Description 

Sadly, once the demise of the Cloquet River Bridge has taken place, this beautiful and historic structure will be the LAST remaining conventional through truss bridge in St. Louis County (at least according to the NBI|). There are a few other through trusses, but none of them are stationary conventional trusses like this one. This bridge has a few factors in its favor, though--with an ASTOUNDING sufficiency rating of 63.4 (huge for a 91-year-old truss bridge), and on a road that sees very little traffic, hopefully this bridge will be around for a while yet. The bridge has next to no rust, no bent or damaged members, and a near-perfectly intact substructure. To paraphrase, it is a bridge worth saving! Time will tell the future of this bridge.
