SR A1A - MacArthur Causeway - Miami, Florida
MacArthur Causeway (Florida A1A) extends east from Interstate 395 to span the Intracoastal Waterway (Biscayne Bay) between Museum Park and Watson Island. Photo taken 07/26/17.

The shortest spur freeway in 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 east to SR A1A (MacArthur Causeway) across Biscayne Bay. The freeway doubles as SR 836.

I-395 also comprises part of a truck route to the Port of Miami with its connection to the SR 887 (Port Miami 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.

I-395/SR 836/I-95 Project

I-395/SR 836/I-95 Project Map

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 North Miami Avenue and the westbound on-ramps at NE 1st Avenue west to North 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 (Florida 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

Miami, FL - 1970
Interstate 395 under construction in 1970. U.S. 41 formerly extended east from Downtown Miami onto MacArthur Causeway from U.S. 1 (Biscayne Boulevard) to Miami Beach.
Two roadways carry traffic along Interstate 395 east near the ramps to U.S. 1. Traffic transitioning directly from Florida 836 utilizes the inner roadway to U.S. 1 (Exit 2A) while motorists from nearby Interstate 95 use the outer roadway to Exit 2B. The two ramps lower to street level at NE 2nd Avenue, one block west of U.S. 1 (Biscayne Boulevard). Photo taken 07/05/11.
Updated signage at the same location adds the Port of Miami as a destination. Florida 887 branches south east from the Intracoastal Waterway bridge along MacArthur Causeway to the port while Florida A1A continues east toward Miami Beach. Photo taken 04/04/15.
