Roads & Bridges

Roads
Miles of public road (including boundary roads): 2,232

Pavement Condition (in Lane Miles)
Note: Poor pavements are generally in need of rehabilitation or full reconstruction to return to good condition. Fair pavements are in need of capital preventive maintenance to avoid deteriorating to the poor classification. Good pavements generally receive only routine maintenance, such as street sweeping and snow removal, until they deteriorate to the fair condition.
