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.

Latourell Creek Bridge | 45°32′19″N 122°13′08″W / 45.53868°N 122.21888°W spans Latourell Creek below Latourell Falls | ||
Shepperd's Dell Bridge | 45°32′48″N 122°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″N 122°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] | |

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. | |

East Multnomah Falls Viaduct | 45°34′45″N 122°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 Gorge Creek Bridge | 45°35′23″N 122°04′31″W / 45.58959°N 122.07541°W | Note another newer bridge there appears historic too? File:Oneonta Creek Bridge 7108 - HCRH Oregon.jpg | |

Horsetail Falls Bridge | 45°35′25″N 122°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″N 121°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. | |

It originally provided a 26-foot roadway and 4-foot sidewalks. Maximum clearance was 20 feet."[2] Now carries eastbound Interstate 84. | |

Eagle Creek Bridge | 45°38′28″N 121°55′42″W / 45.64108°N 121.92822°W, spanning Eagle Creek, bypassed by modern bridges of Interstate 84. | Closed spandrel single-span arch bridge. | |

Perhaps cover in Wyeth State Park (currently a redlink) which maybe oughta redirect to Wyeth, Oregon article, to which Wyeth State Recreation Area redirects. In Google satellite view, looks possibly in Wyeth State Park, and near Wyeth Trailhead. | |

Warren Creek Bridge | 45°41′11″N 121°42′19″W / 45.68642°N 121.70519°W | Not mentioned in NHL document. Is the photographed bridge a 2016 replica of the original bridge, perhaps? | |
Viento Creek Bridge | |||
Mitchell Point Viaduct | Part of combo with Mitchell Point Tunnel inspired by Axenstrasse in Switzerland. Since this was removed in 1966, it was not ever NRHP-listed.[2] Is this (just) the elevated approach to the tunnel, shown in photograph labelled that way? Since this was removed in 1966, it was not ever NRHP-listed. | ||
Mitchell Point Tunnel | Part of combo with Mitchell Point Viaduct inspired by Axenstrasse in Switzerland. Had windows like Axelstrasse does. Since this was removed in 1966, it was not ever NRHP-listed.[2] | ||

A 420 feet (130 m) "three-span reinforced-concrete parabolic ribbed deck arch" bridge completed in 1918. It was dismantled in 1982 and replaced by a modern bridge.
