What is the Florida Intrastate Highway System (FIHS)?
A. The FIHS is a statewide transportation network that provides for high-speed and high-volume traffic movements within the State of Florida. The FIHS is composed of interconnected roadway corridors such as interstate highways, Florida’s Turnpike System and regional roadway corridors like SR 80 (Southern Boulevard). The primary function of this system is to serve interstate and regional commerce and long distance trips to move people and goods throughout Florida. The FIHS carries 30% of the total traffic on only 3% of Florida’s roads. Visit the FDOT website for additional information regarding Florida’s Intrastate Highway System.
