Bradley 's Covered Bridge , also known as the Long Cane Covered Bridge , was a covered bridge located near Troy , South Carolina . Until its fiery destruction by vandals , the Long Cane Covered Bridge , listed in the National Register of Historic Places in 1977 , was one of three covered bridges in South Carolina . The bridge was constructed in 1892 by Y.P . Reagan to replace an earlier bridge , which had been washed away in January 1892 . The new bridge was originally called Bradley 's Bridge because it was close by John Bradley 's mill . The covered bridge was built in the Howe style , a type of construction , which introduced iron rods into the bridge trusses . That popular design served as a transition from wooden bridges to those built of iron and steel . The bridge was 30 feet high and spanned 163 feet over Long Cane Creek . It rested on two stone abutments with four supporting piers in the creek bed . The bridge consisted of thirteen boxed X-panel trusses with stabilizing iron turnbuckles . Vertical board and batten siding covered the X-panel trusses and was irregularly cut and remained unpainted . The bridge portals were covered with unpainted wooden clapboards , and the roof was covered with tin .

A lattice bridge is a form of truss bridge that uses many small , closely spaced diagonal elements forming a lattice . The lattice Truss Bridge was patented in 1820 by architect Ithiel Town . Originally a design to allow a substantial bridge to be made from planks employing lower-skilled labor , rather than heavy timbers and more expensive carpenters , this type of bridge has also been constructed using many relatively light iron or steel members . The individual elements are more easily handled by the construction workers , but the bridge also requires substantial support during construction . 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 .
