This project consisted of widening and rehabilitation of 3.3 miles of an existing six-lane major urban expressway to an eight-lane section with HOV capability, including revisions to three interchanges, modifications to five bridge structures and approximately 9600 LF of permanent and temporary retaining walls. Bridge types included a complicated replacement using a simple span steel plate girder under extremely tight TCP conditions, two new off ramps using pre-stressed AASHTO girders, and two widenings involving spirals. The project also included an extensively phased TCP plan which was required due to the extensive traffic which exists.

The stormwater management system was installed entirely within the existing right-of-way utilizing French drains and exfiltration systems. The project was permitted through Dade County Department of Environmental Resources Management and SFWMD.

This design project was completed in 1993 and design fees were $1,180,000. Construction of the project is essentially completed.
