T.Y. Lin International (TYLI) is serving as the Owner’s Engineer to the Republic of Panama Ministry of Public Works (MOP) for the new 4th Bridge over the Panama Canal. The firm is providing specialized technical assistance during the RFP, design, construction, and commissioning phases, ensuring the implementation of the objectives of the MOP.
Featuring two dramatic towers with multiple cable planes, the signature crossing will consist of 1,010 meters of cable-stayed main bridge, a 510-meter-long by 51-meter-wide main span across the canal, and 1,500 meters of approaches. The center span will provide a 75-meter free vertical and 350-meter-wide clearance over the navigational channel to accommodate vessels for the future Fourth Set of Locks of the Panama Canal.
Due to the project location in a high seismic region, the specified bridge design criteria account for seismic effects and near-fault effects. Specified design and durability requirements also exceed AASHTO requirements, including more stringent criteria for wind, and vessel impact designs.
The 4th Bridge over the Panama Canal will be constructed on the north side of the existing Bridge of the Americas. The structure will connect west Panama with Panama City and benefit the more than 500,000 residents living on the west side of the canal.
- The bridge will have a 100-year design life and incorporate the latest in bridge design and construction technologies.
- The multimodal crossing will carry six lanes of vehicular traffic (three lanes in each direction), two-way rail lanes to be linked with Panama’s future Metro Line 3, and a bicycle/pedestrian path.
- The West Tower will feature a high-end restaurant below the superstructure and an observation deck at the top of the tower.
- The project marks TYLI’s third major bridge project involving crossings over the Panama Canal.
