Business Loop I-84 - Caldwell-Nampa
Traveling 13.415 miles, the business route for Interstate 84 in Canyon County loops south through both Caldwell and Nampa between Exit 27 and Exit 38. Beginning at a diamond interchange with Centennial Way, the business route arcs southward from the Boise River to a one way couplet of Cleveland Boulevard (east) and Blaine Street (west) through Caldwell. Cleveland Boulevard is former SH 19 west from Tenth Avenue and former U.S. 30 east from 10th.
The split directions of Business Loop I-84 combine ahead of the Cleveland Boulevard intersection with Linden Boulevard, where old U.S. 30 continues southeast from Caldwell to Midway, Karcher Junction and the city of Nampa. Following Caldwell Boulevard, Business Loop I-84 enters Nampa ahead of a second one way couplet using 3rd Street (east) and 2nd Street (west). This split takes the business route to 11th Avenue in Downtown Nampa, which U.S. 30 utilized to Garrity Boulevard east. Garrity Boulevard comprises an industrial arterial, returning Business Loop I-84 east to I-84 near Tiegs Corner. Old U.S. 30 travels north from there one half mile to Franklin Road east to Meridian.
4.99 miles of Business Loop I-84 along Cleveland Boulevard, between ID 19 and Homedale Road, was relinquished from state maintenance. This includes the couplet with Blaine Street 2.04 miles to Downtown Caldwell.
