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 the state of Florida's highway lane miles in thousands (K). The State Highway System is comprised of interstates, turnpikes, and all other roads under the jurisdiction of the state of Florida. Lane miles are the product of centerline miles and the number of lanes on the road. This indicator’s data source is the Florida Department of Transportation's State Highway System Mileage Report and is updated annually with six to seven months lag time.
