U.S. Route 97 in Oregon is the Oregon segment of a major north–south United States Numbered Highway that traverses diverse terrain from the California state line near Klamath Falls to the Washington state line near Brewster. The route links high desert plateaus, volcanic landscapes, agricultural valleys, and Columbia River crossings, serving as a principal corridor for freight, tourism, and regional connectivity across Cascade Range, High Desert, and the Columbia River region. It intersects multiple federal and state routes and connects communities such as Bend, Madras, The Dalles, and Hermiston.
Route description
U.S. Route 97 enters Oregon from California near Klamath Falls, proceeding north through Klamath County and past Upper Klamath Lake, skirting features tied to Crater Lake volcano history and Lava Beds geology. The highway intersects OR 39 and OR 66 before reaching the Deschutes basin and entering Deschutes County toward Bend, where it meets US 20, US 97 Business, and OR 126. North of Bend, the route climbs the Ochoco and crosses the Crook County landscape, intersecting US 26 and passing through Prineville and Madras near Camp Sherman and Metolius River recreation areas.
Continuing, US 97 traverses Jefferson County and Wasco County, providing access to Warm Springs, John Day Fossil Beds influences, and the agricultural plain around The Dalles, where it joins I-84 and US 30 for a stretch adjacent to the Columbia River. The highway diverges to cross the river via the Dalles Bridge, entering Sherman County and Gilliam County landscapes characterized by wheat agriculture and wind energy projects. In Umatilla County the route serves Boardman and Hermiston, intersects I-82 connections, and proceeds north to the Washington state line near Brewster and Potholes access.
History
The corridor that became US 97 follows trails and territorial roads used by Oregon Trail emigrants, Lewis and Clark Expedition routes, and trade paths between Gold Rush settlements and Pacific Northwest. Early 20th-century auto trails connected Klamath Falls to The Dalles and Hermiston; these were codified during the 1926 creation of the United States Numbered Highway System that designated U.S. Route 97. During the Great Depression, New Deal programs such as the Civilian Conservation Corps and the WPA funded improvements to pavement, bridges, and culverts along the route, including upgrades near Bend and crossing work at The Dalles Bridge, which opened in partnership with Bonneville Power Administration interests and state agencies.
Postwar expansion of Interstate Highway System corridors, notably I-84 and I-82, altered traffic patterns, funneling long-distance freight and passenger traffic but leaving US 97 as a vital regional artery. The route has seen realignments related to Bend bypass projects, Madras interchange work tied to aviation and military access (near Camp Sherman and Pentagon-funded readiness?), and bridge replacements prompted by seismic assessments influenced by studies from USGS and ODOT. Recent decades have included preservation efforts linked to National Register of Historic Places nominations for historic bridges and nearby structures associated with Bonneville Dam era developments.
Major intersections
Major intersections and concurrency points include junctions with California SR 97 at the southern terminus, OR 39 near Klamath Falls, US 20 and OR 126 in Bend, US 26 toward Prineville, connections with OR 216 and OR 7 in central Oregon, intersections with I-84 and US 30 at The Dalles including the Dalles Bridge, crossings into Sherman County and Gilliam County where it meets OR 206 and OR 19, and northern junctions with state and federal routes near Hermiston including access to I-82 corridors and the SR 97 continuation at the Washington state line near Brewster.
Traffic and usage
Traffic on US 97 varies: high volumes around Bend and Hermiston driven by tourism to Mount Bachelor, Smith Rock, and recreational sites; moderate freight movement linked to Port of Morrow, Boardman agricultural shipments, and grain elevator exports; and lower volumes across remote sections in Wheeler County and Gilliam County. Seasonal peaks occur with summer tourism tied to Crater Lake National Park, Columbia River Gorge National Scenic Area, and winter sports at Mount Hood access routes. Data collections by Oregon Department of Transportation and studies from Federal Highway Administration categorize segments for pavement management, safety improvements, and level-of-service analyses; crash mitigation efforts reference NHTSA guidelines and state traffic safety commissions.
Future developments and improvements
Planned and proposed projects along US 97 include capacity and safety upgrades funded or studied by ODOT, federal grants from FHWA, and regional planning agencies such as the Metropolitan Planning Organizations around Bend MPO and Mid-Columbia COG. Projects under consideration involve interchange redesigns near Bend and Madras, pavement rehabilitation financed through FAST Act or similar programs, bridge seismic retrofits informed by USGS seismic hazard maps, and multimodal access improvements to serve Port of Morrow, Pendleton freight flows, and Amtrak connectivity proposals. Renewable energy developments, including wind farm access and transmission corridors tied to Bonneville Power Administration upgrades, influence road design and heavy-haul allowances. Local jurisdictions have advanced proposals for business loop enhancements, safety corridor designations, and wildlife crossing mitigations coordinated with Oregon Department of Fish and Wildlife and federal land managers such as Bureau of Land Management.
