The old St. Patrick’s Bridge has connected Calgary’s East Village to the west end of St. Patrick’s Island in the Bow River since 1965, but did not continue across the river to the other side. To rectify this shortcoming, the bridge has been replaced with a new St. Patrick’s Bridge, constructed between 2012 and 2014. The design of the bridge, reminiscent of the trajectory of a stone skipping across the river, and its elegant inclined arches, make it a most attractive structure.
The new structure is supported by mageba linear rocker bearings and elastomeric bearings with movement restraints. The rocker bearings are designed to resist longitudinal and transverse loads and to facilitate significant rotations about every axis, and are made of 100 % stainless steel to ensure maximum durability and resistance to corrosion. The elastomeric bearings are designed to allow movements in all directions (free deforming) at some locations, and to allow only longitudinal movements (guided deforming) at others.
