Three Bridges over Crooked River Canyon near Terrebonne, OR

1911 Railroad: (Bridge Hunter; HAER)

This location has become a history for arched bridge designs. In the background is the 1911 railroad bridge. In the middle is the 1926 road bridge. It became a pedestrian bridge in 2000 when the bridge in the foreground opened.

1911 BNSF/(Oregon Trunk Railway+GN) + UP Bridge

I was going to pass on this bridge until I learned that it is the highest railroad bridge in the United States. It was designed by Ralph Modjeski. [Bridge Hunter]

The OTR was a subsidiary of the Spokane, Portland and Seattle Railway. Along with the Great Northern, Jim Hill owned these railroads. OTR started building up the west side of the Deshutes river while Des Chutes Railroad, part of Ed Harriman's Union Pacific empire, started building up the east side of the river. Both railroads would have to cross a major tributary, Crooked River. "There was only one place where the cliffs on both sides were close enough to build a bridge. Jim Hill had obtained the rights to the location when his Oregon Trunk Railroad acquired the Central Oregon Railroad Company on December 1, 1909. The Central Oregon had laid no track and the rights to the bridge site were its principal asset. Hill's acquisition of the location forced Harriman to negotiate a settlement whereby the Oregon Trunk, Hill's railroad, would own almost the entire line from the Columbia to Bend but Harriman's company would have the right to use the track."

Dennis DeBruler: According to Bridge Hunter, this is the highest railroad bridge in the United States.
Was there a higher bridge in 1911 that has since been torn down? Because this source says it was the second highest when built.
"The bridge is 320 feet (98 m) above the river and when it was completed in 1911, it was the second-highest railroad bridge in the United States. It is a steel two-hinge arch span with a total length of 460 feet (140 m)."
[The comments discuss if this bridge was, in fact, the highest.]

"Designed by famous bridge architect Ralph Modjeski....The bridge itself is 320 feet above the Crooked River and was completed in 1911 in about 4 months. Oddly enough, the need to get the trains going over the bridge was so intense that they started rail traffic across the bridge with only half of the required rivets installed to hold it together!...The bridge itself is a two-hinge arch span with a total length of 460 feet!"

1926 Trail/US-97 Bridge 

As mentioned, this location was so good for building a bridge that Jim Hill and Ed Harriman fought for it. So when it came time to build US-97 through the area, this location was chosen for the bridge.

Note the railroad bridge in the left background. 

I'm so glad they preserved this bridge. Not only does it have an elegant truss, the portals have pylons.

Crooked River High Bridge was completed in 1926 as part of the Dalles-California Highway (U.S. 97). It was designed by State Bridge Engineer Conde B. McCuilough. The bridge is a single-span steel deck arch that is 464' long and 27' wide. The main span is 330' long and consists of a double-hinged braced spandrel deck arch. There are 134 feet of reinforced concrete approach spans. The railing is constructed of precast concrete arches, with a cast in place cap. The structure was one of the highest bridges in the United States, at 295' from deck to streambed, when it was constructed. A high line cableway was used in the erection of the structure, rather than a traveling derrick or hoist. [HAER-data]

Mike Goff comment on Bridge Hunter-2000, cropped
I was there inspecting the two highway bridges last month, it is a pretty awesome location.

I was surprised to see an HAER record for such a modern bridge. I think the record was made to document a new bridge building technique in the USA --- using temporary cable stays until the arch is closed rather than using falsework. That technique has now become common place for building an arch bridge in place. (A more common practice now is to build a tied-steel arch on shore and then float it into place.) An contemporary example of building an arch in place using temporary cable stays is the new I-74 bridges over the Mississippi River. [HAER-data, Bridge Hunter-2000]

The contractor, Kiewit, also built the arch ribs as 15 segments using traveling formworks. That is, they used a horizontal version of what is called jump-form construction when building grain elevator silos. Jump-forms are also used to build the towers for cable-stay bridges and to build concrete skyscrapers.

The length of the boom on the concrete pumping truck struck me as awful long. Then I noticed that they used the cableway to hold an extension to get the needed length.

After reading about the big 4-lane bridge built across the Mississippi River at Cape Giardeau, MO, I've started paying attention to the ratio of bridge cost per vehicle carried. The Missouri bridge was predicted to carry 26,000 vehicles per day by 2015, but it's 2018 usage was only 10,992. Bridge Hunter-2000 indicates this bridge is another big 4-lane bridge that carries only 10,000 vehicles per day.

Update:
Terence Fenton posted six photos with the comment: "Rex T. Barber Veteran Memorial Bridge (red), The Crooked River High Bridge (green), and The Trunk Railroad Bridge (black). All located at the Peter Skene Ogden State Scenic Viewpoint outside Terrebonne, OR."
