Major Highway Closures Looming as Miami Road Construction Ramps Up

While Miami's massive highway redesign project is supposed to help eventually alleviate the city's traffic-choked roads, it's accomplishing the exact opposite for now.

Thanks to Miami's roadway expansion, residents can expect major road closures between Sunday and Monday. The Florida Department of Transportation (FDOT) announced that between 10:30 p.m. Sunday evening and 5:30 a.m. Monday morning, all eastbound I-395 lanes at I-95 will be closed, along with I-95 ramps to eastbound I-395 and the Biscayne Boulevard ramp to the MacArthur Causeway.

According to FDOT, the roads will be temporarily closed to shift traffic from I-395 eastbound to the right, just after Biscayne Boulevard, to open up a new work area for construction. The Biscayne Boulevard ramp lane eastbound to the MacArthur Causeway will be also moved to the left.

The construction is part of the mega I-395/SR 836/I-95 Design-Build Project, which includes the build-out of the Signature Bridge and a double-decker portion of SR 836. Estimated to cost $840 million, the controversial project is slated to be finished by late 2027, though many longtime residents aren't holding their breath.

The latest road closures could trigger some nasty traffic gridlock around Overtown, parts of downtown, and Miami Beach.

The department is recommending the following detours.

For drivers on eastbound SR 836 continuing to I-395:
• Access the southbound I-95 exit, then exit at the NW 8th Street ramp
• Continue south on NW 3rd Court, then make a left at NW 5th Street
• Turn left on Biscayne Boulevard to access the A1A North/Miami Beach ramp
