how many miles of road in Maine

[luckyleftyme2]

The State of Maine has 23,450 miles of public roadway, more miles per person than any other
New England state. As a rural state, we have a relatively high per-resident cost for transportation
maintenance and infrastructure. MaineDOT maintains approximately 4150 centerline miles in
winter, 18% of the total roadway, which it divides into three categories of priority. The Maine
Turnpike Authority maintains 109 centerline miles. The remainder of the mileage is maintained
by Maine’s municipalities and counties. Maine’s 488 municipalities, 10 counties, and 3
reservations have winter road maintenance responsibility for approximately 81% of the total road
mileage. We estimate that clearing winter roads last year cost Maine (MaineDOT, MTA,
municipal governments) $98 million dollars, or $76 per person. Change in winter road
maintenance practices may provide an opportunity for cost savings. Any changes will need to be
balanced with levels of service that the public has come to expect.
By far the most widely used chemical on winter roads in Maine is rock salt!
