Compared to historical trends, new roadway construction is slowing. Much 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 and 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.

This indicator shows Florida public roads centerline miles in thousands (K). A centerline mile is the length of road in miles. Public roads are comprised of different categories based on their functions: interstates, principal arterial, minor arterial, major and minor collector, and local in both urban and rural category.
