Road Mileage



Some of the indicators shown in this section are: lane miles on State Highway System, centerline miles and lane miles on all Florida public roads. These indicators will be updated annually as the reports become available. This usually occurs about six months after the end of the year. Centerline miles refers to the length of the road in miles. Lane miles are the product of centerline miles and the number of lanes.


Compared to historical trends, new roadway construction is slowing . Most construction work is roadway rehabilitation and/or widening. The new lane miles add capacity and attempt to improve driving conditions for Florida’s motorists.


The Federal Highway Administration reports the number of centerline miles and lane miles annually. The Highway Statistics Series is available online at http://www.fhwa.dot.gov/ohim/ohimstat.htm. This resource lists the mileage by ownership or functional classification.


The Florida Department of Transportation’s Transportation Statistics Office also gathers and reports roadway mileage twice per year. The number of miles is available by road classification, such as - interstate, toll roads, etc. For more information on highway infrastructure, visit http://www.dot.state.fl.us/planning/statistics/#resources.
