Atlantic Bridge

Project description

The world’s busiest waterway – the Panama Canal – is currently being widened and deepened to allow for a second lane of traffic for larger containerships: the new “Panamax ships”.

Within the expansion project of this key conduit for international maritime trade, a new bridge is planned on the Atlantic side: the Atlantic Bridge (Spanish: Puente Atlántico).

The new third crossing across the canal will span 579 yards (530 m) and will have a clearance of 82 yards (75 m) to allow the largest container ships in the world to navigate beneath, connecting the Pacific and Atlantic Oceans through this man-made 48 mile (77 km) waterway.

mageba scope

mageba will deliver 16 RESTON-SPHERICAL bearings featuring uplift claws and designed according to AASHTO. Moreover, the contract comprises four LASTO-BLOCK lateral tower bearings at the tower level.

All bearings face very large displacements up to +/-40 inches (1,1016 mm) as the bridge is seismically isolated. Therefore, all bearings use mageba’s patented ROBO-SLIDE sliding surface tested for more than 31 miles (50 km) of displacement without abrasion.

ULS uplift loads will be resisted with mageba’s uplift claw design and for two piers that feature an innovative external uplift device solution designed for up to 3,500 kN (ULS).
