I-395 / SR 836 / I-95 Reconstruction Design-Build

Project efforts are just beginning on this $802 million Design-Build project which involves three projects that will be constructed concurrently by the Archer Western-de Moya (AW- dMG) Joint Venture (JV) to minimize impacts to the public. Metric serves as a major design team member for structures, ITS, signals, roadway and drainage elements. The three projects include:

• I-95 Concrete Replacement Project: The limits for the improvements on I-95 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. The AW-dMG team has also added 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. This portion of the project will also enhance safety, rideability and durability of I-95 along the project limits.
• I-395 Improvements: The limits on 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 interstate and create a signature bridge that will span 1,025 feet over NE 2 Avenue and State Road (SR) 5/Biscayne Boulevard redefining the Miami skyline with its six sweeping arches. The signature bridge with its high vertical clearance will transform the area beneath I-395 into 55 acres of vibrant open communal spaces for the enjoyment of Overtown residents, nearby communities and visitors. 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 I395 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.
• SR 836 Improvements: The limits on SR 836 are from NW 17 Avenue to the Midtown Interchange. This project is a continuation of MDX’s work program to modernize the SR 836 corridor. The improvements on SR 836 include the construction of a Viaduct (elevated  bridge) that begins just east of the toll gantry at NW 17 Avenue, rising over the center of SR 836 allowing drivers to bypass the I-95 Interchange touching down at I-395 east of I-95. The Viaduct will have two lanes in each direction and will allow drivers continuing east to Watson Island, PortMiami and Miami Beach to entirely bypass the Midtown interchange and its ramps. The existing SR 836 roadway and bridges will serve as a collector distributor system to allow 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 greatly reducing the congestion that drivers currently experience.
