I-75 Express Lanes - Segments A&B (DB)

Segment A&B included construction of new flyovers and ramps at the intersection of I-75 and Florida’s Turnpike. It was one of four design-build projects that added express lanes in the median of I-75, with a combined length of about 15 miles and extending from NW 170th Street in Miami-Dade County to I-595 in Broward County. The effort addressed congestion, accommodated future regional growth and development, enhanced hurricane and other emergency evacuation, and improved system connectivity between key southeast Florida’s transportation facilities.

OHL North America company, Community Asphalt, Corp. (CAC), constructed a 3.1-mile, four-lane tolled roadway within the 166-foot-wide median of I-75, featuring two lanes on each side of the barrier wall. It added entrance and exit access points to the express lanes and constructed I-75 and Homestead Extension of Florida’s Turnpike (HEFT) ramps, including 15 bridges to accommodate express lanes connections and implement new movements. CAC also reconstructed the Miami Gardens Drive Interchange , replaced the Bass Creek Road bridge deck, and built sound barrier walls along eight neighborhoods.

The scope of work included milling and resurfacing of the I-75’s general purpose lanes; temporary and permanent retaining walls; culvert crossing beneath Ramps H-7 and H-8; drainage; sound barrier walls; permanent and telemetered traffic monitoring sites;two tolling gantries; Intelligent Transportation System ; signing and pavement markings; lighting and landscaping.

Travel lanes along I-75 were minimally impacted during construction, as most of the work took place in the median and outside of roadway shoulders. Lane closures were implemented during the construction of ramps and access points to the express lanes during non-peak hours.
