Award of Merit
Owner: Florida Dept. of Transportation – District 4
Civil Engineer/Architect: WGI
This $233-million project created a 3.1-mile, four-lane tolled roadway within a 166-ft-wide median of Interstate 75. Crews also constructed four flyovers, five bridges and two bridge and ramp widenings at the intersection of I-75 and Florida’s Turnpike. Crews constructed two 1,200-ft-long and 1,000-ft-long curved steel super-elevated bridges side by side and only inches apart. To accommodate the construction of the bridge piers in live traffic areas, the team devised a maintenance-of-traffic plan that required only a handful of detours and traffic shifts. The steel structure was set without any closures to I-75. In addition to the express lanes, the team reconstructed the Miami Gardens Drive Interchange, replaced the Bass Creek Road bridge deck and built sound barrier walls along eight neighborhoods.
The design-build team also eliminated the need for a half-mile-long divided arterial roadway and eliminated more than 300,000 sq ft of bridge deck over I-75, reducing construction costs and long-term maintenance costs. The completed express lanes were opened ahead of schedule.
WGI provided services for the following segments of the I-75 Express Lanes project:
