This page contains standardized bridges plans created by ARDOT for use by road contractors working for County Judges and ARDOT from the early 1920s through the late 1940s. These plans contain standard drawings for metal truss bridges (Baltimore, Camelback, Pratt, Parker, Pennsylvania, and Warren) concrete tee beam bridges, deck truss bridges, king post truss bridges, K-Truss, steel, multi-beam, timber trestle, masonry and log culverts.
