Built in 1906, this Warren pony truss bridge originally spanned the Leon River on a road now County Road 222 about 7 miles northeast of Hamilton. Hundreds of steel rivets and bolts connect the 90-foot-long bridge. Triangle components often form truss bridges like this one because triangles are one of the strongest shapes in engineering design. When viewed from the side, the bridge members conform to a distinctive W shape. The Warren name comes from its English inventor, James Warren. Warren pony trusses are important for their role on county roads in Texas. The bridge was relocated through a partnership involving the Texas Department of Transportation, the Hamilton County Historical Commission, the Historic Bridge Foundation, and the Texas Historical Commission, and the Hamilton County Historical Museum accepted the bridge and prepared the site for its relocation in 2017.
