Flood of 2019: IAIS/Rock Island 1900 Quadrangular Trusses near Booneville, IA

(Bridge Hunter; no Historic Bridges; John MarvigIAIS Plans (but you need a login to access the info!); Facebook GroupSatellite)

This is a win-win posting. It not only shows the impact of the 2019 flood, it documents a double-lattice truss bridge that is soon going to be replaced. Note in the satellite image that the two eastern spans are normally over land. In these photos, water is under all four spans.

[The river is flowing fast. At least there are no ice slabs on it.]
A street view shows us a more normal river level.

I did not include the last two images because I recognized them as a copy of John Marvig's work.

The bridge is being replaced. Saving the satellite image because the truss has nice shadows and is probably going to disappear.

[The various sized augurs surprised me. Do they start with a small hole and then keep increasing the size until they get to the caisson diameter? Or are the caissons of different diameters? Or does the contractor bring all of his equipment to every site?]

I don't know what they are doing here. It is obviously of a smaller diameter. Note the poured caisson with rebar sticking out doesn't have any steel around it. Can they pull the steel shell back out and reuse them? Or did they cut off the top?

The above must be drilling a pilot hole because I think this is in the same location.

Chris C J Johnson Built in 1900 by the Chicago Rock Island & Pacific Railroad (CRI&P) and now used by The Iowa Interstate Railroad (IAIS).
Located just 1/4 mile West of the small town of Booneville, Iowa this bridge and its four trusses spanning 632 feet cross the Raccoon River.
Progress vs. History.
After 119 years-A new bridge will be built on the Southside of the old bridge and the old bridge will be demolished.

Chris C J Johnson Mike Brady My understanding is that IAIS is replacing and demoing them all...2019 it was the 1800’s era bridge over Walnut Creek in DSM.

Chris C J Johnson commented on the above photo
CRI&P Rivet Coal Fired Rivet Forge.
These rivets were heated and thrown to a leather or asbestos blanket held by the workers putting in the rivets with a steam powered hammer.

[There are several other photos recording the closeness of the two bridges. Chris commented: "A great challenge to the future demo company of the 1900 bridge being that close I would guess!"]
When I noticed that a pier seemed to be slanted in one of Chris' photos, I looked for it in street view. Srue enough, IAIS had to repair a pier damaged by the 2019 flood.
