View looking southwest at the partially completed, northernmost section of McCormick Blvd. in Evanston, Illinois, on August 17, 1925. The road in the foreground is Green Bay Road (known at the time as Rail Road Ave.). The MWRD completed construction of McCormick Blvd. (originally McCormick Road) in 1926.
Historical photo of the week: A Koehring paver and crew at work on a section of McCormick Blvd on July 15, 1925. The MWRD completed construction of McCormick Blvd. (originally McCormick Road) in 1926. It was named in honor of Colonel Robert Rutherford McCormick, who was the Sanitary District's President before the construction of the North Shore Channel (1907-1910).
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.
A posting by Chuck Edmonson concerning the first "seedling" mile built for the Lincoln Highway in 1914 near IL-38 near Malta, IL contains some pictures of the concrete mixer technology of the day.

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.

Concrete for building big intercepting sewers was also mixed on site.
