Roseman Covered Bridge Ms. McGrath

Location: Madison County, Iowa a truss beam bridge with a covering to help protect the truss and prevent extra weight, such as snow, from exerting pressure on the deck

A Truss Bridge a pair of girders supporting a deck spanning the gap between two piers is lightweight but strong because of the open, triangular beams along the sides usually deck of a truss bridge goes straight across the river, without support in the middle all beams in a truss bridge are straight can support a large amount of weight and span great distances many different truss designs

History & Facts Completed in 1883 Benton Jones, builder 107 feet in length made of wood Renovated in 1992 with cost of $152,515 Known as “haunted” bridge – Two sheriff’s posses trapped a county jail escapee in 1892 Used in Robert James Waller's novel The Bridges of Madison County and the movie
