Segment AB is the largest and most complex segment of the I-75 corridor, and extends 3.1 miles from NW 170th Street to south of Miramar Parkway. It will provide express lanes in the existing I-75 median along with 2.6 miles of reconstruction of the Homestead Extension of Florida’s Turnpike to accommodate a third level direct median-to-median flyover express lane connection and new systems’ interchange movements, as well as new CD roads and ramps at the Miami Gardens interchange.

The improvements include 10 new bridges, 4 bridge widenings, and one bridge deck replacement. Segment AB and the systems’ interchange are critical components of the overall improvements to the corridor in both Miami-Dade and Broward counties. WGI services, as lead designer, include roadway design, structures, survey, environmental assessments and permitting, drainage, signing and pavement marking, utility coordination, and traffic control plans.
