TYLin served as the Engineer of Record and Lead Designer for the Cinta Costera Viaduct in Panama City, Panama.
Consisting of both a roadway bridge and pedestrian bridge, the distinctive, 2.49-kilometer-long marine viaduct encircles Panama City’s historic and governmental district of the Casco Antiguo.
The Cinta Costera Viaduct is part of Cinta Costera Phase III, the third phase of a coastal beltway project designed to improve traffic flow through the city. The viaduct surrounds the World Heritage Site-Archaeological Site of Panamá Viejo and Historic District of Panamá, as defined by the United Nations (UNESCO).
TYLin’s design for the Cinta Costera Viaduct features a low-profile alignment that strategically avoids infringing upon the heritage site perimeter and minimizes visual impacts.
- The roadway bridge comprises a concrete deck roadway span supported by eight 45-meter-long post-tensioned girders and carries a total of six lanes of traffic (three lanes in each direction).
- The pedestrian bridge consists of a concrete deck and is an independent bridge structure supported by two 45-meter-long post-tensioned girders.
- The pedestrian bridge has a lane each for pedestrians, bicycles, and landscaping.
