Steve, Around 1909 the CB&Q began making the concrete pieces at Hannibal.
Because of the big cement plant located about 3 miles south of Hannibal at
Ilasco, there were many men familiar with concrete procedures and they hired
several to begin this operation. I have some nice pictures of the group
posing around their forms and finished products. There are pilings, large
culverts, slabs, etc. Early 1920s pictures indicate the operation was still
going on, but by the 30s it seems to have tapered off. One of the piers is
still lying on the bank of the river and scratched in the end are the
letters HANN and the date. When they tore out the old trestle at Keokuk
that was located about 100 yards south of the old roundhouse over Blood
Creek, these long concrete pilings were all marked with Hannibal IDs and
dates around 1918 or so. Archie

Most of the bridges on the C&I are concrete many have recently been
replaced. A neat concrete pile trestle use to be still in place on the old
H&St J west of Brookfield on the old Main The rails were gone but the
bridge remained.
These articles tell how and where the piles and slabs were poured and loaded
for movement to the job locations

Subject: [CBQ] Concrete bridges
List,
An acquaintance manufactures a line of concrete bridges from the 80's to
present and said,
"I'm VERY interested in acquiring photos/drawings of the Q-style
concrete bridges for product development, but have almost nothing compiled
about them. Those would easily go back to the 40s and 50s, and I'm looking
forward to adding them to my line in the future."
Does anyone have or can point me in the direction of the requested
material?
