Laying sewer pipes along Lawrence Ave, 1918, Chicago
The comments indicate the scaffolding in the middle is to allow workers to construct a brick arch for the top of the pipe.
Michael Pazanin Looks like there lined with Brick , at that time there where more bricklayers then all the other trades tougher!!!
No wonder I keep finding brick plants in various towns. Illinois is lucky that it sits on top of sedimentary rock that has a lot of outcroppings of coal, sand and clay.
