Bridge or tunnel mileage	Location	Notes
Sandy River Bridge	45.53845°N 122.37664°W / 45.53845; -122.37664 (Sandy River Bridge), spans Sandy River in Troutdale	Apparently a two-span truss bridge,
Stark Street Bridge	45.51533°N 122.36137°W / 45.51533; -122.36137 (Stark Street Bridge), 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	45.53994°N 122.24423°W / 45.53994; -122.24423 (Crown Point Viaduct), 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	45.53868°N 122.21888°W / 45.53868; -122.21888 (Latourell Creek Bridge) spans Latourell Creek below Latourell Falls
Shepperd's Dell Bridge	45.54659°N 122.19780°W / 45.54659; -122.19780 (Shepherd's Dell Bridge)	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	45.55420°N 122.18026°W / 45.55420; -122.18026 (Bridal Veil Falls Bridge)	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?)	45.57540°N 122.12830°W / 45.57540; -122.12830 (Wahkeena Creek Bridge) 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	45.57710°N 122.12135°W / 45.57710; -122.12135 (West Multnomah Falls Viaduct)	"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	45.57781°N 122.11708°W / 45.57781; -122.11708 (Multnomah Creek Bridge)	A 67 feet (20 m) five-ribbed spandrel bridge.^[2]
East Multnomah Falls Viaduct	45.57920°N 122.11153°W / 45.57920; -122.11153 (East Multnomah Falls Viaduct)	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	45.58959°N 122.07541°W / 45.58959; -122.07541 (Oneonta Gorge Creek Bridge)	Note another newer bridge there appears historic too? File:Oneonta Creek Bridge 7108 - HCRH Oregon.jpg
Oneonta Tunnel	45.58964°N 122.07471°W / 45.58964; -122.07471 (Oneonta Tunnel)	Tunnel through cliff, where modern road swings outside cliff. Open for pedestrians only.
Horsetail Falls Bridge	45.59025°N 122.06923°W / 45.59025; -122.06923 (Horsetail Falls Bridge)	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	45.61477°N 121.99716°W / 45.61477; -121.99716	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	45.62358°N 121.97755°W / 45.62358; -121.97755 (Moffett Creek Bridge)	Currently carries the southbound lanes of Interstate 84 over Moffett Creek including or near Hamilton Island Reach
Tanner Creek Bridge	45.63134°N 121.95466°W / 45.63134; -121.95466 (Tanner Creek Bridge)	60 feet (18 m) girder bridge^[3] Perhaps not a contributing structure of HCRH? Mentioned but not described in NHL doc.^[2]
Toothrock Viaduct	45.63831°N 121.9369°W / 45.63831; -121.9369 (Toothrock Viaduct)	Built 1915 and partially reconstructed in 1996.^[2] Appears to wind around Tooth Rock, above where later-built Toothrock Tunnel comes through.
Toothrock Tunnel	45.63823°N 121.93596°W / 45.63823; -121.93596 (Toothrock Tunnel)	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.
Eagle Creek Viaduct
Eagle Creek Bridge	45.64108°N 121.92822°W / 45.64108; -121.92822 (Eagle Creek Bridge), spanning Eagle Creek, bypassed by modern bridges of Interstate 84.	Closed spandrel single-span arch bridge.
Ruckel Creek Bridge		Remains of a bridge.
Herman Creek Bridge
Gorton Creek Bridge	45.69027°N 121.77265°W / 45.69027; -121.77265 (Gorton Creek Bridge), brings Wyeth Rd. across Gorton Creek	Not mentioned in NHL nomination. 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.
Lindsey Creek Bridge	45.68754°N 121.71457°W / 45.68754; -121.71457 (Lindsey Creek Bridge)	Not mentioned in NHL doc.^[2]
Warren Creek Bridge	45.68642°N 121.70519°W / 45.68642; -121.70519 (Warren Creek Bridge)	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?
