Multi-car pileups in three states on a snowy Monday injured more than 20 people and temporarily shut major highways.
Police say eight people were hurt in a 41-vehicle pileup that shut southbound Interstate 75 for hours when scattered snow showers pelted northern Kentucky.
Kentucky's Kenton County police department said six of the injured were taken to hospitals, but none of the injuries was life-threatening. It said cars and other vehicles collided on southbound lanes just south of Cincinnati.
Police say 23 vehicles had to be towed before southbound lanes reopened. A news photo showed cars sprawled across several lanes and beside a shoulder with accumulated snow. Authorities say the cause is under investigation.
Authorities in western Pennsylvania are blaming a snow squall for a 21-car pileup that closed Interstate 80 for about eight hours.
The eastbound lanes reopened late Monday night after crews cleaned up the crash involving six tractor-trailers and 15 other vehicles in Washington Township, Jefferson County.
Seventeen people were reported injured. State police say several of those injured were in serious condition.
Jefferson County Emergency Management Director Tracy Zents tells WJAC-TV a tanker carrying liquid nitrogen was involved in the crash but no spill occurred.
And a burst of snow across central Indiana on Monday caused multicar-pileups that temporarily closed three major highways around Indianapolis.
A 12-vehicle crash closed all eastbound lanes of Interstate 70 on the city's east side. Crashes also closed the eastbound lanes of Interstate 465 on the south side and southbound lanes of Interstate 65 just south of the city.
All three highways opened to traffic again later Monday afternoon, state police said.
State Police Sgt. Rich Myers said troopers worked more than 80 crashes around Indianapolis over about four hours. No serious injuries were reported.
