SECOND BRIDGE OVER THE PANAMA CHANNEL TENDER

These solutions were presented in response to an international call for tenders to build a second bridge over the Panama Canal in the vicinity of the Miranda Locks and serving to make a motorway connection between the Noth Corridor and Arrajan.

Two types of cantilever bridge were presented in  “V-leg” and “Double-V leg” type arrangements, consisting of a composite deck on truss and double box girder. The main frame is formed in steel and the approach viaducts in prestressed concrete. The construction of the main span would be made by successive cantilevering, with provisional trusses and the approach sections  erected by gradual launching.

The third proposal consisted of a double tower cable-stayed bridge with composite deck and prestressed concrete approach spans which would be erected by successive cantilevering.
