Bridges of Redwood, Yazoo River, Mississippi

For decades, drivers on Highway 61 (the Blues Highway) had to cross the Yazoo River at Redwood, Mississippi, on a handsome 1950-vintage steel cantilever bridge. Unfortunately, I do not have a photograph of the old bridge when intact. The old bridge was elegant in a mid-20th century industrial style, but no longer suited contemporary transportation needs. The two lanes were narrower than current standards, the bridge required expensive painting, and clearance was too low for some tall trucks.  Therefore, Mississippi Department of Transport (MDOT) built a modern concrete 4-lane bridge over the Yazoo a short distance south of the old structure. Rather than disassemble the old bridge, it was dropped in place using explosives on July 1, 2009. According to WJTV television, "The bridge was blown up at 7:50 a.m. and the blast was fueled by packets of explosives placed at strategic points by contractor Key Constructors. Boats on the Yazoo were halted as crews cleared the waterway." I missed the demolition because it was not announced to the public beforehand, but I drove to the site a few days later.

This photograph shows the east approach with some of the structure still standing.

This is the center span lying in the river. It must have taken several days to remove the debris, during which barge traffic would have been blocked. The Yazoo is a Federal navigation project, but commercial tonnage is low and the channel is seldom dredged.

A short distance to the south, out of sight of the highway bridge, is this abandoned railroad swing bridge. It has been unused since at least the 1980s. A few years ago, I read that these types of bridges were slowly disappearing from the US landscape, but one is still here.

The tracks and ties were removed a long time ago from the west side of the bridge. This is an example of the immense engineering infrastructure built by the railroads in the early 20th century. For many years, the best and brightest engineering students went to work for railroads because they offered the most challenging careers.

Finally, a slightly off-topic photograph. This is the auditorium of the Radwood elementary school on May 7, 2011, when the Mississippi and Yazoo Rivers were at record flood levels. The school built temporary levees to keep out the water, and books, furniture, and other materials were moved to the auditorium, which was a bit higher than the other rooms. Fortunately, the flood waters did not reach the building and no equipment was damaged.

As a final example of bridges and railroad engineering, here is a monumental lift bridge on the Cuyahoga River, in Cleveland, Ohio. I have never seen this bridge in use, and it is rusting and deteriorating. But look at its massive construction.  I hope it will preserved as a mechanical or civil engineering monument. Also, look to the lower left and you can see a swing bridge similar to the one at Redwood.

Vicksburg Panorama 2004

This is an experiment, a panorama that I took from the roof of the two-floor brick building at the NW corner of Crawford and Monroe Streets. I am not sure if it will open up as a wide file in this blog software.

The view pans from the west to east and finally to southeast. The date was October 3, 2004. Little has changed from this viewpoint since I took this photograph. The YMCA is in the process of being repaired, including the tile roof.

Technical:  A friend loaned me a Canon PowerShot G6 digital camera.  I merged the frames with a Canadian panorama software, PanaVue ImageAssembler.

Amazing masonry: City Hall, Philadelphia

Philadelphia went through a rough time from the mid-1960s through the 1980s (I am not singling out Philadelphia; many American cities were pretty grim during that period). But today, downtown Philadelphia is reasonably clean, interesting, and fun to visit. It shows what can happen when a municipality does not allow urban decay to set in and take over.

The centerpiece of downtown is the monumental Empire-style City Hall, which occupies an entire block in the center of the city. According to Wikipedia, the building and was constructed from 1871 until 1901 at a cost of $24 million. It was designed by Scottish-born architect John McArthur, Jr. in the ornate Second Empire style. With almost 700 rooms, it is the largest municipal building in the United States and possibly one of the largest in the world.

This is a circa. 1899 photograph from the Library of Congress Prints and Photographs Division, Washington, D.C. (online here).




Here is some of the architectural detail and statuary. The latter two photographs I took from my room in the Marriott Courtyard Philadelphia Downtown hotel. It would be hard to find a more convenient location.



The tower is quite an edifice, but unfortunately its impressive size is somewhat diminished by the tall office buildings nearby. The antenna spire is 548 ft up, and Wikipedia claims that from 1901 to 1908, this was the tallest habitable building in the world (the distinction is in contrast to religious buildings like cathedrals and monuments like the Eiffel tower). William Penn is on the top, and he is 11-m tall and faces northeast.

According to the Wikipedia article, in the 1950s, city fathers considered demolishing the city hall, but the cost would have been too high. I do not doubt this story; the 1950s may have been the low period in the American consciousness pertaining to historical preservation. Recall this was the era when the so-called "modern" interstates were slashed across cities, often chopping up historic ethnic neighborhoods. Suburbia and white flight reigned supreme during this period, and inner cities were left to deteriorate and fester. See Building Suburbia, Green Fields and Urban Growth, 1820-2000 by Dolores Hayden for more details of the suburban flight and its consequences to American cities. Philadelphia's revived downtown shows that many people are finally returning to traditional cities, although the McMansion orgy of the 1990s-mid-2000s demonstrates a recent and gross extreme of the suburban flight trend.

Many other historical building around City Hall have been restored. Good for Philadelphia!

Even the streets have some interesting architectural elements.

This is the view east towards the Delaware River. The S.S. United States is moored at Pier 84 (the red funnels are barely visible in the photograph to the right).

This is the Capogiro Gelato & Sorbetto shop. It has some of the best gelato I have ever savored. Late evenings in summer, it is mobbed with students, businessmen, tourists, and local residents. I spoke to the owner one evening, and he said he toured dairy farms in Lancaster County to look for happy cows (in a similar way, that is why milk and butter is so good in France and Switzerland - the cows are happy).

Industrial archaeology: Redstone Quarry, North Conway, New Hampshire

New Hampshire is known as the "Granite State," and no wonder! There are granite outcrops throughout the state. Since the 1800s, quarries in New Hampshire and adjoining Vermont have provided hard, durable, and beautiful igneous rock for buildings, street paving blocks, monuments, and breakwaters throughout the east coast and even internationally.

Redstone Quarry, in North Conway, operated from 1887 until 1948. The remnants of machinery, derricks, and buildings constitute one of the more interesting industrial archaeological sites in New Hampshire. The most detailed description of the site is at the excellent WhiteMountainHistory.org web site. Some fascinating pre-1948 photographs are posted there.

The Redstone Quarry is at the base of Rattlesnake Mountain in Redstone (part of the town of Conway). The woods have grown so thickly, there is little to see from the highway, and you have to walk on dirt paths to see the remains.

One of the few standing buildings is the old latrine and bath house.

Further uphill is the blacksmith's forge and tool conveyor belt. I am not sure of its function, but the little buckets are so sturdy, I assume they were designed to hold hot objects. Possibly tools went through a quenching bath after they had been sharpened or heated.

This is the remains of a boiler. I have not seen the engine house, which would have contained larger boilers, but the White Mountain History web site (link above) shows a photo of a collapsed roof.

Now we come to one of the most interesting sites, the machine building that housed the polishing rock lathe. The wood building is incomplete and is missing some of its roof. I am not sure where the boiler building was located that provided power for the lathes, but it must have been nearby.

This is the 5-ft Face Plate of the polishing lathe and the spindle to hold a rotating column of granite. Can you imagine polishing a column of rock over 5 ft in diameter? Astonishing what craftsmen could do a century ago with equipment that we today consider primitive.

Outside on the ground are remains of the rough turning lathe. You can see where belts (leather?) would have run across different-size pulleys to provide power.

Look at this heavy-duty universal joint, an example of precision machining from almost a century ago. This is how we built a nation: hard work, pride, and precision workmanship.

Not far away in the woods are mounts for wood booms, used to swing rock around the work site. I read that the spruce booms came from the Pacific Northwest on special railroad cars (at that time, timber of sufficient size no longer grew in the US Northeast).

Walk further uphill and you reach the pink quarry. The pit is filled with water, but some of the booms are still standing!

Much of the debris in the pink quarry has tumbled down and is highly unstable. The clean rock face gives you an idea of the quality of the granite from this source.

As you walk west back to town, you come across a dormitory building in surprisingly intact condition. But vandals have added artwork to the inside.

There are examples of the pink granite all around North Conway. This planter is made from pink slabs.

And you see granite fence-posts in town and in area farms. No danger of these posts ever rotting.

This is the Hale cemetery on West Side Road, near the town of Conway. Look at the size of these remarkable granite slabs used as a wall. These may be grey granite from another site, but it was difficult to tell in the waning evening light.

This is a 1920s photograph of a rock lathe from the web page quarriesandbeyond.org. Notice the stoneman is not wearing eye or head protection. Many of these stone workers died young from silicosis, a terrible disease.

On a more cheerful note, autumn in New England is spectacular. The changing leaves are a visual delight. If you have never seen them, you must make this a life goal. This is Pudding Pond, and the tracks once served the Redstone Quarry.

These are digital files from a Panasonic G1 digital camera with 14-45 mm Panasonic Lumix and 9-18 mm and 40-150 mm Olympus lenses, tripod-mounted. I thank my North Conway friends for showing me these unusual sites. I have some older medium-format film negatives of the quarry that I need to scan and post some day.

Update Nov. 2019: I scanned my 2003 medium format film negatives and wrote a new article on Redstone Quarry. Please click the link to go to the new article. I thank all you readers.
