The MIC is located on Northwest 21st Street near North Douglas Road (West 37th Avenue), east of Le Jeune Road (West 42nd Avenue) and Miami International Airport (MIA), and south of the Miami River and the Airport Expressway (SR 112).

The MIA Mover began to operate at the MIC on September 9, 2011, followed by Metrorail on July 28, 2012; Tri-Rail on April 5, 2015; and Greyhound on June 24, 2015.

Amtrak and the Florida Department of Transportation (FDOT) engaged in years of lease negotiations before the railroad suddenly pulled out of talks in December 2024, saying that operating its trains to the station would be too expensive.

When Amtrak took over intercity passenger service in May 1971, it continued to use the former Seaboard Air Line Railroad (SAL) station on NW 7th Avenue in Allapattah, two miles north of downtown.

In 1989, the Miami International Airport Area Transportation Study recommended the booming Miami metropolitan area invest in an intermodal hub to connect the new rapid transit and commuter rail services to local and intercity bus routes at the airport.

The Intermodal Surface Transportation Efficiency Act of 1991, which gave additional powers to regional agencies and emphasized non-auto modes, prompted FDOT to proceed with the proposal.

The Transportation Infrastructure Finance and Innovation Act of 1998 allowed projects of regional or national significance to apply for federal funding.

[3] In 2002, Miami-Dade County approved a public referendum for a half-cent sales tax to support transportation expansion in the region.

[8] The Metrorail expansions funded by the 2002 sales tax were to primarily serve lower-density residential areas, causing them to have poor ridership-to-cost projections.

Sales tax revenue was hurt by the late-2000s recession, and much of what was collected was instead used to cover operating expenses due to mismanagement and questionable hiring practices in the transit agency.

These issues made the expansions ineligible for partial funding by the Federal Transit Administration, and they were effectively canceled in July 2010.

[3] The main part of the Roadways Program, including the MIC-MIA Interchange and the Le Jeune Road modifications, were completed on May 16, 2008.

[3] After two years of construction, the MIA Mover station received a certificate of occupancy in January 2011, allowing final systems to be installed.

Hialeah Market station was upgraded with a temporary ticket office, additional parking, restrooms, and shuttle bus service to the airport.

While the platforms can accommodate the nine-to-ten-car trains used for Amtrak's Silver Star (now temporarily replaced by the Floridian) and Silver Meteor, Amtrak runs longer trains during the winter months that can be up to twelve cars long to accommodate increased passenger demand.

[16] NW 25th Street is located immediately adjacent to the station's north end, which prevents easy extension of the platforms to accommodate longer trains.

[18] After the decision was made not to close the NW 25th Street crossing, FDOT spent $380,000 to demolish the partially constructed platform extensions.

[19] In October 2013, FDOT announced plans for a $9 million solution; the NW 25th Street crossing would remain open but would be blocked by longer winter season trains while they were stopped at the station, which could last up to 45 minutes once or twice a day.

Amtrak CEO Stephen Gardner stated, "The company is evaluating technical and operational aspects of the move.

[26] Amtrak reversed course in December 2024, sending a short letter to transportation officials negotiating the station lease's final details.

Metrorail, which provides service Downtown Miami and points south, departs from the upper level in the northern direction.

On the ground level, four tracks serve Tri-Rail and possible future Amtrak service towards Fort Lauderdale, West Palm Beach, and points north.

[citation needed] A footbridge over the Tamiami Canal is planned to connect the station with the Miami Freedom Park sports complex.
