• 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, including operating and road systems, three electrical traction substations, new roads, and the reconstruction of existing systems
