| Description | The I-395/SR 83611/I-95 project consists of three reconstruction projects at the interchange of I-395, SR 836, and I-95 (Midtown Interchange) in downtown Miami. The project will reduce congestion by adding capacity, improve safety by alleviating existing operational and geometric deficiencies and eliminating left-hand entrance/exit ramps, improve local access to and from I-395, and reduce evacuation time from Miami Beach. Along I-395 from the Midtown Interchange to the MacArthur Causeway (1.4 miles), the project will completely reconstruct the existing structure and create a signature bridge that will span 1,025 feet over NE 2 Avenue and SR 5/Biscayne Boulevard. The project will add additional capacity to I-395 with a total of three through lanes in each direction and provide separate connector ramps for traffic to and from I-95. The existing I-395 eastbound off-ramps at NE 2 Avenue will be moved west to North Miami Avenue, and the westbound on-ramps at NE 1 Avenue will be shifted to the west to North Miami Avenue. NW 2 Avenue will also be reconnected under I-395 providing residents greater access. The area under I-395 and the new bridge will be transformed into 55 acres of open communal space in the Overtown neighborhood known as the Heritage Trail. Improvements to SR 836 extend 1.4 miles west from the Midtown Interchange to NW 17 Avenue and include the construction of a four-lane viaduct that begins just east of the toll gantry at NW 17 Avenue, rising eastward over the center of SR 836 and allowing drivers to bypass the Midtown Interchange, touching down at I-395 east of I-95. The existing SR 836 roadway and bridges will serve as a collector distributor system to allow drivers to enter and exit from existing local roads and I-95, reducing weaving movements and improving safety and traffic operations. The existing eastbound SR 836 ramp to northbound I-95 will be widened to include an additional lane. The project will also construct a new elevated ramp from southbound I-95 to westbound SR 836 with an additional exit at NW North River Drive. Along I-95, improvements include the total replacement of both the northbound and southbound travel lanes between NW 8 Street and NW 29 Street (1.6 miles) and the addition of a seventh lane in the northbound direction to receive the additional lane from eastbound SR 836 ramp to northbound I-95 and enhance the flow of traffic through the Midtown Interchange. FDOT has partnered with MDX to combine these projects into a single design-build-finance project. |
