Now we’re just 50 yd/ 46 m to the north of the Des Plaines River overlook shown in Part 1 of this album. And we’re facing due westward.
Behold one section of the Prairie State’s most historically significant built waterway. It’s the Illinois & Michigan Canal, often just called “the I&M.” In future posts we’ll be canoeing down this rather untended segment of the canal to explore one of its aqueducts and locks at the settlement of Aux Sable. For now, however, let’s stay put in McKinley Woods and consider the I&M's history.
In Geology Underfoot in Illinois I describe the canal as “a game of sixes” for the simple reason that it was generally designed to be 60 feet wide at the surface, 36 feet wide at channel bottom, and 6 feet deep when filled. (The metric equivalents: 18 x 11 x 1.8 m.) Begun in 1836 and not completed for another 12 years, the I&M runs a total of 96 mi / 155 km, from Chicago’s Bridgeport neighborhood all the way down to its merging with the Illinois River at La Salle.
A lasting monument to the great effort and sacrifice of a diverse workforce—a tough, hard-drinking, and often rambunctious assortment of “navvies” of Irish, German, French-Canadian, and other ancestries—this massive construction project took a deadly toll. Hundreds of laborers, desperate to earn a living and find a home for their families in a new and alien land, lost their lives in mishaps and from diseases spread all too readily by poor sanitation practices. In an age before steam shovels, jack hammers, and dynamite, these workers, fueled by daily rations of whiskey and salt pork, used hand tools and gunpowder to excavate the waterway.
In places like this, the navvies dug through relatively yielding Quaternary glacial and fluviatile sediments. But farther up the Lower Des Plaines Valley, they had encountered Regional Silurian Dolostone bedrock at or very near the surface. Excavating through that was much harder work. But in the process of their doing so Chicagoland’s great native building material was discovered, first quarried in commercial quantities, and barged up the I&M in special “stone boats” to the growing metropolis.
While the I&M soon had to contend with a very powerful competitor in the form of railroads, it managed to remain in operation till 1933. Throughout it was a great boon to farmers and manufacturers eager to cheaply transport their goods from the Illinois hinterland to the rapidly developing Windy City. And the I&M also provided America’s first reliable transportation link between the western Great Lakes and New Orleans and the Gulf of Mexico.
If you’d been standing here during its heyday, you would have seen a steady succession of canal barges plying the tranquil waters of the I&M. At first, these craft, specially designed for the waterway’s dimensions and locks, were pulled by mule or horse teams that plodded up the adjoining towpaths. Later, though, they were steam-powered and hence self-propelled. In any case, they were the very essence of laid-back travel. Passengers could easily jump off a barge and walk alongside it on the bank for a long spell, and then step back on. In these latter manic days, that leisurely mode of progress sounds idyllic.
One of the most interesting aspects of this portion of the I&M is its water height and close proximity to the Des Plaines and Illinois Rivers. The former stream is visible in this shot straight ahead and just beyond the narrow strip of trees that also contains the tow path. As you canoe down the canal, you see that its surface sits 5 or 6 feet (1.5-1.8 m) above that of the river. It's a bit disconcerting to look down on it as you paddle along.
The reason that the Des Plaines and Illinois themselves could not be used for boat traffic was simple: they contained shallows and rapids unaddressable by nineteenth-century civil engineering. And then again, a narrow canal is much easier to maintain and keep free of ice jams and snags than a broad natural river.

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.

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.

The new underground line between Washermanpet and Korukkupet readied by the Chennai Metro Rail Limited. This line included two station as part of Phase 1 extension to Wimco Nagar. The line will offer the residents of North Chennai neighbourhoods access to the transport system. It is expected to be ready in 20 months after contract are awarded.
2 kms of the line will run beneath the northern suburbs of New Washerman pet and Korukkupet. The alignment from Thyagaraya College to Korukkupet Junction have been formed up. Also, authorities have marked areas of potential impact of work on the buildings around proposed stations and tunnels.
According to sources, the silty clay soil will make it easy for boring machine to cut through. However, as the stations have to be built around the 2 km stretch, which is extremely congested, the underground stations will be tough. Phase I of the extension line will begin at Washermanpet underground station. This is part of the Airport - Washermanpet corridor. The tunnel for the line will begin near the Mint flyover. This will be bored under the railway line to Beach station.

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:

This photograph is a view of the bottom of the metro shaft at Argyle St. in Gateshead.
It was taken at some time in 1975.
The photograph is taken from a collection of black and white contact prints documenting the development of the whole of the Metro System in Tyne and Wear.
The images are taken from the Mott, Hay and Anderson Collection, consulting civil engineers responsible for the Tyneside Metro light rail system and the Tyne pedestrian, cyclist and vehicular tunnels.
Most of the photographs were taken by Amber Film Associates and Lambton Visual Aids, 5 and 9 The Side, Newcastle.

Facing east-northeastward at the northernmost section of Minnesota Point. Beyond it stretches the mythic expanse of Lake Superior, today in an unusually beatific mood. Mariners, be not deceived.
The bridge with its towers, high trussed frame, and lake-facing jetties is visible at left, between the sun shimmers on lake and harbor.
This shot, like two others posted recently, was taken from Enger Tower. It puts one of my favorite bridges in its proper natural context: as one small, manmade section of the great baymouth bar that protects the harbors of Duluth and Superior, Wisconsin. For a discussion of this striking coastal landform, see "Geology of Minnesota's North Shore, Part 1."
Of course, if you drive directly up to the bridge on Duluth's Lake Avenue, it looks much more imposing than it does here. In fact, it's such a lovely piece of civil engineering that it's worth a trip from the antipodes just to see it. At least if you're a pontiphiliac. And the best time to walk or drive across it is about fifteen minutes after sunset, when its lights have winked on and the water around it still holds the last crepuscular glow of the fading sky.
Following photos of this set will demonstrate that this span is a vertical-lift bridge. This fairly uncommon design features a moveable central roadway section that is hoisted, still in its usual horizontal orientation, almost all the way up its towers' height, to provide clearance for vessels large and small.
However, until it was refitted in 1929 and 1930, the Aerial Lift Bridge had an even stranger way of doing its duty. For it was a transporter bridge that had a large gondola, suspended by cables attached to the frame overhead. For a quarter of a century the gondola faithfully carried countless loads of people and vehicles from one side of the channel to the other. Each one-way trip took about a minute.
