Iowa Highway 330 (Iowa 330) is a 47-mile-long (76 km) state highway that travels northeasterly from Altoona past Albion, to just north of Marshalltown in Marshall County. Originally the two-lane, unpaved road was numbered Iowa 88. It became part of Iowa 64 in the 1903s and it received its current route number in 1969. Iowa 330 is mostly a four-lane, divided expressway along much of its length. In conjunction with U.S. Route 65 (US 65), Iowa 14 and US 20, Iowa 330 is commonly used as a connector between Des Moines and the Waterloo–Cedar Falls area.
