Lucy Jefferson Lewis Memorial Bridge

Historic Lucy Jefferson Lewis Memorial Bridge on U.S. Hwy 60 over the Cumberland River in Smithland, Livingston County, Kentucky. The Warren through truss bridge was built in 1931 by the Nashville Bridge Company.


This post alerted me to this bridge replacement project:
Marcus Hinman posted two photos with the comment: "M/V Miss Deanna and M/V Maverick topping the bridge around this afternoon in Paducah."
David Miller: Is that the bridge that's going up on the cumberland?

Obviously, the approach spans for the old bridge used steel girders whereas the spans for the new bridge use concrete girders.

$63.6 million contract awarded for U.S. 60 bridge at Smithland
[The article called it a "continuous truss." But a truss with just two piers can't be continuous.]
"Initial work at the site will include a significant maintenance project on the existing 89-year-old structure."

The new span is 700' long and the deck is 40' wide with two 12' lanes and 6' shoulders. That will allow most farm equipment to share the bridge with other vehicles. (The old bridge is 20' wide. Some farm equipment would fill up most of that width.) [wspd, this article also has a time-lapse video of the construction.]

The steel truss of the new $63.6 million Cumberland River bridge rotates in the Tennessee River just off-shore from the Paducah-McCracken County Riverport Authority. The truss must be turned six times during construction. It will then be floated to Smithland, Ky., for installation. (Photo by Scott Swamback/American Bridge Company)
[The 40' wide deck is in a 48' wide truss.]
"Jim Smith Contracting Company and American Bridge Company chose the Paducah-McCracken County Riverport Authority as the construction site in August in part because of the capabilities of its Comansa tower crane. The site is also rarely affected by high-water conditions, allowing work to continue even when Mother Nature might otherwise interfere. The first piece of structural steel was placed September 9."
[This project is evidently too small for the American Bridge Co. to mention on its web site.]
 
This must be the "Comansa tower crane."

Four New Bridges for a new Villers Island In Toronto, ON

(Satellite)
Janey Anderson posted
TODAY'S 2021 HOT PIC GOES TO DAVE YAGER TRANSITING BEAUHARNOIS LOCK ON MCKEIL TUG LOIS M.  All the Toronto bridges coming from Halifax brought excitement to the Seaway, but the second one with Captain Dave Yager on the lead tug Lois M. was a real crowd favourite. He says he "never minds honking for kids or Junkies". And the fun thing about Dave is, we never know what McKeip ship or tug he'll be on next! Cheers Dave - thanks for all the good times in 2021!
We welcome your 2021 pictures of the Toronto bridges in transit!

Before discussing why there is a bridge in a lock, I need to provide some background information about a waterfront project in Toronto that requires four new bridges. Toronto is putting a river back into its waterfront to reduce flooding and to turn an "underused" industrial area into "25 hectares of publicly accessible greenspace and parkland." [PL-about] The best way to understand the project is to look at before and after images. Unfortunately, the east/west dimensions of their map don't match the satellite image so I can't get an exact comparison. But you can see the new kilometer-long river valley with a new mouth for the Don River that is going to be dug between the Keating and Ship Channels. As part of the project, they are building a new Cherry Street west of the existing street.

Satellite, before

Map, after

Their spin on the cost is that it "will contribute over $4 billion to the Canadian economy." [PL-why]

This image finally helped me understand why they would dig a river. The parkland is a side-effect of the development. More prime real-estate near downtown is the real reason. They want to create a flood-free Villers Island for a bigger downtown. This image also shows the four new bridges that are needed to provide access to the new Villers Island.

It is a little disconcerting that the same web site has different images of what the new river should look like. Since this plan would require five bridges, it must be an obsolete plan.

The Jan 2022 satellite image still has the old trunnion lift bridge, but some photos of the replacement bridge have been uploaded.

But they are still building the new Cherry Street so the old trunnion bridge is still being used.

Janey Anderson posted three photos with the comment:
More News for Opening Day - McKeil Spirit is delayed leaving Toronto due to a problem with the bridge.
She's been laid up at Leigh cement in since 28.02.22 and expected to leave for Picton possibly Friday as long as the parts for the bridge arrive - TBC.
The Cherry Street Strauss Trunnion Bascule Bridge is located in the Port Lands and carries Cherry Street over the Toronto Harbour Ship Channel. It has to open to allow ships to access the channel and the turning basin beyond.
The bridge was built in 1930 by the company of Joseph Strauss and the Dominion Bridge Company. The north side of the bridge has 750-ton concrete counterweights that allow the bridge to pivot to open.
The city spent CA$2.5 million to refurbish the bridge in 2007. The Toronto Port Authority made further repairs from December 2012 to September 2013 at a cost of CA$2 million.

Leslieann Lafosse: Where are those new sections that sailed up from Dartmouth going, is it not down around there somewhere?

Dennis DeBruler replied to Leslieann's question
One of the four bridges will replace this one and another will carry Cherry Avenue across the new river that they plan to dig.

I'm wondering what is going to happen to the cement facility.



This photo of the new bridge from the old bridge shows that it is still up on its jacks after it was floated into place.

A Bridge Collapsed in Pittsburgh, PA at 6:30am, Jan 28, 2022

(Bridge Hunter; Satellite)

There were no fatalities even though there were cars and an articulated bus on the bridge when it fell.

But this comment did catch my eye.
Dawn Renee commented on Brian's post
Yeah, they knew that bridge was damaged for years. So scary.
[So the bridge inspectors and repair engineers didn't think that diagonal member was carrying any compression forces? Cables help only with tension forces.]

Richard Butterworth commented on Brian's post
The average fully loaded articulated bus weighs between 28 to 32.5 tons. With a bridge weight limit of 26 tons, the bus probably shouldn't have been there in the first place.
[I wonder what the fine print for "load limit" is. That is, 26 tons in how many feet? An articulated bus may be long enough that it legally spreads its weight out over the bridge.]

"Design: Batter-Post steel rigid frame, constructed from weathering steel (also known as Cor-Ten steel)" [BridgeHunter] Some BridgeHunter comments indicate that Cor-Ten has proven to have a problem with salted roads.

The Chicago Tribune reported that the most severe condition of those hospitalized was "fair." I'm not going to bother to read any more of the media reports since I know there were no fatalities. I'm sure they will report the accident is under investigation. I will record the NTSB URL that Nathan Holth provided in BridgeHunter, https://www.ntsb.gov/investigations/Pages/HWY22MH003.aspx, so that eventually I can access some real information.

I capture the rating of the bridge so that I can compare it to the I-80 bridges in Joliet, IL.
BridgeHunter

I-80's report:
BridgeHunter-I-80

If this collapsed bridge was "just" poor, then why are vehicles still allowed to drive over a bridge that is Critical? Especially since normally there is a continuous line of trucks over the whole bridge because of the intermodal yards south of Joliet and the congested traffic on the bridge. Secondly of all, how can the individual numbers for I-80 be worse than the Fern Hollow Bridge but the Sufficiency Rating is more than three times better? If the trillion dollars is allocated based on Sufficiency Rating, then I-80 is screwed. (I had seen a Sufficiency Rating of 6, which is "intolerable." Who changed the 6 to 60?)

1929,1982 NS/Southern Bridge over Great Ship Lock Canal in Richmond, VA

(Bridge Hunter; no Historic Bridges; no B&T; 3D Satellite)

"Built by Southern Railway 1929, gears removed and bridge welded into place 1982." [BridgeHunter] "The lift bridge...was built by the Norfolk and Southern Railroad in 1929 to serve the paper mills along the Pamunkey River at West Point." [hmdb

We are in Richmond, VA on March 9, 1991, looking through the Norfolk Southern bascule bridge on their line to West Point. Running westbound on the former C&O James River Viaduct is eastbound CSX manifest R300 with two C40-8's. Confused? Q300 came eastbound into Fulton Yard on the former C&O. Once at Fulton, the power ran around the train and headed back west to Rivanna Junction and the former C&O Piedmont SD, and then ran a short distance to AM Junction where it headed north on the former Seaboard to South AY interlocking on the RF&P. There it turned south on the former ACL enroute to Portsmouth, it's final destination. Add to that, helpers are required between Fulton and South AY interlocking. This move is still performed several times a day with everything from manifests to unit coal and grain trains. Photo by Stan Short.

Nobody ever shows this area from this angle.
Vincent Corbo: Probably because of the now present no trespassing sign.

I discovered this bridge while researching the CSX/C&O James River Viaduct.

1960 Ogdensburg-Prescott International Bridge between New York and Ontario

(Bridge Hunter; Historic Bridges; no B&T; Satellite)

"The Seaway Skyway is one of the longest bridges over the Saint Lawrence River. It is also one of the most unusual. The Seaway Skyway has a main span that is a suspension bridge supported by Warren pony trusses. However, the bridge also features an extensive approach system composed of a variety of deck truss types. Additionally, the entire bridge has a steel grating deck instead of an asphalt surface, something that is generally only found on historic truss bridges and moveable bridges. It is even more uncommon for a steel grating to be found on a suspension bridge." [BridgeHunter]

"According to the American Bridge Company, the main towers for this bridge are 243 feet (74 meters) tall. The cable bents are 106 feet (32 meters) tall. The truss spans are 15 feet (4.57 meters) deep and 36 feet (11 meters) wide. The two main cables are 11.75 inches (286 millimeters) in diameter composed of 37 wire rope strands. The main cables have an aluminum filler and wrapped with number nine wire." [HistoricBridges]

None of the street view car drivers were willing to go through customs so I can't get a photo of a tower using street view. Fortunately, one of the many photos Jann took while on a boat was of one of the towers.

HistoricBridges points out that this bridge uses cable bent piers to reduce the height of the anchor piers and that the approach has a curve. One of Jann's photos captures both of these features.

Steel Dynamics Inc. (SDI)

This is a topic that I remember researching, but I evidently never wrote any notes. From memory, SDI started with a greenfield plant near Butler, IN, that produces steel coils. It expanded with another plant near Columbia City to produce structural and rail products. And its headquarters is in Fort Wayne, IN.

They have obviously expanded considerably from those two plants. Their steel mills use electric arc furnaces (EAF) and continuous casting. OmniSource is a wholly-owned subsidiary that handles scrap metals and Millennium Building Systems is their fabrication operation that "produces trusses, girders, steel joist and steel decking products" that are used in the building industry. [SDI-history] Given the Minnesota Operations, I presume they now also make HBI to feed their EAFs. That makes EAF steel competitive with blast furnace steel in terms of purity. (Each time scrap steel is used, more impurities are added to the next generation of steel.)  I could not find much information on their Iron Dynamics.
SDI-products

I've noticed that most of  the information on their web site is stale because it stops at 2014. 
SDI-history

SDI-product-guide, p15

A good video. Specifically, it is a professionally narrated video of equipment operationing within the factories. And it starts with no background music. When they did add background music, at least they kept it in the background. The concern about safety is needed. They have had five workers killed since 2001. [WANE

[I presume these are the two Electric Arc Furnaces (EAF) in their Butler mill.]

In addition to their original plant in Butler, they bought a flat-roll plant in Columbus, MS from Severstal when they exited the North American market, and they are building a new one in Sinton, TX.
