Completion of I-90 through Wallace occurred on September 12, 1991 with the opening of the viaduct bypassing town. This lead to the designation of the Wallace Business Loop along the former at-grade alignment of Interstate 90 through the city. Business Loop I-90 also follows old U.S. 10, which is routed along Bank Street, 5th Street and Front Street.

The route of Business Loop Interstate 90 through Wallace was renamed Harry F. Magnuson Way during a ceremony on May 1, 2010. Magnuson was the local business leader and philanthropist that led the effort to preserve Wallace from the proposed path of Interstate 90. His work led the preservation movement to add the town to the National Historic Register that aided in the relocation of the proposed Interstate 90 from through the street grid onto a 30 foot high bypass along the north edge of town.1,2
