MDX SR 836 Interchange Improvements at 87th Avenue

Description : MDX has completed the final design phase for the SR 836/Dolphin Expressway Interchange Improvements at NW 87th Avenue and is ready for construction. The project will complete system-to-system connections between SR 836 and the Palmetto Expressway and provide 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. The scope includes the partial reconstruction of SR 836 and NW 87th Avenue Interchange including replacement of all SR 836 bridges over NW 87th Avenue and widening of NW 12th Street. . A significant improvement will be the addition of a new flyover ramp that will provide direct connection from westbound NW 12th Street to westbound SR 836. This substantially reduces the 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.

Project Status : Noise wall panels on the south of SR 836 have been installed. Drainage, final grading and painting at this location will be completed by the end of January 2017. Construction to widen NW 12th Street began in July and will continue into 2017. Several beams were installed at bridges over NW 87th Avenue and their reconstruction is ongoing. This project is anticipated to be completed in the summer of 2018
