On the way back from Ticino to Grison we passed the San Bernardino tunnel. It was opened in 1967 and is 6.5 km long (21,000 feet). There are long stretches that are completely straight.
I processed a balanced HDR photo from a RAW exposure, carefully adjusted the curves, and desaturated the result. I welcome and appreciate your critical feedback.

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947. Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule. Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened. As the United States developed the Southwest, the Colorado River was seen as a potential source of irrigation water. An initial attempt at diverting the river for irrigation purposes occurred in the late 1890s, when land speculator William Beatty built the Alamo Canal just north of the Mexican border; the canal dipped into Mexico before running to a desolate area Beatty named the Imperial Valley. Though water from the Imperial Canal allowed for the widespread settlement of the valley, the canal proved expensive to maintain. After a catastrophic breach that caused the Colorado River to fill the Salton Sea, the Southern Pacific Railroad spent $3 million in 1906–07 to stabilize the waterway, an amount it hoped in vain would be reimbursed by the Federal Government. Even after the waterway was stabilized, it proved unsatisfactory because of constant disputes with landowners on the Mexican side of the border. As the technology of electric power transmission improved, the Lower Colorado was considered for its hydroelectric-power potential. In 1902, the Edison Electric Company of Los Angeles surveyed the river in the hope of building a 40-foot (12 m) rock dam which could generate 10,000 horsepower (7,500 kW). However, at the time, the limit of transmission of electric power was 80 miles (130 km), and there were few customers (mostly mines) within that limit. Edison allowed land options it held on the river to lapse—including an option for what became the site of Hoover Dam. In the following years, the Bureau of Reclamation (BOR), known as the Reclamation Service at the time, also considered the Lower Colorado as the site for a dam. Service chief Arthur Powell Davis proposed using dynamite to collapse the walls of Boulder Canyon, 20 miles (32 km) north of the eventual dam site, into the river. The river would carry off the smaller pieces of debris, and a dam would be built incorporating the remaining rubble. In 1922, after considering it for several years, the Reclamation Service finally rejected the proposal, citing doubts about the unproven technique and questions as to whether it would in fact save money.
where the river turia once flowed through the heart of valencia, now strides a figure across the reclaimed canvas of the former riverbed, transformed into a verdant artery of public parks. the bridge above, a remnant of past crossings, now casts geometric shadows on this grand urban garden. it's a place where the city's history is etched in every contour and corner, a seamless blend of Valencia's past and present. graffiti tags echo the voices of a vibrant community, while the verdant stretch whispers the tales of water that once carved its path here. as the city breathes and buzzes, its inhabitants move rhythmically in the riverbed-turned-park, a confluence of nature's resilience and human ingenuity.

The only time I've ever seen these bridges in the open position. Barton Swing Aqueduct (left) - the only swing aqueduct in the world and Barton Road Swing Bridge (right) - there's quite a few of these but not as a pair. And the control tower sat nicely between the two.

Glen Canyon Dam, Page AZ
Even at 21mm on a FF sensor, I could not take in the enormity of this civil engineering marvel. Located on the famous Colorado River, the same river that trickles its way through the Grand Canyon, the dam forms Lake Powell (in the background).

A Polygon derives from the greek word meaning many sides and is considered to be an unbounded sequence, or circuit of alternating segments (sides) and angles (corners).
The modern mathematical understanding of a Polygon is to describe this structural sequence in terms of an 'abstract' polygon which is a partially-ordered set (a poset) of elements.
The interior body of the Polygon is an entirely other element; and for complicated technical reasons so is the null polytope or nullitope - but that is for another future series.

Gemaal De Cruquius uit 1849 is een van de drie gemalen waarmee de Haarlemmermeer tussen 1849 en 1852 is ingepolderd. Bovendien is het de grootste stoommachine ter wereld. Het gemaal is daarna nooit gemoderniseerd en is in 1933 buiten werking gesteld. Het is genoemd naar de Nederlandse waterbouwkundige Nicolaus Samuelis Cruquius, geboren als Nicolaas Kruik in 1678 te Vlieland. De imposante combinatie van techniek en architectuur
maken dat De Cruquius een industrieel archeologisch monument van wereldformaat is. Het gemaal heeft op zijn beurt de naam Cruquius gegeven aan het dorp in de nabijheid.
Dit is het gemaal de Cruquius in het dorp Cruquius in de Haarlemmermeerpolder.
Het dorp ontleent zijn naam aan de naam van het gemaal, dat op zijn beurt weer vernoemd is naar Nicolaus Samuelis Cruquius. Met dit gemaal heeft men --samen met nog twee gemalen, de Leeghwater en de Lijnden-- van 1849 tot 1852 het Haarlemmermeer leeggepompt teneinde de Haarlemmermeerpolder aan te leggen. In 1934 is Stichting de Cruquius opgericht die het stoomgemaal nadat het overbodig werd van de sloop heeft gered. Dezer dagen valt 'de Cruquius' onder het industrieel erfgoed en is in het gebouw Museum de Cruquius gevestigd.
Hoewel de originele stoominstallaties van eertijds niet meer operationeel zijn, wordt het mechanisme dagelijks meerdere malen met behulp van elektromotoren in beweging gebracht om de werking voor de bezoekers aanschouwelijk te maken.
Zoals te zien is het geheel opgetrokken in een neogotische stijl. Deze stilering beperkt zich echter niet tot het bouwwerk op zich. Ook de machinerie is waar mogelijk in dezelfde stijl ontworpen en gebouwd.
The steam mill Cruquius is itself a Netherlands 'Rijksmonument' for the steam history of the engine within, and it has also been declared an Anchor Point of ERIH, The European Route of Industrial Heritage. It is thought to be the largest steam engine – and certainly the largest beam engine – ever built. The engine was built by Harvey & Co, of Hayle, Cornwall. The diameter of the piston is 144 inches (3.7 m).
Outside, the ringvaart canal's system of sluices, mills, and bridges, are all part of the Stelling van Amsterdam, the main dike of which runs just north of Cruquius, through Vijfhuizen. Fort Vijfhuizen is used for art exhibitions and is a short walk north of the museum along the ringvaart. What is less known is that there is also a fort Cruquius, just south of the museum, that also has World Heritage status because of its link to the Stelling van Amsterdam.
The Cruquius Pumping Station was named a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1991.

Roadford Lake, also known as Roadford Reservoir is a man-made reservoir fed by the River Wolf. The dam which carries a public road was completed at the end of 1989. It is viewed from the dam a few months later as the lake continued to fill.
It is located to the north-east of Broadwoodwidger in West Devon, eight miles (13 km) east of Launceston and is the largest area of fresh water in the southwest of England.
Operated by South West Water, it directly supplies water for North Devon. It also supplies Plymouth and southwest Devon via releases into the River Tamar for abstraction at Gunnislake.

On account of some flash floods out here in the Mojave Desert, I'm posting a photo from the archives.
Decades ago, I began a project to travel the entire length of US1 from Key West, Florida to Fort Kent, Maine. I estimate having driven over 80% of it during two trips. When you get into New England, you encounter a lot of small coastal towns. Mystic, Connecticut was a place along the way. I liked this bridge because the deck of the bridge weighs 660 tons. Somehow one of the guys from Otis elevator made the thing open and close with two 40 horsepower DC motors. Gears are part of the trick. It takes about 5 minutes to move from fully horizontal to fully open. The two concrete counterweights weigh 230 tons each. It's a clever design for 1922 engineering.
An approaching boat calls the Connecticut Department of Transportation bridge operator via VHF marine radio. Railroad crossing type gates close on each bridge approach. The bridge operator sounds a railroad locomotive class air horn when the bridge is imminently going to open. (I just about jumped out of my shoes when the horn went off.) The bridge operator was female and was friendly and courteous with tourists.
Many people recall the name of the town from an early Julia Roberts movie, Mystic Pizza. The location used for the pizza parlor in the film is not named Mystic Pizza and is actually a couple of miles north of Mystic. Meanwhile in Mystic proper, an entrepreneur has opened a business named Mystic Pizza which is popular with tourists. I'm not sure if they've survived the pandemic.
No mystical pizza for me. For dinner, I ate at a nautical-themed bar. After a long day on the road, it was a great way to wrap up the day.
Cut my pizza in six slices; I can't eat eight.

The assembly would have been crane handled into position onto the 5no Adjustable Support Brackets visible underneath the panels. The All Steel panels arrive onto site flat and are then 'formed' on curved shaping tables.The 5 Vertical Cantilever Soldiers that extend down below the Panels, and touch the existing concrete with adjustable feet, provide a 'plumbing' capability. The Cantilever Access Brackets at the top of the panels provide a Working Platform for the concreting gang.
