A Highway Interchange In The Takao Mountain - Near Tokyo, Japan

(Satellite)

I figured out that there are so many ramps because they wanted to build just one set of toll gates.

I should use the label bridgeGirderSteel instead of bridgeGirderConcrete.

Street View, May 2023

I couldn't figure out how to turn off the labels in Google Map, so I switched to Google Earth.

I zoomed out to see how extensive the three tunnels are.

I noticed that the next intersection to the North on 468 looked complicated, so I checked it out.

In this case, the labels help figure it out. It looks like the roads are designed to send more traffic north than south.

1929 NS/Sou/CNO&TP/CS over Kentucky River at High Bridge, KY

(Bridge Hunter broke Mar 22, 2023; Satellite, 207 photos)

To explain the title, Cincinnati built and owns the Cincinnati Southern route, but it now leases it to the Cincinnati, New Orleans & Texas Pacific (CNO&TP), which is a wholly-owned subsidiary of Norfolk Southern.

The previous bridges, 1877+1911, are documented here.

"High Bridge opened as a part of the Cincinnati Southern Railway in 1877 and soared at a height of 275 feet and 1,125 feet long. Over a century later and the bridge continues to stand as one of the tallest and most impressive in Kentucky.
"At the time it was built, High Bridge was the tallest bridge above a navigable waterway in North America and the tallest railroad bridge in the world until the early 1900s."
Kentucky Living Magazine posted
On this day in 1877, workers completed High Bridge, connecting Jessamine and Mercer Counties over the Kentucky River Palisades. It was the tallest bridge above a navigable waterway in North America (275 feet) and the tallest railroad bridge in the world until the early 20th century. The bridge was rebuilt in 1911 and is still used today by Norfolk Southern Railway to carry trains between Lexington and Danville. It has been designated as a National Historic Civil Engineering Landmark.

In 1877, the first cantilever bridge in the United States was completed in Harrodsburg, Kentucky. This railroad bridge crosses the Kentucky River Palisades, connecting Jessamine and Mercer counties. A cantilever bridge is a bridge whose main elements are cantilevers (structures that are anchored at only one end while the other projects horizontally into space). #KyHistory
Kenny McLaughlin Also known as High Bridge, the oldest highest bridge in the US still used! I’ve sat in the middle of that bridge with two friends with our legs hanging over the side holding on for dear life while a train and many cars went over it at about 40 mph. That thing flexes and shakes while that train crosses it ! It’s so high you can’t imagine how it was built! Those were the days!
Bill Johnson That's actually the second bridge. In the early 1900s, the new bridge was built around the old bridge and the elevation was raised. Later, it was made a double track bridge.

A southbound Norfolk Southern intermodal heads across High Bridge on November 8th, 2022, as it heads north across the Kentucky River on the NS CNO&TP First District at Highbridge, Kentucky.

According to Wikipedia: The High Bridge is a railroad bridge crossing the Kentucky River Palisades, that rises approximately 275 feet from the river below and connects Jessamine and Mercer counties in Kentucky. Formally dedicated in 1879, it is the first cantilever bridge constructed in the United States. It has a three-span continuous under-deck truss used by Norfolk Southern Railway to carry trains between Lexington and Danville. It has been designated as a National Historic Civil Engineering Landmark.

In 1851, the Lexington & Danville Railroad, with Julius Adams as chief engineer, retained John A. Roebling to build a railroad suspension bridge across the Kentucky River for a line connecting Lexington and Danville, Kentucky west of the intersection of the Dix and Kentucky rivers. In 1855, the company ran out of money and the project was resumed by Cincinnati Southern Railroad in 1873 following a proposal by C. Shaler Smith for a cantilever design using stone towers designed by John A. Roebling (who designed the Brooklyn Bridge).

The bridge was erected using a cantilever design with a three-span continuous under-deck truss and was opened in 1877 on the Cincinnati Southern Railway. It was 275 feet (84 m) tall and 1,125 feet (343 m) long: the tallest bridge above a navigable waterway in North America and the tallest railroad bridge in the world until the early 20th century. Construction was completed using 3,654,280 pounds of iron at a total cost of $404,373.31. In 1879 President Rutherford B. Hayes and Gen. William Tecumseh Sherman attended the dedication.

Note the abandoned route that stayed close to the Kentucky River. It had a tunnel near the upper-right corner of this excerpt. On the left side we see L&D #7 and a ferry. I presume if residents of High Bridge now want to go south or west, they have to drive a either to US-27 or US-68.

I knew that L&D #7 was part of the Kentucky River System, but I did not realize that there was such a large fleeting areas for barge.

Stephen Williamson: I question the location of this. It sure looks like the high bridge crossing the Kentucky river. I could be mistaken. The Cumberland River bridge near Somerset, KY is a different structure. The lattice paneled piers lead me to believe this is high bridge near Wilmore, KY.
Dennis DeBruler: Stephen Williamson I agree. That looks like the NS/Cincinnati Southern High Bridge over the Kentucky River.

After years of heavy railroad use, the bridge was rebuilt by Gustav Lindenthal in 1911. Lindenthal reinforced the foundations and rebuilt the bridge around the original structure. To keep railroad traffic flowing, the track deck was raised by 30 feet during construction and a temporary trestle was constructed.[6] In 1929, an additional set of tracks was built to accommodate increased railroad traffic and the original limestone towers were removed.

Peter Kirk: Surely the Garabit viaduct in France, built by Gustave Eiffel in 1882-1884, was a taller railroad bridge (407 ft) before the early 20th century. https://en.wikipedia.org/wiki/Garabit_viaduct
I'll see if I can correct Wikipedia.

Sir Adam Beck #1 taught me that the date of the first phase is used to date the power station. Originally, the generators were 25hz instead of 60hz. [NiagaraFallsInfo_station1]

Generators: Units #1, #2 and # 4 went in service on 26 January 1922.

Generators: Unit #5 went into service in 1923.

Generators: Units #3, #6 and # 7 went into service in 1924.

Generators: Units # 8 and #9 went into service on December 5th 1925.

1966 US-101 Astoria-Megler Bridge over Columbia River at Astoria, OR

(Bridge Hunter broke on Mar 22, 2023; Historic Bridges; Satellite, 1,213 photos)

Street View, Oct 2018

HistoricBridges explains why this is a continuous truss bridge instead of a cantilever truss.

"The bridge's main span is 1,232 feet in length, the longest 'continuous truss' in the nation." This was the last gap in the coastal highway from Mexico to Candada. [TravelAstoria]

When completed, it was the longest continuous-truss bridge in the world. Building the bridge was controversial. Critics called it the "bridge to nowhere." But when it opened, the critics shut up because the volume of traffic that it carried exceeded expectations. [britannia]

Street View

The bridge is so long that you can hardly see the other end. They have these trusses on the Washington (northern) end so that smaller boats don't have to cross the river to go under the bridge.

Street View, Aug 2018

This is a good view of the concrete causeway that makes up most of the length. It also shows why I read some comments complaining about the steep grade when crossing from Washington.

"At 4.1 miles..., the pale green structure is the longest continuous truss bridge in North America. In fact, even being from Oregon I did not realize how far this massive construction stretched until doing more research." It replaced a ferry that could take up to an hour to make the crossing. It stands against winds up to 150mph and a river current of 9mph during floods.

We've crossed the Astoria-Megler bridge several times in the last week, and I marvel at the engineering and builders that allowed this to be! This photo from 1965 shows the last section being placed. It was assembled in Portland, barged down and then set during high tide. Rivets and metal had only 1/4" error base, and the men on the barge and tugs and on the bridge had to coordinate all sorts of possibilities.
Don Cramer: The Bridge was built by DeLong Corp. It was the jack up barges owned by Mr DeLong that were the key to it's construction. For a man with only a 6th. grade education, He did very well.
