T.Y. Lin International (TYLI) provided architecture and engineering design services for the Panama Metro Line One (Linea Uno) in Panama City, Panama. Designed to address increasing traffic congestion in the city, Panama Metro Line One is the first metro system ever built in Central America. The 15.7-kilometer-long Rail and Transit project includes approximately 7 kilometers of tunnel, 8.7 kilometers of viaduct, and 18 stations, five of which are constructed above ground.

Project Highlights:

  • TYLI was responsible for the elevated portion of the project design, including the viaduct and all five elevated stations.
  • Design services included seismic, structural, geotechnical analysis, civil, architectural, electrical, and mechanical engineering, as well as interface/systems integration and coordination.
  • The design of the Metro stations included air conditioning systems, video surveillance, passenger information systems, wheelchair accessibility (including lifts), fire-safety systems, and electronic ticketing systems.

TYLI’s design of the viaduct portion is a twin “U” girder concept. There are three track switches for operations mounted on piers, with spans between 20 and 30 meters depending on geometry and alignment.

The southernmost elevated station (12 de Octubre) is the first above-ground station located north of the transition from the underground portion of the line. 12 de Octubre comprises a ground floor technical support level, a second level ticketing vestibule, an elevated crosswalk, operations/support offices, and third-level passenger platforms for boarding both northbound and southbound trams. The 90-meter station is supported by two rows of primary support columns, with 30-meter spans carrying the viaducts and trams and covering provided by a 108-meter-long canopy.

The remaining four stations (Pueblo Nuevo, San Miguelito, Pan de Azucar, and Los Andes) are similar in design. They typically include a ground-floor technical support level, a second level ticketing vestibule with operations/support offices, and third-level passenger platforms for boarding both northbound and southbound trams. The-90 meter stations are supported by a single row of primary support columns, with 30-meter spans carrying the viaducts and trams and a 108-meter-long canopy.
