New overpasses are under construction, new sound walls are going up and space in the highway median is being converted to new express lanes. A $481 million project to create another piece of the South Florida Express Lane Network is starting to take shape along 15 miles of Interstate 75.
The FDOT District Four 75 Express project will add two managed lanes in each direction of I-75 from Interstate 595 in Broward County south to NW 170th Avenue in Miami-Dade County. At the southern end, there will be seamless continuity with the managed lanes being developed by FDOT District Six along a three-mile section of I-75 to State Road 826 / Palmetto Expressway and south along SR 826 for 10 miles to Flagler Street in Miami.
All four segments of the D4 project are now under construction. Segment A/B from NW 170th Avenue to south of Miramar Parkway includes the reconstruction of the Miami Gardens Drive interchange and Express Lane connections with the Homestead Extension of Florida’s Turnpike. Current activities center on land clearing, drainage pond excavation and sound wall installation.
In Segment C from south of Miramar Parkway to south of Sheridan Street, construction crews have started demolition and reconstruction of the Miramar Parkway overpass. The Miramar Parkway interchange will be rebuilt as part of the work.
Current activities in Segment B from south of Sheridan Street to north of Griffin Road include setting beams for the new Sheridan Street interchange bridge and sound wall construction.
In Segment E, crews are building the new bridge that will provide a direct connection from 75 Express to the 595 Express lanes. Other ongoing work includes painting sound walls and drainage pond construction.
The District Four project is scheduled for completion in mid-2019.
