The Missisquoi River runs through a broad valley with moderately steep hills to the north and south. The banks of the river are shallow and covered with mostly deciduous trees and vegetation. VT 105 connects Sheldon Springs with Enosburg Falls and runs through a rural area that is dotted with farms and rural residences. The Town of Sheldon is located 1.5 miles south of the bridge. The former Central Vermont Railway nearly parallels the highway and now serves as the Missisquoi Valley Rail Trail.1 Constructed in 1947 and rehabilitated in 1980, the bridge has integrity of design, materials, workmanship, feeling, associated, location, and setting. 1 The pin-connected, Pratt through truss bridge that carries the trail over the Missisquoi River was constructed in 1900 by the American Bridge Company.

The four-span superstructure has two center spans that are each 175’ long and two approach spans that are 125’ long. The substructure consists of three reinforced concrete piers, numbered 1 through 3. The two girders consist of seven carbon steel web plates that are 1/2” thick. The approach spans consist of web plates (G1 and G6) that are two different sizes: 86’-½” long by 47’-10-3/8” tall, and 88’-1/4” long by 52’-7/8” tall. Web plates G3 and G5 are located in the center spans and measure 100’-¼” long by 37’-1-1/8” tall and 107’-15/16” long and 53’-5/8” tall, respectively. Web plates G2 and G7, which both measure 126’-1/2” long by 26’-1/8” tall, form the haunched sections of the girder at Piers 1 and 3. Web plate G4 forms the haunched section of the girder at Pier 2 and measures 116’-1/2” long by 26’-5-7/8” tall. The parabolic haunch begins 24’ from each pier. The girders are not curved at the abutments. Stiffeners are placed at each web panel junction. Two intermediate stiffeners are also riveted to both sides of each panel. Stringers are attached at the top and bottom flanges with riveted plates; stiffeners are also riveted at the stringer connections. Intermediate floorbeams, which are supported by knee braces, are spaced every 12’ along the girders and at the abutments. Diagonal “K” bracing connects the center of each floorbeam with the girders. Cross bracing is found in each end panel. Three 12” stringers rest on the floorbeams supporting the 8” cantilevered concrete deck. Knee braces, termed as sidewalk brackets on the as-built drawings, have a cyma reversa curve and connect the deck to the exterior of the girders. The 9/16” web plate is curved and riveted to the girder at each panel junction. Originally a steel pipe railing was attached to the concrete curb. The railing is currently steel that is connected to the outside of the curb. All three piers of the bridge are solid, battered concrete structures with rounded ends and center recessed panels. Piers 1 and 3 are 38’ long at the base and 29’-6” long at the cap. These same piers are 3’ wide at the cap, 5’-1” wide at the base, and 15’-6” wide at the footing. Pier 2, the 24’-8-¾” high center pier, is 39’ long and 32” wide at the cap, 5’-3/4” wide at the base, and 16’ wide at the footing. Piers 1 and 3 have shafts that are 25’-3/8” and 24’-7-3/8”, high, respectively. Piers are anchored with untreated wood piles. The concrete sill abutments are supported
