Traffic (AADT) above 6000 cars per day, and where speed limits were generally 45 mph and above. MaineDOT has been able to place rumble strips on most of these roadways and now looks to expand to other higher speed corridors with lower traffic volumes where the Department believes rumble strips would be a safety benefit for users.

The most evident complaint about centerline rumble strips since they began placing them is the noise created when a vehicle runs on them, especially a larger vehicle such as a logging truck or tractor trailer. The safety benefits from the rumble strips, nearly a 90% reduction in fatalities in Maine, caused MaineDOT to study options to limit noise. They are happy to be installing a new centerline rumble strip that is not as deep as the previous design. It is sinusoidal in shape and still gives the benefits of alerting the distracted driver without the noise that could be previously heard from vehicles traveling on the centerline.

Below are MaineDOT's planned routes. In some instances, they will simply be replacing existing rumble strips after a completed paving project. Centerline rumble strips are planned for Lincoln later this summer at the following locations:

  • Route 2, Passadumkeag - Lincoln: Beginning at the pavement joint near Madden Timberland Inc. and continuing 12.47 miles to the 35 mph sign south of Penobscot Valley Avenue.
  • Route 2, Lincoln: Beginning at the 45 mph sign north of VFW Drive and continuing 4.04 miles to the Lincoln/Winn town line.
  • Route 6: Beginning at the 45 mph sign north of Evergreen Drive and continuing 7.14 miles to the pavement joint at the Lincoln/Lee town line.
