Business Loop I-82 - Yakima

Partially a locally maintained route, the business route for I-82 through Yakima followed 1st Street (old U.S. 97) south from the interchange complex (Exit 31 B) joining Interstate 82 with the freeway along U.S. 12 toward the Yakima city center. The route circumvented downtown as a truck route using the couplet of Lincoln Avenue (west) and Martin Luther King, Jr. Boulevard (east) to N 8th Street. 8th Street led the route south to Yakima Avenue for the return to Interstate 82 at Exit 33.

Some signs were still posted along the route in May 1999. A lone overhead remained until at least 2023.
