Iowa Highway 340 (Iowa 340) connected U.S. Highway 18 Business (US 18 Bus.) in McGregor to Pikes Peak State Park. It was designated in 1936 to connect Pikes Peak State Park to the primary highway system, which it did until it was turned over to Clayton County in 2003. It was turned over along with 700 miles (1,100 km) of other short highways that primarily served local traffic. It was mostly replaced by County Road X56. Aside from a short connector to the state park gate, the route was a part of the Great River Road.
