General Bridge Description
Bridge B01 of 49023 is a five-span, steel, continuous deck truss bridge carrying U.S. Route 2 over the CutRiver in the Hendricks township in Mackinac County. The three deck truss spans measure 125'-0", 300'-0", and 125'-0" from west to east. Behind each 1-foot-wide abutment backwall is a 43'-0" reinforcedconcrete tee beam span, making the overall length of the bridge 641'-0". The out-to-out width of the deckis 37'-10", providing for two 12'-0" travel lanes with a 3'-0" shoulder and a 3'-0" sidewalk along each edgeof the roadway. The bridge is supported by reinforced concrete abutments and solid shaft reinforcedconcrete piers. Abutments and piers are clad in stone masonry.
The floor system is comprised of longitudinal stringers and transverse floorbeams, which frame into the twodeck trusses along either edge of the bridge. Span 2 contains a 50'-0" suspended span that is supportedby seated assemblies at the end of the trusses cantilevered from Spans 1 and 3. Tie-down assembliesconsisting of steel pin and link members anchor the trusses at the abutments.
The bridge substructure was built in 1941 and the superstructure was built in 1946. The superstructure waspainted in 1979. The bridge was rehabilitated in 1992, when the hold-down members for the anchor spanswere replaced. The bridge is a twin of Bridge B03 of 51021 (M 55 over the Pine River).
