I-595 Corridor Improvements

The I-595 Express Corridor Improvements is one of the largest transportation projects contracted with the Florida Department of Transportation (FDOT) and is also FDOT’s first public-private partnership (P3) project and the first availability payment in the United States. The 10.5-mile corridor was widened and expanded from the I-75/Sawgrass Expressway interchange to the I-595/I-95 interchange. The $1.23-billion improvements included the addition of auxiliary lanes, bypass and braided ramps, collector-distributor roadways, and a tolled reversible express lanes system with a direct connection to Florida’s Turnpike. The reversible express lanes are tolled at varying rates throughout the day to provide for the continual free flow of traffic.
