T.Y. Lin International (TYLI) served as the Engineer of Record and lead designer for the Cinta Costera Viaduct in Panama City, Panama. Consisting of two structures - a roadway bridge and pedestrian bridge, the distinctive, 1.55-mile-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 Panama 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).
- TYLI’s design 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 148-foot-long post-tensioned girders and carries a total of six lanes of traffic (three lanes in each direction).
- The pedestrian bridge, which also consists of a concrete deck, is an independent bridge structure supported by two 148-foot-long post-tensioned girders.
- The pedestrian bridge is detached from the roadway bridge and has a lane for pedestrians, a lane for bicycles, and a lane for landscaping.
