1937 Aban/.../ACL+Road Bridge over Intracoastal Waterway at Myrtle Beach, SC

(Bridge Hunter; Historic Bridges3D Satellite)

When it was built, it carried the road as well as the railroad. It seems that plate girders instead of trusses are used with rolling bridges more frequently in the South than in the Midwest.

We can get a nice view of the arc member on which it rolls and the horizontal rack and pinion gear that is used to raise it.

Ted Gregory posted three photos with the comment:
Quite an imposing structure sits across the Intercoastal Waterway.
This bridge is ACL heritage and was used to reach Myrtle Beach.
Hoping RJ Corman, which is in the middle of upgrading this line to the west and north, sees value in rebuilding this bridge and restoring service the remainder of the way to Myrtle Beach.

[The comments indicate that the only industry that was rail served on the other side of the bridge is a lumber company and that they now transload the lumber from the mainland side.]

The early history of the automobile in Chicago

Old photos of streetcar scenes and depots (e.g. Dearborn and Wells Street) provide insight into how the horse was replaced by the internal combustion engine on the city streets. These notes save some comments made on a Facebook share that describe the introduction of automobile and bicycle manufacturing in America.

  • Not only has Lake Park been built with landfill between Michigan Avenue and the IC tracks, but they have planted some trees.
  • There are many boxcars on the IC tracks.
  • The Interstate Exposition Building has been torn down so that they can build the Art Institute for the Columbian Exposition of 1893.
  • A pier exists at the IC Van Buren Street Station for steamboat traffic.
  • There are no cars on Michigan Avenue. It will be a couple of more decades before they start to become significant.
  • Both grain elevators exist on the south side of the river.
  • There is still heavy industry on the north side of the river.
  • Fill for Grant Park has not started.

US Steel Midwest Plant in Portage, IN


Allen Sydow posted two photos with the comment: "USS Midwest plant."


From their web site:

The Midwest Plant, a finishing facility that operates as part of Gary Works, is situated about 10 miles east of Gary in Portage, Indiana. Principal products include tin mill products and hot-dip galvanized, cold-rolled and electrical lamination steels that are used by customers in the automotive, construction, container and electrical markets.

Update Sept 27 2021 4pm On Indiana Dunes National Park shutting down its beaches and a northwest Indiana water utility shut down an intake facility after an orange substance apparently spilled from a U.S. Steel plant into a Lake Michigan. This is just an update from yesterday the orange cloud is gone now.
Russell Hedgepeth: They just got fined a month ago for a million for a leak in 2017. And had six or seven spills since then. I for one I'm tired of big corporations having control of our lake fronts....These are only ones that are known. No telling what else these mills are putting in there.
Susan Urena: Russell Hedgepeth our water intake is there and they always wait a few hours/days to alert the water company. Plus the treatment doesn’t remove metals etc. only biological crap.
Ed Stojancevich: Getting ridiculous. Imagine all of the [stuff] we DON'T know about.
Thomas Labus: Matt Vdhd yup. And I'm sure it is less than it would cost to properly dispose of it, so they intentionally chose this way instead. $600k is nothing to them.
Scott Duszynski: WGN Morning News reported this morning that this is the 25th spill from the mills since 2018 and they've been fined every time. Apparently that isn't working out too well.
Norah SCylla: Likely hex chromium out of the tin division...again!!
Tyler Grzesik: Was there yesterday it was bright orange.
Gal Logan: Where's the booms

USS/Midwest Plant recently had to pony up $1.2MM for a discharge of hexavalent chromium.
Ernie Carey Jr: With the price of hot band right now they don't care.
[They need to put the plant manager and a USS vice president in jail for 5-10 years.]

Two photos by Danny Lunn that shows the discharge orange.
Kevin Studley: An orange color suggests a possible leak of hexavalent chromium -- a highly toxic carcinogen, and one of the more toxic chemicals used in the steel mills.
I know. I used to work around hexavalent chromium and one or more foreman sought to fire me for complaining about mishandling this chemical. I stood my ground. They lost, we won -- but apparently those lessons have been forgotten. There was another hexavalent chromium spill about 4 years ago.
Somebody stand up and prove I did not risk my job for nothing -- that clean drinking water still matters.

Lost/PC/NYC Bridges over Chemung River in Corning, NY

19th Century: (Bridge Hunter)
20th Century: (Bridge Hunter; Satellite, they removed the piers and abutments)

Steuben County Historical Society posted
[Tropical Storm Agnes]
As the rivers rose in 1972, someone figured that 15 loaded coal cars would help anchor the Penn Central Railroad bridge over the Chemung River -- you can see the results. Bringing down a structure of this size suggests the horrifying force of the waters, and damage such as this did in several railroads here in the northeast. We're looking northward here -- in the background we can see the Corning Glass Works office tower, and the Corning Glass Center/Corning Museum of Glass.
Jim Kane: The Glass Museum had a "High Water Mark" way up high on the wall.

Octagon Fad shared
Fran Koch: seeing the downtown area firsthand after Agness........was so sad. And now, Corning has built a new facility in North Carolina.
Tim Fuller: The purpose of putting loaded cars or locomotives on flooding bridges was to reduce the likelihood of damage from the lifting effect of the moving water. Any surface in a flowing medium has a lifting effect dependent on the density and speed of the flowing medium - think back to your childhood and putting your hand out the car window to play with the air slipstream.
The major force keeping all bridges in place is gravity, so to counteract the lift forces of the moving river water, railroads routinely increased the weight on the bridge to increase the downward gravitational force.
Boaz Miller: Tim Fuller, well, fluid dynamic lift requires the fluid above and below the surface, so the hand in the airstream doesn’t work here.
It isn’t actually a lift; it is the tremendous shearing force due to fluid drag and lateral pressure on the support structures. Water is a very dense, heavy fluid and even a slow current can exert a massive shearing force against a stationary structure.
Bob Mason: Boaz Miller you are correct. Additionally with that much flow there is often some major scour occurring. If the water scours out a big enough hole and undermines the pier or abutment, the piers will topple over unless they are anchored to a cement pile cap on driven piles.
Bill Poole: The IHB does this frequently on the bridge over the DesPlaines River located @ McCook, Illinois.
Dennis DeBruler
There are several photos before and after it collapsed on this page:
The after photos show a lot of debris against the trusses and the piers are tilted because of scouring and/or lateral pressure. The debris would magnify the lateral force of the flowing water against the truss.

Did the piers tilt because of scouring or because of the tremendous lateral forces exerted by the flowing water against the tree debris against the trusses? Or because of both?

1907 RCP&E/CP/DM&E/C&NW Bridge over Missouri River at Pierre, SD

(Bridge Hunter; no Historic Bridges; John A. Weeks IIISatellite)

RCP&E = Rapid City, Pierre & Eastern Railroad, 2014 to present [G&W]
DM&E = Dakota, Minnesota & Eastern Railroad, 1986-2008 [american-rails, icerail]

I had already encountered the RCP&E because one of their bridges got washed out in 2019. So I had already sorted out the history of the corporate names for this route.

Why am I doing notes on yet another swing bridge? Because this swing bridge means that steamships used to come at least this far up the Missouri River. Since the Gavins Point Dam does not have a lock, now none of the Missouri River is navigable in South Dakota.

John Weeks, this web page has a significant history of the bridge

1906 BNSF/GN Trestle over Midvale Creek in East Glacier Park Village, MT

(Bridge Hunter; no Historic Bridges; Satellite)

What are the odds that a street view would catch a light move?
Street View

Michael Krejci posted two photos with the comment: "I found this interesting. This is in East Glacier Park, MT. where they get very high winds. Trains were blown off the track here several times, then the RR installed wind breaks on the trestle and that solved the problem."
[There were some comments about the bridge being able to handle the additional lateral wind load.]
Andrew Matarazzo: William Phebus don't forget that the lateral oscillation of a steam locomotives side rods was usually calculated as part of the load on RR bridges. I'm sure someone performed a load rating to ensure it could handle the wind loads in lieu of daily steam traffic.
Robert Barker: cooper e80 live load design. I’m sure it will be fine.
Chad Hansen: Maintained that for awhile. Times they have to stop stacks cause of 100 plus wind gust.
Ben Cornelius: Amtrak’s Empire Builder on this route with its double-deck Superliner equipment has been held on occasion for 4-6-8 hours or more for the winds to diminish.
Billy Hallman: I wonder how many locomotive engineers were fired for train handling before they figured out it was the wind causing the derailments.
Gerald A. Edgar: Having stayed @ both E & W Glacier, & watching trains from the lodge @ W. Glacier, you can indeed get a vortex on that bridge given shape/direction of the deep valley. I encourage all of you to take the E.P. Builder there!
Ronaldo Pencato: Wind load is measured in Kips. Those wind screens don't put enough of a load on the bridge to matter. I build communication towers. We worry about wind load and sheer at elevation
Dave Stratton
A few miles East of there, SW of Browning, MT, the track turns North and South. It is on a fairly high fill and there use to be an anemometer that is tied into the signal system. If the wind speed was a predetermined speed (maybe 60 mph) It stopped trains.!3m1!1e3!4m5!3m4... [See photo comments below about the wind screen that is here.]
Bob Avritt: Used to have containers scattered along the big curve west if Browning, Montana as well.
Jerome M. Motter Jr.: It kind of solved the problem. We still have wind warnings and have special rules when they happen. That's not even the worst spot. Down in Browning there is an even bigger and longer wind fence.


Jerry Urfer commented in Michael's post
Browning Mt. wind fence BNSF Highline Sub. Was employed in this area for years, strongest wind I was in was 128mph. Both fences have worked as intended for the last 15 years.
Troy Gladle: I always thought those were for snow drift control.
[Snow fences are built away from the track so that the drift doesn't dump onto the track.]

Dominic Deeble commented in Michael's post
I head to Montana 2-3 times a year. Always hitting the BNSF Hi Line Subdivision. Browning has a fence as well. Pretty neat engineering.

Steel Mill "Cobble"

I've seen videos of something going wrong in a old bar or rod rolling mill and the bar "squirting" around the room. I always wondered why there were no panic-stop switches throughout the mill to stop it when things are going wrong. A comment on one of them called the resulting spaghetti of iron a "cobble." But then I forgot that term. Now I have again learned that term. This is the first time I have seen a coil rolling mill create a cobble. From some comments, it sounds like it is not a rare occurrence. I probably have not seen it because many mills have a "no camera" policy.

Mark Edmund DaSacco posted
A real nasty cobble that happened in the roughing mills. Both cranes had to hook up the heppenstahls to take it off the roll bed...
US Steel, great lakes works hot strip mill.
Michael Prihoda: What is and what causes a “cobble”?
Mark Edmund DaSacco: The front of the steel being rolled catches for some reason and it's going so fast that there's no time to stop it piling up behind. When it happens in the coilers at the end of the process when it's being rolled into a coil it's called a purot.
[Some comments indicate that if they are rolling cold steel or in the roughing mill (where the sheet is still thick), the cobble can cause damage to the equipment.]

I think this is the same mill, but a different cobble.
Mark Edmund DaSacco posted
Cobble in the mill.
US Steel, great lakes works, hot strip mill.
Michael OConnor: Making X-Mas cookies.
Kenneth Treharn: The old accordion trick. Sometimes they really pack them in if their slow on the Stop button. Pin that looper and get a hook to get the cobble chain thru then into the bull ring.
Tony Mason: I remember when the ETS line in Fairless had train wrecks. It was an all night job to get it back online.
Andrew Jackson: Pin that looper before you go in to clean that out! [Since the steel is under stress, I presume he means that there is a risk of the steel flying around after the cutting torch relieves the stress.]
Richard F Luzzi: I’ve seen em try to take too big of a bite at a seven stand and sheered a 2’ thick spindle and sent the gears thru the top of the gearbox. Awesome power from the motor room.
Andrew Jackson: Richard F Luzzi I’ve seen cold bumper slabs get ran into a roughing mill stand #1 and jam everything up. Talk about 12hours of burning.
Bill Beatty: Weirton used to run a lot of Stainless for J&L. When they wrecked it would take quite a while to clean up and repair any damage.
[It sounds like the production crew changes the work and backup rolls while the milwrights remove the cobble.]

Aiiiiight den.
Chris Judge: .Time to call the burn gang
Micheal Coff: We don't have a burn gang for this. Its just one guy per turn to clean up messes like this and do maintenance and roll changes.
Matt Burton: 84 USS Gary works? [Michael confirms this.]
Kipp Bell: At least it stayed on the table.
Derek Bakle: We all chip in to cut cobbles at Steel Dynamics Inc.
Joe Makarowski: Push it off, come ahead!!
Kenneth Treharn: I've seen lots of cobbles over my career. Less of a mess on that side of the finishing Mill than a "pile up" at the Coilers.
Thomas's Dallas: Blame it on the roll shop grinders.
Dominic Mosconi: Thomas's Dallas exactly what they did I was a roll grinder.
Richard F Luzzi: table hoods make it look like finishing mill runout table on its way to coilers but, the gauge looks a little thick. I served my Motor Inspector apprenticeship at the 84” Hotstrip USS while it was being built. Took 3 years before the first slab ran thru it.
Micheal Coff: Richard F Luzzi its the holding table. Between the rough and the FM. Good eye.
Bryan Wilt: Looks like money to me! (I work for a mill service company so we remove and process cobble and all the other revert from the mills)
Robert Washkevich: My grandfather's brother retired from the 56" hot Mill in '79 and when I talked to his wife , my great aunt, she knew about cobbles cause he would come home complaining about a "cobble". I worked in the 68" hot strip starting in '97 and many times they would side pull with the crane to get it out and I had to put the cable back in the sheave on the auxillary hoist.
[Search for "Groumoutis" to see a video of workers standing around watching a rod mill running bad. This is the type of video that makes me wonder why there are not panic-stop switches in the mill. Groumoutis adds "That one doesn’t compare to the one we called the super cobble. The super cobble was over 2000 feet of rebar. A electrician did a download and cause the pulpit to lose control of the shears so they never cut."]

Chris McNeal commented on Michael's post
Nothing like burning about an hour into the shift.

Alan Willis posted two photos with the comment: "Just a couple of these merchant bar mill cobbles!!! Never fun to clean up but cool to watch unravel."
Matt Mcguier: Kind merchant bar was that?
Alan Willis: Matt Mcguier 2x2x1/8” but still had 3 stands to make it through before the boo boo.

[At first, I could not figure out how the bar shot straight up. Then I noticed the crane hooked to the top of the bar. So this is a photo near the end of a cleanup.]

Comments on Allan's post

Now that I know the technical term for a rolling mill booboo, it occurred to me to do a search for "steel mill cobble" on YouTube. There were several results. This was the first one. I wonder if the glass on the pulpit would survive being hit by the cobble. (viewing length is 3:08)
