State Department of Transportation anti-icing crews treated Interstate 290 in Worcester with a mixture of salt and brine at 5:45 a.m. Sunday, about an hour before icy road conditions triggered a chain reaction crash there that ultimately involved 65 vehicles, including three tractor-trailers, officials said.
DOT spokesman Michael Verseckes said today that the DOT activated its anti-icing forces in Central Massachusetts around 2:30 a.m. Sunday in response to weather forecasts. The DOT focused its attention in the southern corner of the county, and not on the stretch of I-290 where the crashes occurred, said Verseckes.
