Miami, Florida, U.S.A.
PROJECT OVERVIEW
The I-395/SR 836/I-95 Project is a partnership between the Florida Department of Transportation (FDOT) and the Miami-Dade Expressway Authority (MDX), with construction limits on State Road (SR) 836 beginning at NW 17 Avenue and continuing through the SR 836/I-395/I-95 (Midtown) Interchange to the MacArthur Causeway Bridge. The limits on I-95 are from NW 8 Street to NW 29 Street.
TIMELINE Fall 2024, subject to change due to weather or other unforeseen circumstances.
COST $818 million.
PROJECT COMPONENTS The I-395/SR 836/I-95 Project will include enhancements to three major Miami corridors:
SR 836 – This project is a continuation of MDX’s work program to modernize the SR 836 corridor. The enhancements on SR 836 are from NW 17 Avenue to the Midtown Interchange. These enhancements include double-decking SR 836, beginning just east of the toll gantry at NW 17 Avenue, rising over the center of SR 836, and touching down at I-395, east of the I-95 interchange. The double-decked section will provide drivers with a direct connection to the MacArthur Causeway that is free of local entry and exit traffic.
The existing SR 836 roadway and bridges will serve as a collector distributor system that allows drivers to enter and exit from the existing local roads and I-95. This collector distributor system will reduce the existing weaving movements resulting in enhanced safety and better traffic operations on SR 836.
In addition, the existing eastbound SR 836 ramp to northbound I-95 will be widened to include an additional lane reducing the congestion that drivers currently experience.
I-95 – These enhancements are from NW 8 Street to NW 29 Street and include the total replacement of the concrete pavement for both the northbound and southbound travel lanes.
An auxiliary lane will be added along northbound I-95 from north of NW 17 Street to NW 29 Street to receive the additional traffic from the eastbound SR 836 ramp to northbound I-95 and enhance the flow of traffic through the Midtown Interchange.
The project also includes the construction of a new connector ramp from southbound I-95 to westbound SR 836. This new connector ramp will enhance the flow of traffic and reduce weaving movements. This portion of the project will also enhance safety.
I-395 – Enhancements along I-395 are from the SR 836/I-95/I-395 (Midtown) Interchange to the MacArthur Causeway, approximately 1.4 miles long. The project will completely reconstruct the existing facility and create a signature bridge that will span 1,025 feet over NE 2 Avenue and SR5/ Biscayne Boulevard, redefining the Miami skyline with its six sweeping arches.
The project will create additional capacity on 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 offramps 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 of North Miami Avenue. NW 2 Avenue will also be reconnected under I-395, providing residents greater access.
