All girders can then receive a magnetic particle inspection, which looks for micro cracks or potential fractures in the bridge that cannot be seen by eye.
The southbound lanes remain closed and a weight restriction of 15-thousand kg (33-thousand lbs) is still in place.
On August 28th, a canoeist paddling down the North Saskatchewan River spotted a crack in the bridge. Further investigation revealed a two centimetre crack in a support girder under the bridge.
More than 4-million vehicles cross the span annually.
The bridge has been the only vehicular means of crossing the North Saskatchewan River in Prince Albert since opening in 1960.
