The state Department of Transportation announced Monday that crashes decreased overall at 33 intersections replaced with roundabouts.

PennDOT compiled crash data using 33 roundabouts in 18 counties, including the ones in Cranberry and Clinton townships in Butler County, according to a PennDOT news release.

“We continue to see that Pennsylvania’s roundabouts save lives and reduce crash severity,” said Yassmin Gramian, PennDOT secretary. “While they aren’t the right option in every intersection, we’re pleased that they help to make our roadways safer.”

The 33 roundabouts studied are on state roads at intersections previously controlled by stop signs or signals.

The roundabouts chosen had at least three years of crash data available before they were built.
