Historic Columbia River Highway, USA

The Historic Columbia River Highway, often abbreviated as HCRH, is a roughly 75-mile scenic byway in Oregon, stretching from Troutdale (near Portland) eastward through the Columbia River Gorge National Scenic Area to The Dalles. Designated as America's first planned scenic roadway and a National Historic Landmark, it winds along the southern bank of the mighty Columbia River, showcasing dramatic basalt cliffs, lush temperate rainforests, and over a dozen waterfalls cascading from the gorge walls. Engineered with elegant viaducts, tunnels, and stone guardrails, the highway offers a blend of natural wonders and early 20th-century architecture, with no commercial development to interrupt the views. It's ideal for leisurely drives at 35-45 mph, cycling on car-free sections, and accessing hiking trails. Managed by the Oregon Department of Transportation, U.S. Forest Service, and Oregon State Parks, it's free to access, though some sites require permits for parking or hiking.

 

History

Origins and Planning
The origins of the Historic Columbia River Highway trace back to the challenges of traversing the Columbia River Gorge, a dramatic landscape carved by the Columbia River through the Cascade Mountains. In the 19th century, Oregon Trail pioneers struggled with this barrier until the Barlow Road opened in 1846 as a detour around Mount Hood. By the 1870s, a rudimentary wagon road known as The Dalles and Sandy Wagon Road was built along the south shore, but it featured treacherous 20% grades and narrow paths unsuitable for emerging automobiles.
The push for a modern highway gained momentum in the early 1900s amid the "good roads" movement and the rise of automobiles like the Model T. Key figures included lawyer and entrepreneur Sam Hill, a fervent advocate for improved infrastructure who traveled extensively in Europe and was inspired by scenic routes such as Switzerland's Axenstrasse. Hill, founder of the Maryhill Museum of Art, experimented with innovative designs on the Maryhill Loops Road in Washington State—the first asphalt road there, completed in 1911 using horseshoe curves to navigate steep terrain. Facing resistance in Washington, Hill shifted focus to Oregon, helping establish the Oregon State Highway Commission in 1913.
Engineer Samuel C. Lancaster, Hill's collaborator, was appointed to lead the project. Lancaster conducted surveys from September 1913 to January 1914, prioritizing aesthetic and scenic value over purely economic considerations. As locating engineer John Arthur Elliott noted, factors like grades, curvature, and cost were secondary to accessing "natural beauty spots" such as waterfalls, canyons, and mountain vistas. Multnomah County initially funded $75,000, with the state overseeing design to bypass local politics. Governor Oswald West demonstrated feasibility in 1912 by using prison labor to clear a path over Shellrock Mountain.
Other notable contributors included timber magnate Simon Benson, who financed Hood River County bonds in 1914 to cover cost overruns, and bridge designer Conde McCullough, who later gained fame for his work on U.S. Route 101.

Construction Timeline and Phases
Construction unfolded in phases across Multnomah, Hood River, and Wasco Counties, costing about $11 million in total (adjusted for inflation, a significant investment). The highway featured gentle 5% maximum grades, 200-foot minimum curve radii, and an 18-foot-wide macadam or asphalt pavement with gravel shoulders—standards advanced for the era.

Multnomah County (1913–1916): Work began with a 21-mile survey to the Hood River County line. Innovations included comprehensive drainage systems with concrete curbs, gutters, and culverts to protect against the gorge's heavy rainfall. Eleven reinforced concrete bridges and viaducts were built, along with masonry retaining walls. The Oneonta Tunnel, the first of five, opened in October 1914 near Horsetail Falls. Surfacing with Warrenite (a bituminous material) was completed by summer 1915, making it the first paved highway in the Pacific Northwest. A new Sandy River Bridge replaced one destroyed in 1914, and the section was dedicated in June 1916 at Multnomah Falls and Crown Point. Photographers like William Henry Jackson captured the process.
Hood River County (1914–1916): Funded by bonds, construction included the iconic Mitchell Point Tunnel, begun in March 1915 and opened in September for $47,000. This 390-foot tunnel featured five windows for light and views, mimicking European designs. Loops were added to ascend steep grades, and the Hood River Bridge was rebuilt in 1918.
Wasco County (1918–1922): The final inland route via Rowena Crest incorporated dramatic loops to descend 600 feet over 2 miles. Bridges designed by McCullough spanned canyons, and the section followed an abandoned railroad grade. The highway was fully paved and opened on June 27, 1922, with Benson symbolically laying the last asphalt. It became part of Columbia River Highway No. 2, extending to Astoria and Pendleton.

Engineering Features and Scenic Highlights
The highway's design emphasized harmony with the environment, minimizing earthmoving while maximizing views. Standout features included:

Bridges and Viaducts: Structures like the Multnomah Creek Bridge, Shepperd's Dell Bridge, and Eagle Creek Bridge showcased reinforced concrete and elegant arches.
Tunnels: Besides Oneonta and Mitchell Point, the Mosier Twin Tunnels (1920) had windows in the east tunnel.
Loops and Overlooks: The Figure-Eight Loops at Crown Point, Hood River Loops, and Rowena Loops allowed graceful navigation of steep terrain. Vista House at Crown Point, completed in 1918 as a rest area with marble interiors, offered panoramic views and served as a memorial to Oregon pioneers.
Guard Walls and Drainage: Dry masonry walls blended with the landscape, and innovative drainage prevented erosion.

Usage and Early Popularity
Upon opening sections progressively from 1914 onward, the highway quickly became a tourist draw, integrated into U.S. Route 30 in 1926. It facilitated pleasure drives through the gorge, connecting coastal and eastern Oregon while promoting economic growth through tourism.

Decline and Bypassing
By the 1930s, increasing traffic, rockfalls, and the need for faster routes led to its decline. The Bonneville Dam construction in the 1930s necessitated realignments, closing parts like the east portal of Toothrock Tunnel. The Mosier Tunnels were widened in 1938 for trucks, but the highway was largely bypassed by the water-level route of Interstate 84 (originally Columbia River Highway No. 2) from the 1930s to 1950s. Sections were abandoned, with the Oneonta Tunnel sealed in 1948.

Preservation and Current Status
Preservation efforts began in earnest with its 1983 addition to the National Register of Historic Places as the Columbia River Highway Historic District, encompassing 38 structures over 529 acres. The 1986 Columbia River Gorge National Scenic Area designation spurred reconnections. Restorations included reopening the Oneonta Tunnel in 2009 for pedestrians and cyclists after a $1.5 million project. The 2017 Eagle Creek Fire damaged sections, but they reopened in 2018.
Today, the highway is maintained by the Oregon Department of Transportation as Historic Columbia River Highway No. 100 (partially U.S. Route 30) and by the Oregon Parks and Recreation Department as the Historic Columbia River Highway State Trail. About 40 miles remain open to vehicles, with 7 miles between Hood River and Mosier dedicated to non-motorized use since 2000. It serves as a bicycle-friendly alternative to I-84, attracting visitors for its historical and scenic value.

 

The Route: Major Stops and Highlights

The highway is best driven west to east, following the river's flow, and can be completed in 3-5 hours non-stop, but plan 1-2 days for explorations. It's divided into three main segments: the western "Waterfall Corridor" (Troutdale to Ainsworth), the central restored trail sections, and the eastern drier plateau to The Dalles. Mileposts aren't consistently used, but distances from Troutdale provide reference. Below is a detailed list of key stops, organized west to east, with descriptions, significance, and activities. This focuses on highlights among dozens of pullouts and trails.

Section: Western Waterfall Corridor (Miles 0-30 from Troutdale)Key Stops: Portland Women's Forum State Scenic Viewpoint (Mile 3); Vista House at Crown Point (Mile 4); Latourell Falls (Mile 6); Shepperd's Dell Falls (Mile 8); Bridal Veil Falls (Mile 9); Wahkeena Falls (Mile 12); Multnomah Falls (Mile 13); Oneonta Gorge (Mile 15); Horsetail Falls (Mile 16)Description and Significance: Begins with sweeping gorge panoramas from the Women's Forum overlook, honoring the highway's female advocates. Vista House, a 1918 octagonal observatory atop a 733-ft promontory, serves as a memorial and info center with Art Nouveau details. Waterfalls abound: Latourell plunges 249 ft over columnar basalt; Multnomah, at 620 ft, is Oregon's tallest with a historic lodge and Benson Footbridge. Oneonta features a slot canyon hike through chest-deep water (seasonal). These sites showcase the gorge's volcanic geology and misty microclimate.Activities and Tips: Short hikes (e.g., 0.2-mile paved path to Latourell base); photography from viewpoints; picnicking at Multnomah Lodge. Tip: Start early to avoid crowds; timed-entry permits required for Multnomah area (May-Sept, $1 online); watch for rockfall and slippery trails.

Rowena Crest offers hairpin turns and wildflower meadows (peak April-May). Memaloose provides river views with indigenous history ties. The Discovery Center museum interprets gorge ecology, Lewis and Clark, and pioneer trails.Activities and Tips: Wildflower hikes at Tom McCall (2-mile loop); windsurfing in Hood River (world-renowned spot); museum visits ($10 entry). Tip: End with fruit stands in Hood River Valley; watch for strong winds affecting driving.

 

Activities

Driving: The primary experience—curvy, two-lane road with pullouts for vistas; RVs under 35 ft recommended due to tight turns.
Biking/Hiking: Over 100 miles of trails, including the Eagle Creek to Tunnel Falls (12 miles round-trip) and car-free State Trail segments; e-bikes allowed on some paths.
Camping: Options like Ainsworth State Park (tents/RVs, reservations advised) or primitive sites; nearby RV parks in Hood River.
Other: Windsurfing/kiteboarding in the gorge's winds; wildlife viewing (osprey, salmon); wine tasting in Hood River Valley; sternwheeler cruises from Cascade Locks. Detours to Mt. Hood or Washington side add variety.

 

Best Times to Visit and Tips

Spring (April-June) for waterfalls at peak flow and wildflowers; summer (July-Aug) for warm weather but crowds; fall (Sept-Oct) for foliage and salmon runs; avoid winter due to ice/snow closures. Year-round access, but check ODOT alerts for rockslides or fires (e.g., post-2017 Eagle Creek Fire recovery). Download offline maps for spotty cell service; fuel up in towns as no services on the highway. Respect nature—stay on trails to prevent erosion; leashed pets allowed but not in some buildings. For families or accessibility, focus on viewpoints like Vista House; permits needed for popular hikes ($5/day via Recreation.gov).
