Concrete Paving Before Ready Mix Trucks Were Developed

Before ready mix trucks were developed in the 1950s, a mobile mixer was run at the site. Contractors would typically lay a narrow gauge railroad along the work area to haul in the materials.

Bruce DeMaeyer This machine, a Koehring Mixer was a mainstay of concrete paving of this era, but what is particularly interesting is the use of a temporary rail line to haul the building materials to the site. Wonder why they did not use trucks?

Dan Bartlett Are they mixing that concrete on site do you suppose? So maybe supplies in those cars? Don't look like they wold work well with concrete.
Dennis DeBruler They are mixing the concrete on site. Here is another view of the Koehring Mixer and a supply train.

Remember that the tires on a truck in 1925 were thin and the engine was small. Truck development did not make ready mix trucks viable until the post-WWII building boom.
Rick Aylsworth I'm thinking the cars hold a batch of materials in proper proportion, and get picked up and dumped into the mixer.
Daniel Herkes Yes, that's correct. I used to operate a batch mixer and the cement, sand and rock came prepacked. Sometimes you can't get a truck mounted mixer where you need it.

Steve OConnor commented on the above posting
Road building was often done with temporary industrial railroads. The terrible condition of dirt roads during rain made truck traffic all but impossible. The solution was to lay tracks parallel to the road and run small industrial locomotives to shuttle concrete from a temporary concrete plant erected along the road.
Steve OConnor commented on the above posting
A train loading up at the temporary concrete plant along side the road bed. Ironic that these locomotives were building the very roads that one day would help put them out of business.

Tempe Town Lake Dam on Salt River in Tempe, AZ

(Satellite)

While studying UP's bridge that they damaged in Tempe, AZ, I noticed in a satellite image that Tempe had a dam to put a river next to their river parks.

Screenshot via tempe.gov
3D Satellite
I zoomed into the gates on the satellite map to verify that they can be moved to offer no resistance to the water during a flash flood. That is when I noticed that the gates have a design that I had never seen before. At first I had assumed that it was a rack and pinion drive. But then I read that this "is the country's largest hydraulically-operated steel gate dam system." [tempe.gov] In the screenshot above you can see the hydraulic rams. They are clearly long enough that they can be extended so that the gates lie flush in the splash pool. "Using hydraulic lifts, these gates can be lowered to allow storm waters to pass through and raised to capture the tail end of the flow to re-establish the lake. About two feet of water can pass over the top of the gates while they are in the fully-upright position....The cost of this project, including removal of the previous dam system, was approximately $47 million." [tempe.gov] The above video explains that the gates are also lowered when the Roosevelt Dam discharges water.

This new dam replaced a dam that used inflatable rubber bladders that was constructed in 1999. A lot of work was done to ensure that the town's water allocation stays in the river channel and doesn't seep into the surrounding land. On the west end of the lake, they used cement stabilized levees with a cement-clay cutoff wall down to bedrock. On the eastern end, where the bedrock is much deeper, they lined the Salt River channel with clay and concrete. The have also installed seepage recovery wells. They do have to consume their water allocations to compensate for evaporation losses. The gates must be able to be raised while water is still flowing over them to capture the end of a flood event to refill the lake. [water-quality] Much of the lining of the river channel had already been done before building the dams to avoid channel erosion during flood events. [original1, original2]

The harsh desert environment was hard on the rubber dam, so it was replaced with the steel gate dam in 2016.
water-quality
Evidently they have not had a major rain event since 2016 because the only image I have found of the gates being completely lowered appear to be during a gate test.
Screenshot via tempe.gov
And there is vegetation in the downstream riverbed. When I first looked at the satellite image, it struck me how low the flow of the river can get.
Satellite
Indeed, it can get bone dry. A construction video made a point that they installed a rubber strip at the base of the gates to help seal the water in the lake. That means that the water in the lake is stagnant. I wonder if they have a problem with toxic algae growing on it. [DeBruler]
Vijay pentapati, Sep 2016
Evidently the lake is big enough that it doesn't have problems with algae, but sometimes the spillway does. But the next decent-flow event will flush that algae away.
Minette WILLIAMS, Apr 2018
The heaviest operational flow that I found.
Greg Roberts, Mar 2017
Some construction photos

(new window)  One of the bladders erupted in 2010 and they lost the lake. Also, the lake is the town's water supply. So if the intake is near the west end, that would provide some flow in the lake even if no water is flowing past the dam.


I paused the video to read the river gauge. That is when I noticed the link and bracket next to the hydraulic ram that can hold the gate in the upright position. I assume this is in anticipation of the maintenance activity of replacing a ram. You can also see the slot on this side of the river gauge where they can install a bulkhead gate.
Screenshot

(new window)  Of particular note is the number of times the old dam had to release water and they had to pump the construction zone dry again.


(new window)  Installation of the first gate. The gates were evidently fabricated in two pieces.



Unlike the two dams in Michigan, the downstream Salt River can handle the full flow of the billion gallons that are normally in the lake. So loosing just one-fourth of the dam should not have caused any downstream flooding issues.

When PCL replaced the four rubber bladders, they also installed a sprinkler system to keep the rubber cool on hot days.

It appears they have had some local rains in the Summer.

1912 or 1915 UP/SP Bridge over Temp Town Lake in Tempe, AZ and the UP destruction of said bridge

(Bridge Hunter; no Historic Bridges; HAERSatellite)

The sources seem to be about 50/50 concerning the construction date of 1912 vs. 1915.

Second video in azfamily
[The derailment of about 10 cars caused the south (right side) span to collapse and a fire to break out.]
"Tempe officials said one of the derailed cars contained cyclohexanone, a pale and oily liquid that is toxic and flammable. It's used to make nylon and paint remover. HAZMAT crews placed a foam layer over the car to keep it cool and prevent any chemical vapors. The chemical is leaking into a storm drain that goes into the riverbed on the west side of the dam. Crews are testing the area and working to stop the leak. The other two cars on the train track were transporting chemicals but neither are a hazardous concern right now, the City said. It's unclear what impact the derailment will have on the wildlife in the area.
The cars that burned for hours were carrying lumber, some of which fell into the lake."
No one was injured. But the collapsed span was over a highway, so UP really lucked out.

The bridge had its annual inspection on July 9. UP had derailed a dozen cars on this bridge just last June 26. The temperature was 115. But I assume the rails are used to temperatures like that. [azfamily] I saved 12 posts from Facebook about this derailment. But I'm not going to look at any of them. I'm happy with the amount of information in this azfamily page that Bridge Hunter referenced.

This was when I realized that the collapsed span was over a highway.

And UP was lucky that their wood trestle escaped the fire. It looks like some utilities lost their  conduits.

Someone updated Bridge Hunter on the same day of the derailment. According to a comment, the bridge carries pipelines.

[Aug 12, 2020] The flood of rail traffic is about to begin...Frank Loulan I looked at the KJZZ news report and they just reported yesterday afternoon that the AZ Corporation Commission had given approval for the reconstruction of the bridge. Clearly the rebuilding didn't happen LITERALLY in a matter of hours. Either they were very slow in reporting or UP had been working on it all along prior to receiving permission from the ACC to rebuild!!John Ciolli Bill Chrisman it's 10mph right now. I was the 3rd train across it last night/morning. Frank Loulan I think you are correct, Charlie, as the previous speed limit was only 15 MPH around that curve on the north side of the bridge as I recall. (I still have some old timetables around the house here somewhere, but can't lay my hands on one at the moment to confirm that.)

You may have seen coverage of this July 29 derailment and fire on the Union Pacific Railroad's Tempe bridge. Several cars of a Tucson-Phoenix train derailed on the approach to the south end of the bridge with several plunging onto the road and parkway below. No one was injured, but the south end of the superstructure was so badly damaged that UP decided to blow a portion of the bridge up and rebuild it rather than attempting to extricate the remaining derailed cars.

safe_image for Regulators approve repair of Tempe Town Lake bridge damaged by train derailment
The bridge is part of a spur route off UP’s California-to-Texas main line across southern Arizona, and the railroad said it needed to reconstruct the bridge to restore service to metro Phoenix. Since the derailment, UP has routed some of its freight trains into metro Phoenix by using a Burlington Northern Santa Fe branch line that connects with the competing railroad’s main line across northern Arizona. The railroad will pay for reconstructing the bridge and the damaged parkway, the commission said. [And, of course, the NTSB is still investigating.]

I think the 2000 bridge is interesting because they used a through truss span over the navigation channel. Were tied-steel arch spans still in development a couple of decades ago?

Forgotten Railways, Roads, and Places posted
The Mark Twain Memorial Bridge spanned the Mississippi River, connecting Hannibal, MO with the State of Illinois at Aladdin. The bridge was a Public Works Administration project, opening in 1936, coincidentally as part of US-36.
Before the bridge was built, automobiles could cross the Mississippi River at the nearby Wabash Bridge, which was built, and remains, as a railroad bridge. Originally opening as a toll bridge, the tolls were removed in 1940
In 2000, the bridge was demolished and replaced with a new bridge of the same name, carrying the newly-extended I-72 into Missouri, as well as US-36. A portion of the old Mark Twain Memorial Bridge remains is preserved at Cardiff Hill Overlook Park in Hannibal.

Starved Rock Lock and Dam

(John A. Weeks III, Satellite)

20150807,08 3873
The Starved Rock Lock and Dam has a Visitor's Center that is open 9-5. But you need some guts to continue down the road past a fence to find it. I had parked in a parking lot upstream of the scary looking fence. But when I saw people getting on a Starved Rock Trolley, I decided to go back down the road to check it out. You can tell that the three state parks near LaSalle creates a tourist industry for LaSalle. And this is probably why this lock and dam is taxpayer friendly. None of the other lock and dams on the Illinois river that I have visited allow pictures to be taken. And some don't even allow visitors!

On the right is the plaque for the propeller laying on the ground in the above photo. I was surprised that the towboat was steam/electric rather than diesel.

The Visitor's Center had a second story balcony so that you did not have to try to take pictures through a chain link fence. And you can see over the lock to see the dam. The picture below was taken on Aug. 8, 2015. Note that only one gate was open. The attendant in the visitor center did not know how far the gate was open. Judging from the angle of the gate, it is not open very far. Note that these Tainter gates are counterbalanced. The only time I have seen that before was the control gates for the Marseilles North Mill Headrace.

I stayed overnight in Peru so that I could take more pictures in the Peru-LaSalle-Ottawa area. When I again stopped by the dam the next day, it had three gates open.

USACE posted five photos with the comment:

Have you ever wondered how the water is kept out of the lock chamber in a dewatered lock? It takes a lot more than just closing the gates on the upper and lower ends! Bulkheads are put in place when the chamber is full. They are stacked on top of each other and secured by divers. Once that is complete at both ends of the chamber, then the chamber can be pumped down. The photos below depict that process at Starved Rock Lock and Dam during the current Illinois Waterway Consolidated Lock Closures. #ILWW2020Closures
Jay Davis Not only do they install bulkheads above and below the lock chamber, you also set bulkheads above and below each filling and emptying valve for the lock chamber. 
Jon James Bet yal see some big fish in those chambers when dewatered, how do yal get the fish out? Lol

Dennis DeBruler commented on Bill Strealy's comment ("Do the bulkheads support the gates?") on Ben's post
No. They create a temporary gate so that the movable gate can be worked on in a (relatively) dry lock. Here is a photo from the Peoria Lock work that illustrates this.
Bill Strealy Dennis DeBruler OK Dennis, thanks for the reply and that sure makes a lot of sense. I have never been around a lock.
Dennis DeBruler In fact, I just discovered that the work for Starved Rock is to replace both the upper and lower miter gates. That is probably why they have a ringer crane at this lock. I presume that the lower gates are rather heavy.

A photo dump of the photos I took on Aug 8, 2015 when I caught a tow going downbound through the lock. I used the new version of Google blog writing software since they had fixed their performance problem for photo insertion. This insertion was 63 photos.



























My intention when I took these photos of the tow entering the lock was to add the timestamp for each. But Windows Explorer doesn't include the seconds. And since I don't know of a quick way to get the timestamp with a resolution of seconds, I'm skipping the timestamps.

























This is when I learned I have a hard time taking a vertical photo when leaning over a handrail.









The next day, on my way back home, I stopped by the lock during business hours and got photos inside the visitor center. This photo insertion test was with 13 photos. All three of these tests passed. The bug of inserting photos at the end of the post instead of at the cursor did not appear.
