Five people died and about 14 others seriously injured.
An investigation showed that the bridge might have been damaged by debris from an earlier flood. However, the main cause of the collapse was declared to be metal fatigue.
A new concrete bridge was completed in 1917.
Which brings us to- how much better condition are our bridges in today? While they're nowhere near collapsing, of the 163 bridges listed in Spokane County's inventory, 15 are considered functionally obsolete (bridge can't support weight or traffic volumes of today's vehicles) and 11 rated structurally deficient (components such as the deck, superstructure or substructure are rated in poor condition). The Washington State Department of Transportation has 148 bridges in Spokane County with 35 rated functionally obsolete and nine structurally deficient. Of the City of Spokane's 44 bridges, three are functionally obsolete and one is structurally deficient.
Sounds scary right? It's not as bad as it sounds but also, why don't we just get them fixed? The same answer as to every other transportation question- there's just not enough money to go around. Bridges are very expensive to fix. In the coming years though, as our infrastructure continues to age, I think we will see a lot more bridges under construction as the alternative is to have them fall down.
