Overview

SR A1A - MacArthur Causeway - Miami, Florida

MacArthur Causeway (SR 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 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.

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.
I-395 east at US 1/SR A1A - 2015

The east end of I-395 connects with SR 887 and the PortMiami Tunnel. SR 887 branches south east from MacArthur Causeway at the Intracoastal Waterway bridge to the Port of Miami while SR A1A turns southward onto Watson Island over Biscayne Bay. Photo taken 04/04/15.

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

History

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
