Back to the interesting bridges.

Retro Quad Cities posted two photos with the comment:
(corrected) On August 1st of 1930, the construction began on the New Moline Bridge. It was located at the foot of 16th Street to Arsenal Island with a cost of $275,000. During its construction an ancient piece of pottery was discovered imbedded in the Mississippi river 10 feet below the water line. The pottery resembled a cuspidor. It had the numbers "1813" scratched on it.
Eric Sorensen: There are remnants of the old truss on the Arsenal side of the slough. What’s really interesting is seeing how the water has worn away the limestone abutments over the years. Very cool!
Steve Simpson: Eric Sorensen Limestone is such an amazing rock! It comes from water - calcium precipitated from seawater by shell forming organisms - and it can go back into solution - giving us caves and cool rock features.

This post is noteworthy because it taught me the location of the Moline Plow Works.

Very early pic of the Span to the Island, Rock island with Moline Plow on the right, Deere wagon works beyond that. It's structure looks similar in design to the 3rd span or first government bridge, which was cast by the Baltimore bridge works shipped and built by the Arsenal ordinance dept. I have a post card calling this the government bridge too. Im guessing 1870s to 1880. The motion of the two figures on left tell u something,  whoever took it used a old box camera, pull the cap, count to 10. Long exposure. Probably had better equipment available but didn't possess it.
