The mission: to shoehorn three new 10.5-mile-long reversible toll lanes into the middle of a six-lane interstate highway—including work on 63 bridges and 2.5 miles of the Florida Turnpike—while minimizing disruptions to up to 200,000 daily vehicles in the Fort Lauderdale area of Broward County, Fla.
The method: a concessionaire agreement with a design-build construction contract, a first for the Florida Dept. of Transportation (FDOT). The $1.8-billion Interstate 595 widening project also came with plenty of complexity, including southern Florida's quirky geology, various stakeholders and an immovable canal that borders the project's alignment.
