Roundabouts are saving lives according to PennDOT data that reviewed 22 roundabouts in 19 locations - including ones in Allegheny Beaver, Butler, Erie and Washington counties.

The department says crash fatalities at the locations have been reduced 100% and the number of crashes have dropped by 24%. Serious injuries as a result of crashes are down by 78%.

"We continue to be encouraged by the safety advantages of the modern roundabout,” said PennDOT Secretary Yassmin Gramian. “Lives are being saved and injuries reduced. The data cannot be denied."
