Business Loop I-84 - Caldwell and Nampa

Business Loop I-84 connects the cities of Caldwell and Nampa along a 13.50 mile route following old U.S. 30. The route arcs southwest along Centennial Way from Exit 27 to the couplet of Cleveland Boulevard south and Blaine Street north through Downtown Caldwell. Traffic recombines along Cleveland Boulevard as the commercial arterial leads southeast from Linden Street to Homedale Road and the Nampa city limits.

Advancing eastward, big box retail anchored by Karcher Mall lines Business Loop I-84 (Caldwell Boulevard) to Midland Boulevard in north Nampa. A second carriageway split then takes place east of Canyon Street, with 2nd and 3rd Streets carrying six lanes of traffic to Downtown. 11th Avenue angles the business loop northeast, but motorists along eastbound must navigate one block further along 3rd Street to 12th Avenue north and 2nd Street west to continue due to 11th Avenue flowing south from 2nd Street.

Garrity Boulevard takes Business Loop I-84 east from the Nampa street grid to an industrial area northwest of Nampa Municipal Airport (MAN). The route concludes by Nampa Gateway Center at Exit 38.
