This file consists of draft engineering drawings for the Kelly Camp Bridge replacement project located in Flathead County, Montana, specifically addressing Bridge No. 1 and Bridge No. 2 (which is similar in design).

The drawings depict detailed bridge elevation profiles, replacement bridge deck plans, and road centerline profiles showing the structural components and modifications required for the bridge replacement. Key design elements include timber decking with steel wide flanges, estomeric bearing pads, steel bearing plates bolted or welded to wide flanges, concrete abutments with epoxied anchor bolts, milled log curbing details, and treated timber curb construction. The finished deck elevation is specified at 3236.46 for the new bridge structure. The design incorporates Coastal Douglas fir glulam panels treated with copper naphthenate, with specific bolt spacing per manufacturer recommendations and all timber member holes to be drilled prior to pressure treatment. The drawings indicate modifications to existing road profiles and fill zones on existing roads, with provisions for new bridge construction adjacent to existing timber bridge infrastructure. Additional detail sheets specify carriage bolt types, C-clips, W12 x B7 specifications, and preformed joint filler requirements. The documents appear to be preliminary draft versions prepared for engineering review and coordination related to the bridge replacement scope of work.
