While SkyriseCities is primarily focused on global highrise construction, we are also interested in the major infrastructure projects that keep cities moving. Forum contributor Daveography has been tracking the Walterdale Bridge Replacement in Edmonton, and a recent photo update illustrates progress in the replacement of the 102-year-old bridge that currently spans the North Saskatchewan River.

Adjacent to the existing bridge, the new DIALOG Architects-designed bridge is now taking shape. Steel to construct the bridge's large arches arrived on site in mid-October, and river traffic was closed in the vicinity of the bridge site on the morning of Monday, October 26. On Sunday, November 22nd, two 56-metre-tall steel arches, weighing approximately 950 tonnes, were carefully loaded onto a pair of barges before being moved upstream and into position. The next step will involve the arches being lifted onto the support towers for assembly.

Eventually, a new bridge deck will be suspended from the arches and with new roadway connecting the Queen Elizabeth Park Road and Walterdale Hill intersection on the south side of the river with the River Valley Road/Rossdale Road/105 Street intersection to the north.

For a better understanding of the complicated construction process, we turn to this video clip released by the City of Edmonton, which shows an animated overview of the project's various stages.

Construction of the replacement bridge is expected to continue into 2016, with the previous bridge scheduled to be removed the following year.
