This is a list of bridges and tunnels on the National Register of Historic Places in the U.S. state of Oregon. It includes a number of viaducts which are considered bridges. A list of bridges, tunnels, and viaducts of the Historic Columbia River Highway is included.
Gray shading indicates that a structure has been removed from the Register. Often the road listed in the "location" column now parallels the bridge on a new one, and the old bridge is closed to traffic.
These are contributing structures in the Historic Columbia River Highway, which was listed on the National Register of Historic Places in 1983, and was further designated a National Historic Landmark District in 2000. [2]

| Sandy River Bridge |  | 45°32′18″N122°22′36″W / 45.53845°N 122.37664°W , spans Sandy River in Troutdale | Apparently a two-span truss bridge, |
| Stark Street Bridge |  | 45°30′55″N122°21′41″W / 45.51533°N 122.36137°W , brings Start Street across Sandy River in Troutdale | Pratt Truss bridge with a 200 feet (61 m) mainspan, opened in 1915. Upstream from other Sandy River bridge. |
| Crown Point Viaduct |  | 45°32′24″N122°14′39″W / 45.53994°N 122.24423°W , at Crown Point | Viaduct consisting of a sidewalk and retaining wall around tightly looped roadway (on ground, not elevated) around Vista House at Crown Point. The curve has a 110-foot radius, within specifications for HCRH roadways. |
| Latourell Creek Bridge |  | 45°32′19″N122°13′08″W / 45.53868°N 122.21888°W spans Latourell Creek below Latourell Falls | |
| Shepperd's Dell Bridge |  | 45°32′48″N122°11′52″W / 45.54659°N 122.19780°W | A single-span 100 feet (30 m) open spandrel reinforced-concrete ribbed deck arch. Its two sidewalks have "spindle-and-cap railings." [2] |
| Bridal Veil Falls Bridge |  | 45°33′15″N122°10′49″W / 45.55420°N 122.18026°W | Built in 1914, "This bridge is a skewed 100-foot reinforced-concrete deck girder span in which the solid railings serve as continuous beams. The transverse deck support members function as deck girders. Width out-to-out is 23'-2", curb-to-curb is 21 feet. The unique design allowed the bridge to span both the falls and a nearby lumber company's log flumes." [2] |
| "Cattle pass" |  | Near Bridal Veil Falls. | This cattle creep consists of a single 8-foot reinforced-concrete deck slab span. "A local landowner required construction of this Cattle Pass so that his herd could migrate to both sides of a pasture bisected by the highway's construction." [2] |
| Wahkeena Creek Bridge (and/or Wahkeena Falls Bridge?) |  | 45°34′31″N122°07′42″W / 45.57540°N 122.12830°W crosses below Wahkeena Falls. | Built in 1914, it is a reinforced concrete simple slab span, 18 feet (5.5 m) long. [2] |
| West Multnomah Falls Viaduct |  | 45°34′38″N122°07′17″W / 45.57710°N 122.12135°W | "This 400-foot viaduct consists of twenty 20-foot reinforced-concrete slab spans. Two parallel rows of 16-foot square columns, 17'-6" apart, support the deck. Roadway width is about 18 feet. The structure was designed to ride along the hillside above the railroad mainline because of tight right-of-way clearances. A concrete retaining wall runs along its south elevation. The arched railings were constructed of plaster concrete and metal lath. They represent a member of the family of bridge railing designs found on the CRH." [2] Can be viewed from east-bound Interstate 84, over Benson Lake. |
| Multnomah Creek Bridge |  | 45°34′40″N122°07′01″W / 45.57781°N 122.11708°W | A 67 feet (20 m) five-ribbed spandrel bridge. [2] |
| East Multnomah Falls Viaduct |  | 45°34′45″N122°06′42″W / 45.57920°N 122.11153°W | Built in 1914, "This 860-foot viaduct originally consisted of forty-three 20-foot reinforced-concrete slab spans. The deck was supported by two parallel rows of 16-foot-square columns, 17'-6" apart. Roadway width is about 18 feet. To provide greater stability to the structure, the Oregon State Highway Department, in 1922, added sets of intermediate posts and transverse walls at the midpoint of each span. Like the West Multnomah Falls Viaduct, this structure rises up the hillside because of tight right-of-way clearances with the nearby railroad mainline, and has a concrete retaining wall running along its south elevation. The arched railings were constructed of plaster concrete and metal lath. They represent a member of the family of bridge railing designs found on the CRH." [2] Adjacent to, and can be seen from, Interstate 84, which built out into the Columbia River. |

| Oneonta Tunnel |  | 45°35′23″N122°04′29″W / 45.58964°N 122.07471°W | Tunnel through cliff, where modern road swings outside cliff. Open for pedestrians only. |
| Horsetail Falls Bridge |  | 45°35′25″N122°04′09″W / 45.59025°N 122.06923°W | Built in 1914, this is a "three-span 60-foot reinforced-concrete deck girder trestle [which] is 24 feet wide and has a roadway measuring 22 feet. The curb and guardrail form an integral unit, cantilevered out from the girder. The delicate arched railing panels were constructed from plaster concrete and metal lath. They are identical to those found on the Oneonta Gorge Creek Bridge (1914) and the Multnomah Falls viaducts and represent one of the family of railing designs found on the CRH." [2] |
| McCord Creek Bridge |  | 45°36′53″N121°59′50″W / 45.61477°N 121.99716°W | Not mentioned in NHL doc. [2] Has this been replaced? Seems like it is neither of two current twin spans of Interstate 84. A small bridge brings the historic trail over McCord Creek. |
| Moffett Creek Bridge |  | 45°37′25″N121°58′39″W / 45.62358°N 121.97755°W | Currently carries the southbound lanes of Interstate 84 over Moffett Creek including or near Hamilton Island Reach |
| Tanner Creek Bridge |  | 45°37′53″N121°57′17″W / 45.63134°N 121.95466°W | 60 feet (18 m) girder bridge [3] Perhaps not a contributing structure of HCRH? Mentioned but not described in NHL doc. [2] |
| Toothrock Viaduct |  | 45°38′18″N121°56′13″W / 45.63831°N 121.9369°W | Built 1915 and partially reconstructed in 1996. [2] Appears to wind around Tooth Rock, above where later-built Toothrock Tunnel comes through. |
| Toothrock Tunnel |  | 45°38′18″N121°56′09″W / 45.63823°N 121.93596°W | Built in 1937, "this two-lane 827-foot tunnel was bored through Tooth Rock as part of the Bonneville Dam construction project. It originally provided a 26-foot roadway and 4-foot sidewalks. Maximum clearance was 20 feet." [2] Now carries eastbound Interstate 84. |

Multnomah Falls is a waterfall located on Multnomah Creek in the Columbia River Gorge, east of Troutdale, between Corbett and Dodson, Oregon, United States. The waterfall is accessible from the Historic Columbia River Highway and Interstate 84. Spanning two tiers on basalt cliffs, it is the tallest waterfall in the state of Oregon at 620 ft (189 m) in height. The Multnomah Creek Bridge, built in 1914, crosses below the falls, and is listed on the National Register of Historic Places.
The Historic Columbia River Highway is an approximately 75-mile-long (121 km) scenic highway in the U.S. state of Oregon between Troutdale and The Dalles, built through the Columbia River Gorge between 1913 and 1922. As the first planned scenic roadway in the United States, it has been recognized in numerous ways, including being listed on the National Register of Historic Places, being designated as a National Historic Landmark by the U.S. Secretary of the Interior, being designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and being considered a "destination unto itself" as an All-American Road by the U.S. Secretary of Transportation. The historic roadway was bypassed by the present Columbia River Highway No. 2 from the 1930s to the 1950s, leaving behind the old two-lane road. The road is now mostly owned and maintained by the state through the Oregon Department of Transportation as the Historic Columbia River Highway No. 100 or the Oregon Parks and Recreation Department as the Historic Columbia River Highway State Trail.
Crown Point is a basalt promontory on the Columbia River Gorge and an associated state park in the U.S. state of Oregon. It is located in eastern Multnomah County, approximately 15 miles (24 km) east of Portland. Crown Point is one of the scenic lookouts along the Historic Columbia River Highway, providing a panoramic view of part of the Columbia River. It stands 733 feet (223 m) above the river and is the remains of a lava flow that filled the ancestral channel of the Columbia River 14 to 17 million years ago. The Point was designated a National Natural Landmark in 1971.
Wahkeena Falls is a 242-foot (74 m) waterfall in the Columbia River Gorge in the state of Oregon.
Oneonta Gorge is a scenic gorge located in the Columbia River Gorge area of the American state of Oregon. The U.S. Forest Service has designated it as a botanical area because of the unique aquatic and woodland plants that grow there. Exposed walls of 25-million-year-old basalt are home to a wide variety of ferns, mosses, hepatics, and lichens, many of which grow only in the Columbia River Gorge. Oneonta Gorge with its 50 species of wildflowers, flowering shrubs and trees has been described as "one of the true dramatic chasms in the state." The Oneonta Gorge Creek Bridge is listed on the National Register of Historic Places.
The Umpqua River Bridge is a swing-span bridge that spans the Umpqua River in Reedsport, Oregon. It consists of a central swing span flanked by two reinforced concrete arches on each end. The swing span was necessary to accommodate tall sailing vessels which were common on the Umpqua River. The final cost of the bridge was $510,500.
The National Register of Historic Places in the United States is a register including buildings, sites, structures, districts, and objects. The Register automatically includes all National Historic Landmarks as well as all historic areas administered by the U.S. National Park Service. Since its introduction in 1966, more than 90,000 separate listings have been added to the register.
The Bridal Veil Falls is a waterfall located on Bridal Veil Creek along the Columbia River Gorge in Multnomah County, Oregon, United States. The waterfall is accessible from the historic Columbia River Highway and Interstate 84. Spanning two tiers on basalt cliffs, it is the only waterfall which occurs below the historic Columbia Gorge Scenic Highway. The Bridal Veil Falls Bridge, built in 1914, crosses over the falls, and is listed on the National Register of Historic Places.
Horsetail Falls is a waterfall located on Horsetail Creek along the Columbia River Gorge in Multnomah County, in the U.S. state of Oregon. The falls drop over a cut over the columnar basalt cliff within the Oneonta Gorge. It is one of the waterfalls along the Columbia River Highway's waterfall corridor.
Shepperd's Dell is a small canyon in the Columbia River Gorge in Oregon, located at 45.54833°N 122.195°W which is less than one-third mile southeast of Rooster Rock State Park. The Shepperd's Dell Bridge is listed on the National Register of Historic Places.
The Thomas Viaduct spans the Patapsco River and Patapsco Valley between Relay, Maryland and Elkridge, Maryland, USA. It was commissioned by the Baltimore and Ohio Railroad (B&O); built between July 4, 1833, and July 4, 1835; and named for Philip E. Thomas, the company's first president. Some claim it to be the world's oldest multiple arched stone railroad bridge. However, the Sankey Viaduct on the Liverpool and Manchester Railway was opened in 1830, and finally completed in 1833.
The Isaac Lee Patterson Bridge, also known as the Rogue River Bridge and the Isaac Lee Patterson Memorial Bridge, is a concrete arch bridge that spans the Rogue River in Curry County, Oregon. The bridge was constructed by the Mercer Fraser Company of Eureka, California. The bridge carries U.S. Route 101 across the river, near the point where the river empties into the Pacific Ocean, and connects the towns of Gold Beach and Wedderburn. A bridge with strong Art Deco influences, the Isaac Lee Patterson Bridge is a prominent example of the designs of the Oregon bridge designer and highway engineer Conde McCullough. It was designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1982. It is part of a series of notable bridges designed by McCullough for the Oregon Coast Highway in the 1930s. It was placed on the National Register of Historic Places in 2005.
The following list presents the full set of National Register of Historic Places listings in Multnomah County, Oregon. However, please see separate articles for listings in each of Portland's six quadrants.
Wilson River Bridge, also known as Wilson River Bridge at Tillamook or Wilson River Bridge No. 01499, is a bridge near Tillamook, Oregon, United States. The 1931 bridge was designed by Conde McCullough in the Classical Revival and Art Deco styles. It covers a span of 180 feet (55 m) and brings coastal U.S. Route 101 (US 101) over the Wilson River.
