The money spent during the 2012-13 season eclipsed the $56 million spent during the 2010-11 winter.
The state averaged 20.8 inches of snow this winter compared to 44.4 inches in 2010-11.
DOT spokesman Steve Schapiro tells The Star-Ledger of Newark (http://bit.ly/10zAMtT ) the DOT responded to 37 events, including 24 that required a statewide mobilization.
Officials say nearly half of the money spent involved the 1,700 contractors who help the DOT plow and spread salt. Their average pay increased from $137.62 per truck per hour to $172.15.
The DOT spread nearly three times as much salt as last year.
