Klamath Falls. It bypasses the city to the west on an expressway and has a business route to serve downtown Klamath Falls. The highway continues north, first along the east shore of Upper Klamath Lake and later to the east of Crater Lake, through the dry forests of the eastern Cascade Mountains. US 97 is directly connected to Crater Lake National Park via Oregon Route 62 and Oregon Route 138. The highway travels northeast, following the Deschutes River through La Pine and to the Newberry National Volcanic Monument, where it passes over the Lava River Cave and travels around Lava Butte. US 97 expands into an expressway near the butte and turns north as it approaches Bend, the largest city in Central Oregon. The highway travels through Bend on the Bend Parkway, a four-lane expressway bypass that is supplemented by a parallel business route to the east. The business route is also used by US 20, which US 97 intersects twice north of downtown Bend. US 97 continues northeast from Bend as a divided highway through Redmond, where it reverts to a two-lane highway. It travels north across the Crooked River National Grassland to Madras, where the highway is concurrent with US 26 and splits into a pair of one-way streets. US 97 continues northeast from Madras through a series of canyons to a junction with US 197, its sole auxiliary route. The two highways travel parallel to each other on opposite sides of the Deschutes River canyon, with US 197 to the west serving The Dalles and US 97 to the east passing through the sparsely-populated area between Shaniko and Wasco. From Wasco, the highway turns northwest to descend to the Columbia River Gorge, intersecting I-84 and US 30 at Biggs Junction. Immediately after the interchange, US 97 crosses the Sam Hill Memorial Bridge into Washington. Under Oregon's named highway system, US 97 is designated as part of The Dalles–California Highway No. 4 between California and US 197 and Sherman Highway No. 42 from US 197 to the Columbia River. It is described as Oregon's most important highway east of the Cascades and serves as an alternate trucking route to the I-5 corridor. The southernmost section between the California state line and Klamath Falls is part of the Volcanic Legacy Scenic Byway, which continues to Crater Lake; the northernmost section between Shaniko and Biggs Junction is part of the
