They have a shorter lifespan than any other form of human construction.

Not true!! Bridges have a service life of on average 40 years and most go well beyond that with proper maintenance. Urban public housing is generally uninhabitable after 10-20 years.

Few bridges are lightly travelled. With thousands of vehicles crossing them every single day, it takes its toll on them. The problem is the maintenance. Its the one aspect of public roads many governments overlook and not just in Quebec. With housing, the main problem is termites. They eat away at the framework but it takes years before the damage is obvious. With a bridge, structural weaknesses are seldom apparent unless a close inspection of it is done and there are thousands of them in just one region.
