Iowa Highway 64 (Iowa 64) is a 64-mile-long (103 km) state highway that runs across two counties in east central Iowa. It begins at an interchange with U.S. Route 151 (US 151) in Anamosa and ends at the Savanna-Sabula Bridge over the Mississippi River near Sabula. It continues through Illinois as Illinois Route 64. The western half of the highway makes up the Grant Wood Scenic Byway.
At one time, Iowa 64 spanned the length of the state. It began at the Missouri River in Council Bluffs where it connected to N-64 in Omaha. It headed northeast and east on highways that today are roughly parallel to Interstate 80 (I-80) and US 30. In 1969, however, Iowa 64 was shortened to its current extent.
Iowa 64 begins at an interchange with US 151 in Anamosa. West of US 151, the road is County Road E28 (CR E28) or Anamosa's Third Street, while east of US 151, Iowa 64 begins its eastward trek. It leaves Anamosa heading to the south-southeast. After an S curve that takes the road to the south and then back east, the highway passes Antioch School, which Iowa painter Grant Wood attended for four years.
Iowa 38 overlaps Iowa 64 for the next 2 miles (3.2 km) before splitting off to the north. Iowa 64 continues east for another 5 miles (8.0 km) and arrives in the town of Wyoming. Upon arriving in Wyoming, Iowa 64 meets with another north–south state highway, this time Iowa Highway 136. At the eastern end of Wyoming, Iowa 64/Iowa 136 come to a T intersection where the original stretch of Iowa 64 comes to an end. Iowa 136 splits off to the south, while Iowa 64 splits off to the north very briefly before curving eastbound once again. Five miles (8.04 km) after leaving Wyoming, Iowa 64 enters Jackson County. Iowa 64 passes through the small towns of Monmouth and Baldwin and bypasses the village of Nashville before arriving in Maquoketa, the seat of Jackson County.
Iowa Highway 64 intersects U.S. Route 61 in western Maquoketa. The stretch of Iowa 64 between US 61 and Main Street in Maquoketa is a part of U.S. Route 61 Business. At the eastern city limits of Maquoketa, Iowa 64 intersects with Iowa Highway 62 which heads north-northeast from Maquoketa towards Bellevue. After Maquoketa, Iowa 64 continues east through rolling farmland before descending into the Goose Lake Channel and intersects Jackson County Route Z20, formerly Iowa Highway 113, near Spragueville. Iowa 64 leaves the Goose Lake Channel east of Preston.
About 7 miles (11 km) east of Miles, Iowa Highway 64 meets U.S. Route 67, which joins Iowa 64 from the south for its last half-mile (0.80 km). US 67 ends at the intersection with U.S. Route 52 west of Sabula. Iowa 64 and US 52 overlap each other for their last 4 miles (6.4 km) in Iowa. Before entering Sabula, US 52/IA 64 cross the Mississippi River backwater Sabula Lakes causeway. North of Sabula, the US 52/IA 64 causeway divides the Mississippi River from Sheepshead Bay, another backwater area. At this point, US 52/IA 64, directionally signed south and east, respectively, are heading north. US 52/IA 64 turn east and cross the main channel of the Mississippi River on the Savanna-Sabula Bridge, becoming U.S. Route 52/Illinois Route 64. Immediately after entering Illinois at Savanna, US 52/IL 64 intersect Illinois Route 84. Illinois Route 64 provides a direct link to Chicago.
