The Province of Quebec has invested $11.6 B for bridge and overpass rehabilitation and maintenance (2007-10).
While travelling in Quebec this past weekend I couldn’t help but notice this bridge that is apparently in dire need of rehabilitation. It reminded me of the unexpected bridge collapse (Rue de la Concorde near Montreal) that killed 5 people and injured 6. Since that time, the Quebec Ministry of Transportation ramped up inspection of all bridges in their jurisdiction and held a public inquiry.
Improper rebar detailing during the design of the de la Concorde’s abutments; improper rebar installation at the time of construction and use of a low quality concrete, which proved to be inadequate to withstand freeze-thaw cycles in the presence of road salts, all created a foundation for the bridge’s collapse on Sept. 30, 2006, the commission stated.
After the commission report was released, the Quebec government announced $11.6 billion in funding, over the next four years, for bridge and overpass maintenance. A new bridge and overpass agency responsible for maintenance of the structures was created.

The Ontario Good Roads Association (OGRA) is currently updating their Municipal Data Works (MDW) website and their bridge inspection module. According to the MDW newsletter the new module will incorporate changes made to the Ontario Structure Inspection Manual (OSIM) in 2008 by MTO. In addition, rehabilitation and repair information can be stored and structure rehabilitation requirement reports can be prepared.
CentreLine: Quote from the commission report “Bridge rehabilitation is just one of many modernisation projects Québec must undertake and one that should not be neglected because bridges are just as important to our quality of life as roads, waterworks and sewer systems, drinking water and wastewater treatment plants, public buildings, schools, hospitals, public transit systems and parks”.
