HEFT Campbell Drive Interchange Improvements

Client: Florida's Turnpike Enterprise

Location: Miami-Dade County, Florida

Service: Transportation - Expressways and Managed Lanes

Project Overview

The Homestead Extension of Florida’s Turnpike (HEFT) improvements project required the design, widening, and reconstruction of the SR 821/HEFT and Campbell Drive to accommodate future needs for capacity, operational, and safety improvements. The project included a new westbound exit ramp at Campbell Drive to the northbound HEFT interchange ramp, widening of the existing southbound SR 821/HEFT off-ramp to two-lanes, widening of the SR 821/HEFT to accommodate the ramp improvements, and signal and turn lane improvements on Campbell Drive. The project included: upgrading the bridge approaches guardrails; installation of new pier protection barriers at Campbell Drive overpass bridges; replacement of the aluminum railing on all bridges; new noise walls; and analyses of the existing mast arms to determine whether backplates can be retrofitted, and if they can handle the current design wind speed criteria.
