Inaugurated in July 2012, this contract represents the first stage of the extension project for the Miami Subway (Florida) through the new Orange Line. It is the first construction project in the railway sector achieved by a Spanish company in the United States, awarded by Miami-Dade Transit.

The section is 3.8 kilometers (km) long and includes the following main activities:

• Construction of a raised two-lane line connecting the Earlington Heights station (Metrorail) to the Miami Intermodal Center (MIC), Miami Airport, part of which has been constructed with prefabricated keystones
• Cutting-edge three-level passenger station, MIC, Metrorail
• The necessary systems to coordinate and integrate the new section with the current Metrorail system, to include operating and road systems, three electrical traction sub-stations, new roads and reconstruction of existing systems

This is the largest Metrorail extension since the system opened in 1984, and is the first branch to be constructed along the main line.
