Interstate 395 Florida
The shortest route within the Florida Interstate system at 1.29 miles, Interstate 395 provides an essential link between Miami at Overton and Miami Beach. Extending the Dolphin Expressway (SR 836) east from the Midtown Interchange with Interstate 95 (North-South Expressway), I-395 travels an elevated route to SR A1A (MacArthur Causeway) across Biscayne Bay. The freeway doubles as SR 836, though the concurrency is not posted.
I-395 also comprises part of a truck route to the Port of Miami with its connection to SR 887 (PortMiami Tunnel). Providing direct access to the port from MacArthur Causeway on Watson Island, the $668.5 million twin-tubed tunnel opened to motorists on August 3, 2014.1 SR A1A continues east along MacArthur Causeway to 5th Street in Miami Beach.

Major improvements for Interstate 395, previously scheduled to start in December 2017, will completely rebuild the entire viaduct and ramp system between the Midtown Interchange and the Intracoastal Waterway bridge. The westbound lanes will shift slightly north onto a new footprint, with a signature span crossing above U.S. 1 (Biscayne Boulevard). The 1,025 foot bridge over Biscayne Boulevard will feature six sweeping arches, and a significantly higher vertical clearance then its predecessor.
Additionally, the 1.4-mile long project will expand I-395 to six overall lanes. Ramp changes to be made include moving the eastbound off-ramps at NE 2nd Avenue to N Miami Avenue and the westbound on-ramps at NE 1st Avenue west to N Miami Avenue. A Record of Decision on the I-395/SR 83611/I-95 Project was published by July 2010.6
Reconstruction of Interstate 395 is estimated to cost $556 million. Work runs for five years.7
The Interstate 395 section of the Dolphin Expressway was built in two phases between 19672 and 1971. Phase one included the portion between the Midtown Interchange (I-95) and Miami Avenue, while phase two completed the connection to MacArthur Causeway (SR A1A).3 The entire freeway spur opened to traffic on the afternoon of March 26, 1971.4
A 1996 FDOT improvement plan sought to expand Interstate 395 with additional travel lanes but was met with local opposition and never came to fruition. Other improvement ideas for the freeway spur arose in the early 2000s, ranging from a below grade section of freeway to new elevated spans.5

Left Exit 1A leaves the west end of Interstate 395 for I-95 south toward Coral Gables as the freeway mainline transitions into the tolled Dolphin Expressway (SR 836). SR 836 passes to the south of Miami International Airport (MIA) en route to Sweetwater and the Homestead Extension of Florida’s Turnpike (HEFT). Photo taken 04/04/15.
Interstate 95 advances south with three through lanes as Left Exit 2D leaves for I-395 east. I-395 continues along the final leg of the Dolphin Expressway to SR A1A (MacArthur Causeway) and the Port of Miami via SR 887 (PortMiami Tunnel). The succeeding southbound off-ramp from I-95 leads to NW 8th Street while the freeway continues 3.2 miles to Downtown and U.S. 1 at Brickell. Photo taken 09/30/17.
Traffic from both directions of I-95 to I-395 east combines along a separate roadway independent of the roadway linking SR 836 (Dolphin Expressway) east with MacArthur Causeway. I-395 ends along MacArthur Causeway ahead of the PortMiami Tunnel (SR 887), which opened on August 3, 2014. Photo taken 04/04/15.
West End Throwback
With the conversion of the Dolphin Expressway to all electric tolling (AET) in 2014, sign changes were made reflecting the ramp for I-95 south as the last exit before toll. This ramp will be removed and replaced with a new flyover from the right as part of the I-395 / SR 836 reconstruction project. Photo taken 03/04/14.
