Completion of construction of the improvements to the most congested segment of SR 836 from NW 57th Avenue to NW 27th Avenue is expected in 2019. The improvements include an additional lane in each direction, increasing capacity, and the reconstruction of the interchanges at NW 27th Avenue, NW 37th Avenue, NW 42nd Avenue, NW 45th Avenue and NW 57th Avenue. This reconstruction reduces congestion, and backups onto local roads. An innovative traffic solution called Diverging Diamond Interchange (DDI) is now operational at NW 57th and 27th Avenues, significantly improving traffic efficiency. New right hand exit ramps provide direct access to Miami International Airport and NW 42nd Avenue. Special red striped lanes on the reinforced inner shoulders will provide exclusive access to a new bus express service from the Dolphin Station Park and Ride to downtown.
Construction is underway of the SR 836/Dolphin Expressway Interchange Improvements at NW 87th Avenue in the Doral/Fontainebleau area. The project completes system-to-system connections between SR 836 and the Palmetto Expressway and provides increased capacity to meet future traffic needs along SR 836. The main purpose of the project is to improve traffic operations and safety of the SR 836 and NW 87th Avenue Interchange by reconstructing the entrance and exit ramps and widening NW 12th Street between NW 87th and NW 82nd Avenues. A significant improvement is the addition of a new flyover entrance ramp that provides a direct connection from westbound NW 12th Street to westbound SR 836. The new entrance ramp substantially reduces congestion at the intersection of NW 87th Avenue and NW 12th Street. The project also includes the construction of sound barriers, signing and pavement markings, lighting, drainage, utility coordination, Intelligent Transportation System (ITS) infrastructure and landscaping.
In partnership with the Florida Department of Transportation (FDOT), construction has commenced on the design/build project that includes the improvements to SR 836/Dolphin Expressway from the 17th Avenue Interchange, to the SR 836/I-95/I-395 Interchange, for a distance of 1.5 miles. This segment of the larger project includes improvements to SR 836/Dolphin Expressway from NW 17th Avenue to the I-95 to improve capacity and safety, and alleviate traffic congestion along the SR 836 corridor and interchanges. The FDOT segment includes the area from I-95 to I-395 incorporating a signature bridge over Biscayne Boulevard. Construction has a duration of approximately five years.

Construction is underway on a new access ramp connection from the southern terminus of SR 874/Don Shula Expressway to SW 128th Street, including widening of SW 128th Street from two to four lanes, from SW 122nd Avenue to SW 137th Avenue. The SR 874 Expressway Ramp Connector provides alternative expressway access to the area, reducing congestion on SW 120th Street and SW 152nd Street by providing additional connectivity and mobility to the rapidly growing area of West Kendall and Southwest Miami-Dade County.
The Dolphin Station Park and Ride Transit Terminal Facility opened for service on March 2, 2010 This project is a partnership between MDX, Miami-Dade County Department of Transportation and Public Works (DTPW) and the Florida Department of Transportation (FDOT), District Six. The transit facility supports the Miami-Dade 836 Express Bus Service, and will also also provide a terminus or stop for several Miami-Dade County local bus routes serving the Dolphin Mall and trolley service from cities of Sweetwater and Doral. This facility has the potential to serve a future east-west commuter rail service on the CSX line. Miami-Dade District 12 Commissioner Jose “Pepe” Diaz was instrumental in advancing this effort.
