The Hectorville Covered Bridge consists of two Town lattice trusses, 52.5 feet (16.0 m) long, with a structure width of 19.5 feet (5.9 m) and a roadway width of 16 feet (4.9 m) (one lane). The bridge's exterior is clad in vertical board siding, and it is covered by a metal gable roof.
A simple lattice truss will transform the applied loads into a thrust, as the bridge will tend to change length under load. This is resisted by pinning the lattice members to the top and bottom chords, which are more substantial than the lattice members, but which may also be fabricated from relatively small elements rather than large beams.
The bridge spans the Trout River in an east–west orientation. It is of Town lattice truss design, 91 feet (28 m) in length and 19.5 feet (5.9 m) in width, with a roadway width of 16 feet (4.9 m) (one lane). It is covered by a gabled roof, and is sheathed by vertical board siding, which extends a short way inside the portals to shelter the ...
The bridge consists of two spans, 64.1 feet and 81.10 feet, with a 3.2 feet gap between them. The combined trussed portions of the bridge are 149.1 feet long. The bridge's Town lattice is an unusual design choice, but the later addition of the queen trusses are also unusual, resulting in a unique visual appearance by the bridge's unequal spans.
It is a single-span Town lattice structure, with trusses 139 feet (42 m) in length, and a roadway width of 18 feet (5.5 m). The eastern abutment is built of stone and marble slabs, and is now topped by a concrete pad, while the western abutment is marble topped by concrete. The bridge has been reinforced with laminated beams mounted below the ...
The bridge is a single-span Town lattice truss structure, with a total length of 121 feet (37 m), and a width of 18.5 feet (5.6 m) and a roadway width of 15 feet (4.6 m), sufficient for one modern travel lane.
