The I-90 concurrency begins at exit 110, which is a trumpet interchange. Then, I-90 / US 97 interchanges Canyon Road at exit 109 and then US 97 leaves the concurrency at exit 106. From I-90, the highway turns northwest, passing SR 10 southeast of Thorp, a railroad track owned by BNSF Railway, and SR 970 in Virden to Blewett Pass, where US 97 crosses the Cascades. At Peshastin, the roadway starts its concurrency with US 2 at a diamond interchange.
