Structure Remarks

Superstructure: Beams, H=16", Wf=5.5", Tf=3/8", Tw=1/4" (Either W16x31 or W16x26's). Girder spacing 33.5" oc. Steel stringers are still in good condition with light rust at the bearing points. Diaphragm spacing 8', diaphragms are still in good condition. Bridge is very low to water. No cabling on this one.

Deck: The 3x8 decking shows signs of ware and deterioration with the ends of several boards broken/damaged in the NW quadrant (likely damage from a snow machine). There are 4" spaces between deck boards. Vegetation encroaches on only one side. With no object markers, snowcat may tend to operate to the other side of the bridge, which might be why one deck plank is broken. Running planks have signs of scaring and ware, some are broken at the ends of the bridge. No approach spans or backer boards present, vertical step up to the bridge.
