South of the small community of Attica is one of Iowa's remaining nineteenth-century covered bridges. This is the 60-foot single-span Hammond Bridge over North Cedar Creek. This 1870 bridge of the Howe truss type has a single long, gabled roof; the board-and-batten wood walls have been brought up to a point about 2 feet below where they would otherwise meet the roof. This intervening open space, which was protected from the weather by the overhang of the roof, provided much-needed ventilation and light to the interior of the bridge. To reach the bridge travel south from Attica on route G76 for 1.5 miles; where G76 turns directly to the west take the gravel road that proceeds to the southeast; North Cedar Creek and the bridge are about 1.75 miles further. If one wishes to approach the bridge from Marysville, to the south, take the gravel road at the northwest corner of town; at the first junction, .3 miles from town, take the left fork (to the west); it will then be 1.6 miles to the bridge and the creek.
