Description


Bridge No. L-4013

Bridge No. L-4013 is a singe-span, stone-arch bridge that carries an unpaved east-west road over a branch of Riceford Creek. Located in a wooded rural area of Houston County about 8 miles west of the Caledonia, the bridge is built of coursed-ashlar, buff-colored limestone. The bridge displays a semicircular arch with a 12-foot, 6-inch span. The limestone matches farmstead foundations in the general vicinity, strongly suggesting a local origin for the stone. The quarry has not been identified. The voussoirs are well-blocked and uniform, measuring 8 inches in width and 12 inches in height. Joints are about 1-inch thick. Except for a few crude patches of repainting, the mortar has almost completely disintegrated from the intrados joints. The arch, however, retains its shape without any signs of settling. The arch springs about 4 feet above grade from sharply defined impost ledges that extend outward from the intrados about 6 inches. Constructed on a slight skew, the bridge has an overall width of approximately 18 feet. Spandrel walls are continuous with slightly flared wing walls. To protect the foundations from the scour, the stream bed under the bridge has been paved in concrete. Photographs from the 1950s and 1960s show stone parapet walls with pipe-metal railings on both sides of the roadway. These features have been removed, leaving a ragged masonry line flush with the roadway. None of the alterations affects the bridge's most significant elements, which are the design of the impost ledges and the configuration of the arch itself.
