With the state suffering through its second arctic cold front and a third predicted for early February, the Tennessee Department of Transportation has plenty of salt reserves in an effort to keep the roads clear.“So far, we are doing just fine,” said TDOT spokesperson Jennifer Flynn. “After nearly running out of salt in 2010, we increased our snow and ice budget and increased our salt suppliers from one to three.”TDOT’s statewide 2013-14 winter weather budget is $19.7 million, and includes salt, salt brine, overtime for employees, and equipment maintenance. The department’s three salt vendors refill salt bins in all 95 Tennessee counties.In December 2013, TDOT had more than 235,000 tons of salt and more than 1.8 million gallons of salt brine ready for use.
