[edit] Route description
Iowa Highway 8 begins in Traer at an intersection with U.S. Route 63. It heads southeast from Traer and then straightens out to the east. Two miles (3.2 km) west of Dysart, Iowa 8 is intersected by Iowa 21. The two highways overlap for two miles until Iowa 21 turns south at Dysart. Iowa 8 continues to the east and ends at a T intersection with U.S. Route 218 northwest of Garrison.[1]
[edit] History
Prior to becoming a primary highway, Iowa Highway 8's route was a part of the Diagonal Trail, which connected Sioux Falls, South Dakota, to Danville, Illinois. Through Iowa, it passed through Davenport, Cedar Rapids, Iowa Falls, Spencer, and Spirit Lake.[2] The Diagonal Trail was registered with the Iowa State Highway Commission on December 4, 1918.[3] When the primary highway system was created, a portion of the Diagonal Trail was assigned Primary Road No. 58.[4] When the eastern portion of Iowa 58 was rerouted, Iowa Highway 8 was formed. Iowa 8 has been relatively unchanged since its designation, with two sharp curves east of Traer eliminated for a straighter route with one more-gradual curve.[5]
