This project provides for the implementation of express lanes along this segment of the HEFT, as well as for the Miami-Dade Expressway Authority (MDX) to incorporate a major extension of SR 874 through the heart of the HEFT/SR 874 interchange. Major scopes of work include roadway widening and construction, drainage, MOT, bridge widenings, utility and rail (CSX) coordination, architecture and site civil works, ITS, tolls, and noise walls. Constructing these improvements together via the design-build procurement method provides significant economic and time benefits as well as minimizes construction impacts to FTE and MDX customers.
