The I-595 Corridor Improvement Project is one of South Florida’s most important transport infrastructure developments and was the first Public-Private Partnership (PPP) undertaken by the Florida Department of Transportation.
The project involved the upgrade and expansion of 16.9 km of motorway, including the reconstruction of I-595 and SR-84, the implementation of dynamically tolled reversible express lanes and major improvements to interchanges and access infrastructure.
It also included 53 new bridges (969,000 ft² of new deck), bridge and interchange reconstruction, seven braided ramps to avoid traffic weaving, twenty-nine entrance and exit ramps, 16,000 linear feet of bulkhead for the widening of SR-84 along the NNR Canal and thirteen sound barrier walls.
One of the challenges in the project was the improving the capacity without affecting the existing traffic (more than 180,000 vehicles/day) and modifying the number of lanes and the speed of the corridor.
Eight interim milestones were accomplished by FlatironDragados ahead of schedule and one of them, the final configuration of the SR84 WB opened to traffic by the end of 2011, was actually finished more than one year in advance.
