This nineteenth-century engineering marvel never turned a profit. It is 6.4 kilometres (4 miles) long and only 25 metres (81 feet) wide at sea level, making it impassable for many modern ships. It is currently of little economic importance and is mainly a tourist attraction.
A canal through the narrow Isthmus of Corinth that separates the Peloponnese from the Greek mainland was proposed as early as the 7th century BCE. At that time Corinth settled for a cheaper, simpler solution: a stone carriageway along which boats could be portaged. Roman emperors starting with Julius Caesar also expressed interest in a canal, and Nero began actual construction, breaking ground with his own hands in 67 CE. The workforce consisted of 60,000 Judean captives. But they had dug only about a tenth of the distance before Nero died and Rome lost interest.
The modern attempt began in 1882, after Greek independence from the Ottomans. It took 11 years to complete, bankrupting two construction companies, the owner of the second, and the bank that backed it.
Even after completion, the canal was underutilized. The limestone walls were unstable, being undermined by ships' wakes and collapsing into the canal. The narrow waterway was difficult for ships to navigate, and strong tidal currents arose as a result of differences in the timing of tides in the Ionian and Aegean seas. The high walls also funneled winds. As a result, demand for its use by ships was only a fraction of what had been predicted.
The canal suffered heavy damage in WWII. The retreating British blew the bridge rather than allow it to be taken by the Germans. Then the retreating Germans used explosives to trigger landslides to block the canal, destroyed the rebuilt bridges and dumped locomotives, bridge wreckage and other infrastructure into the canal to hinder repairs. The United States Army Corps of Engineers began to clear the canal in November 1947 and had it reopened at full draft in about a year.

The fog comes
on little cat feet.
It sits looking

Looking south towards Michigan / the United States. The International Railroad Bridge was built in 1887 by the Dominion Bridge Company Limited and is an example of a Camelback Truss Span- -a Parker Truss design variation; the bridge consists of nine spans across the St. Mary's River / St. Marys Rapids, and features pinned and riveted connections, a-frame portal bracing, v-lacing support through out, stone abutments and piers. The bridge connects Sault Ste. Marie, Ontario Canada to Sault Ste. Marie, Michigan, United States. The bridge was originally built by the Canadian Pacific Railroad Company and is now owned by the Canadian National Railway Company. Black and white processing alchemy by Nik Silver Efex.
The Falkirk Wheel is a rotating boat lift in Scotland, connecting the Forth and Clyde Canal with the Union Canal. The lift is named after the nearby town of Falkirk in central Scotland. It opened in 2002, reconnecting the two canals for the first time since the 1930s as part of the Millennium Link project.
The plan to regenerate central Scotland's canals and reconnect Glasgow with Edinburghwas led by British Waterways with support and funding from seven local authorities, the Scottish Enterprise Network, the European Regional Development Fund, and the Millennium Commission.
Planners decided early on to create a dramatic 21st-century landmark structure to reconnect the canals, instead of simply recreating the historic lock flight.
The wheel raises boats by 24 metres (79 ft), but the Union Canal is still 11 metres (36 ft) higher than the aqueduct which meets the wheel. Boats must also pass through a pair of locksbetween the top of the wheel and the Union Canal. The Falkirk Wheel is the only rotating boat lift of its kind in the world, and one of two working boat lifts in the United Kingdom, the other being the Anderton boat lift.
The two canals served by the wheel were previously connected by a series of 11 locks. With a 35-metre (115 ft) difference in height, it required 3,500 tonnes (3,400 long tons; 3,900 short tons) of water per run and took most of a day to pass through the flight.
By the 1930s these had fallen into disuse, and the locks were dismantled in 1933.
The Forth and Clyde Canal closed at the end of 1962, and by the mid-1970s the Union Canal was filled in at both ends, rendered impassable by culverts in two places and run in pipes under a housing estate.
The British Waterways Board (BWB) came into existence on 1 January 1963, the day the Forth and Clyde Canal was closed, with the objective of finding a broad strategy for the future of canals in the United Kingdom.
In 1976, the BWB decided after a meeting with local councils that the Forth and Clyde Canal, fragmented by various developments, was to have its remaining navigability preserved by building new bridges with sufficient headroom for boats and continuing to maintain the existing locks.
Restoration of sea-to-sea navigation was deemed too expensive at the time, but there were to be no further restrictions on its use.
MMA 1979 survey report documented 69 obstructions to navigation, and sought the opinions of twenty interested parties to present the Forth and Clyde Local (Subject) Plan in 1980.
The Lotteries Act 1993 resulted in the creation of the Millennium Commission to disseminate funds raised by the sale of lottery tickets for selected "good causes."
In 1996, when sufficient funds had been accumulated, the Commission invited applications to "do anything they thought desirable ... to support worthwhile causes which would mark the year 2000 and the start of the new millennium."The conditions were that the Commission would fund no more than half of the project, with the remaining balance being covered by project backers.
The BWB had made an earlier plan for the reopening of the canal link, which comprehensively covered the necessary work. In 1994, the BWB announced its plan to bid for funding, which was submitted in 1995 on behalf of the Millennium Link Partnership. The plans called for the canals to be opened to their original operating dimensions, with 3 metres (9.8 ft) of headroom above the water. The whole project had a budget of £78 million.
On Valentine's Day 1997, the Commission announced it would support the Link with £32 million of funding, 42% of the project cost.
The Wheel and its associated basin was priced at £17 million, more than a fifth of the total budget.Another £46 million had to be raised in the next two years before construction could commence, with contributions from BWB, seven local councils, Scottish Enterprise, and private donations being augmented by £8.6 million from the European Regional Development Fund.

Dades Gorge or Gorges du Dadès, Morocco. A gorge carved by the Dades River separates Atlas and Anti-Atlas (or Lesser Atlas) mountain range. Recently the gorge and neighboring Berberian kasbahs became a popular tourist attraction.
The Dades Valley, also known as a Road of a thousand Kasbahs, stretches 160 km (100 mi) from Ouarzazate to the east of Tineghir. The winding road offers stunning views to the gorge and historic kasbahs. Tourists often refer to this as the most memorable experience in Morocco.
Here’s a 45-sec video that shows the winding roads in all their splendor:

The Ferro-Concrete Review was a monthly journal produced to publicise the Mouchel-Hennebique method of reinforced concrete construction 'in engineering and architetcural practice'. Edited by W Noble Twelvetrees it is a highly informative periodical full of details and illustrations of numerous contemporary construction projects. The Mouchel-Hennebique method was the result of the engineer L G Mouchel being the British agent for the Hennebique French/Belgian method of early concrete reinforcement patented by François Hennebique (1842-1921).
The reconstruction of road bridges is often commented on in the Journal, at a time when increasing demands on highway infrastructure in post-WW1 years met with the relatively 'new' technology of reinforced concrete. Whereas many of the bridge illustrated have long been swept away in later reocnstructions it is remarkable how many still stand, in regular use, a centrury after construction.
The January 1924 issued looks at a number of bridges in Scotland. These pages look at two structures, the first being a bridge described as "Heriot Water Bridge", reconstructed for the Midlothian County Council under the superitenence of the County Road Surveyor, Mr R Moir, and with works carried out by Messrs Gray's Ferro-Concrete Co. It is not easy to pinpoint this bridge as names and locations are difficult to marry up especially as the A7 at this point has been extensively re-routed and reconstructed. I wonder if it is is not the bridge over the Gala Water adjacent to what was the site of the original Fountainhall station?
The second bridge was also a bit of a puzzle as this 'Gorgie Road' bridge, that I suspect spans the Water of Leith, does not align well with the current span that carries the A70 over the river. It may have been reocnstructed again, subsequently, possibly for the tramways extension? The bridge carries the then common ornate lamp standards that still exist, sadly disused, on many of the bridges in Edinburgh from this time. The building to the left, with the lion shields, looks interesting! The 'artistic' bridge was built to the designs of the 'late' City Architect, Mr George Morham. It's now been clarified that this is the bridge, still extant, that formed the entrance to Saughton Park and the site of the Scottish National Exhibition 1908 - the lion rampant decorating the now demolished entrance pavilion.
I love geometric patterns so when I saw all the triangles mirroring the other side, I had to capture it.
This world famous bridge was opened to traffic in Dec 2004. We called to have a look, shame there didn't seem an easy way to get from the valley up to road level. Called in the visitor centre for some souvenirs.
Wiki says;
The Millau Viaduct (French: le Viaduc de Millau), is a cable-stayed bridge that spans the valley of the River Tarn near Millau in southern France.
Designed by the British architect Norman Foster and French structural engineer Michel Virlogeux, it is the tallest bridge in the world with one mast's summit at 343.0 metres (1,125 ft) above the base of the structure. It is the 17th highest bridge deck in the world, being 270 metres (890 ft) between the road deck and the ground below.

A brochure issued by the then Regional Council of Lothian and their water undertaking the Water Supply Services Department who were based, just up the road from our house, at "Comiston Springs", the reservoirs up at Fairmilehead. It describes the "Megget Scheme" that was a major addition to Edinburgh and Lothian's water supply system that was formally inaugurated on 30 September 1983.
The scheme had first been proposed in 1963 by the old Edinburgh Corporation to augment the Talla Reservoir and associated aqueduct that had been built by the old Edinburgh & District Water Trust and opened in 1905. This had been scheme had been in the spirit of Victorian improvements in water supply both in terms of quantities and quality. The Megget scheme involved the headwaters of river catchments adjacent to that of Talla and again involved construction of an aqueduct, as seen on the plan, to transport water to Edinburgh for filtering and distribution. Work had commenced on the Talla Scheme in 1976.

The Centennial Bridge is the second major road crossing of the Panama Canal, the first being the Bridge of the Americas. (Small service bridges are built in the lock structures at Miraflores and Gatún Locks, but these bridges are only usable when the lock gates are closed and have limited capacity.)
The Centennial Bridge is located 15 km (9.3 mi) north of the Bridge of the Americas and crosses the Culebra Cut (Gaillard Cut) close to the Pedro Miguel locks. New freeway sections, connecting Arraijan in the west to Cerro Patacon in the east via the bridge, significantly alleviate congestion on the Bridge of the Americas.
The Bridge of the Americas (Spanish: Puente de las Américas; originally known as the Thatcher Ferry Bridge) is a road bridge in Panama, which spans the Pacific entrance to the Panama Canal. Completed in 1962, at a cost of US$20 million, it was the only non-swinging bridge (there are two other bridges, one at the Miraflores locks and one at the Gatun locks) connecting the north and south American land masses until the opening of the Centennial Bridge in 2004. The bridge was designed by Sverdrup & Parcel.[
Let me introduce Fidede, pronounced FeeDayDay one of a wonderful group of young people I met in Ottawa's Byward Market.
The group were working with their friend Wande on a fashion shoot for her new Stylist Business.
Fidede approached me to ask some questions about my camera equipment. A stunning woman in her own right, I took the opportunity to mention my project and that I was always looking for people to participate.
Originally from Nigeria Fidede is a second year Civil Engineering student at the University of Ottawa. Coincidentally she is also starting her own fashion blog, hence her keen interest in photography.
Obviously a perfectionist Fidede, has a real passion for knowledge and what it would take to improve her craft. I promised her I would send her some information on prime lenses along with the photographs I had taken of her.
A very spiritual person, Fidede wants to live her life according to her beliefs and along the way do what she can to help people.
A really sweet personality Fidede was very easy to talk to, she responded very quickly to my email with her photographs, thanking me very much, trust me the pleasure was all mine.
Thank you Fidede for taking the time to be a part of the Human Family Project.
Best wishes with your studies and your new fashion blog.
This is my 3rd photograph in the Human Family Project.

After more than three quarters of a century, this tower remains one of Chicago's most notable and remarkable architectural monument. This building was the product of an organized competition for the 'most beautiful and eye-catching building in the world' -- organized by the Chicago Daily Tribune. With its familiar gothic design, and coming up with a building that was more practical for the newspaper company -- it was John Howell's who got the first place award. John Howell would later build another iconic building too -- in New York -- the Rockfeller Center.
This building stands at 141 meters. Located at North Michigan Avenue, overllooking part of the Chicago River. It has been noted that this tower contains interesting stones included in its wall -- rock fragments of Rome's Colosseum and China's great wall. The building also has on display(not included in the walls), one of the many rocks taken from the moon.
