State plans to add more rumble strips on Route 9 to improve safety

CONCORD - The state Department of Transportation is planning to extend rumble strips along more of "Death Alley," one of the nicknames for Route 9.

According to the Keene Sentinel, the project would include rumble strips along the centerline, passing lanes and shoulder from Chesterfield to Hillsboro - about 71 miles in all.

Rumble strips were added along seven miles of the road between Henniker and Hopkinton in 2008. The result was a 33 percent reduction in total crashes and many fewer fatalities, a 2013 study found.

Bill Cass, assistant commissioner for the N.H. DOT, said the project will go out to bid in February with construction on to be completed by the end of May. The total cost is estimated around $500,000.

“We know that everybody wants to have these out there, so we try an expedite these as much as possible,” saidRonald J. Grandmaison, project manager for the Bureau of Highway Design.

“The rumble strips are definitely a step in the right direction,” said N.H. State Police Lt. Joseph DiRusso. “Obviously we’ve had some pretty serious accidents over the past several years. And the majority of those involved operators driving over the center, some being distracted, some other unknown causes, but that’s the majority of the cause of the collision."
