Starting just before 7 a.m., Sixty one cars, two trailer trucks and two six-wheel trucks collided in Worcester, Mass., creating a 1,500 foot long chain of impacted vehicles, according to Massachusetts State Police.
Recovery teams were delayed in getting to the stretch of Route 290 to treat the 35 injured people because the road had not been sufficiently salted yet.
A man and a woman, both in their thirties, were seriously injured, but their specific conditions were unknown, police said.
Sixty additional people were bused away from the scene, Massachusetts State Police said.
Trooper Erin McLaughlin observed the crash on her way to another crash and tried to prevent further damage by yelling "look out" to drivers. Her police cruiser was rear-ended during her efforts.
State Police warned residents from their Twitter account, "Roads are slick in central Mass, Worcester Cty area. If you don't have to go out, wait!"
