The project provided for the reconstruction of the I-95/ Okeechobee Boulevard interchange from south of Australian Boulevard to Congress Avenue and replaced the outdated and dysfunctional existing clover-leaf interchange design with a new double curved box girder flyover bridge (approximately 900 LF).
Work also included providing a new eight-laned concrete girder bridge over I-95, reconstruction of all on and off ramps, new signalized intersections on Okeechobee Boulevard both east and west of I-95 at the on/ off-ramp terminals which included triple left turn movements, the addition of auxiliary and general purpose lanes on I-95 in each direction with two-lane on/ off ramps, and milling and resurfacing of existing I-95.
Project Features:
-
Ramp bridge on a sharp 490-foot radius curve carrying traffic from westbound Okeechobee Boulevard over I-95 and Okeechobee Boulevard to southbound I-95.
-
Removal of existing loop ramps in the northeast, northwest and southwest quadrants and reconstructing the loop ramp in the southeast quadrant.
-
Substructure consisting of end bents and hammerhead single column piers on pre-stressed concrete piling.

Sound walls, decorative MSE walls, decorative precast gravity walls, jack and bores, and extensive landscaping.
-
Complex MOT schemes were required to ensure traffic was afforded access to Okeechobee Boulevard and I-95 throughout the 18-month accelerated construction schedule.
-
DMG Value Engineering concept to provide full superstructure replacement in lieu of hydrodemolition and bridge jacking.
