SPANNING BAD GROUND
The most cost-effective design for two exit ramps that had to cross unstable and potentially contaminated soil underlying the new Florida Turnpike/Interstate Highway 595 Interchange were cellular-spine bridges. The bridges follow curved alignments and are unique among the more than 90 elevated segments along the new interstate. The ramps consist of a 775-ft, stand-alone structure that will carry northbound traffic off the turnpike to eastbound I-595 and a 386-ft interfacing extension of a steel box girder bridge for northbound traffic off the turnpike to westbound I-595. The cellular structure has the outward appearance of a retaining wall. It satisfied the Florida Department of Transportation's design criteria for esthetics and was cost-effective at $36/sq ft.
