Florida Department of Transportation

The SR 826 (Palmetto Expressway)/SR 836 (Dolphin Expressway) interchange is used by more than 430,000 Miami-area motorists each day. Reconstruction of the interchange was the final and largest of 12 segments comprising a 16-mile corridor along SR 826. The purpose of the $559 million project was to enhance safety, increase capacity, and improve the efficiency of motorists using the interchange. JMT (as GBF) supported the construction engineering and inspection (CEI) efforts as a subconsultant.

Capacity improvements included the reconstruction and widening of both SR 826 and SR 836, the construction of approximately 45 new bridges, and the reconstruction/modifications of the Flagler Street/SR 826 and the Milam Dairy/NW 72nd Avenue/SR 836 interchanges.

This project provides new collector-distributor ramps, which directly connect motorists with their designated exits without having to access the expressway. Other improvements include the relocation of the canal between NW 6th Street and NW 16th Street, as well as a new drainage system to treat roadway runoff, new traffic signals, lighting, and overhead electronic devices providing up-to-date traffic advisories.
