Proceeding south from Delta one mile on Iowa 21, at the crossing of the North Branch of the Skunk River, one comes to the Delta covered bridge (1867). This single-span 76-foot-long bridge was initially built without cover. A housing with a gable roof was added the following year. The bridge was constructed by Joseph Merryfield and James Harlan using a Burr arch truss system, a form often used on nineteenth-century Pennsylvania bridges. In 1955 the bridge was restored, and it is now used only for foot traffic.
