More Ghost Bridge Piers: Lemont, IL over the Des Plaines River
Looking at this bridge in Lemont, IL, you’ll see ghost bridge piers in front of it, just to its immediate west. They're quite easily visible from the Lemont Road Bridge.
So why do these piers exist, and what was the bridge they used to carry used for?
From what I’ve been able to tell, they are remnants of a former bridge which once stood here (over the Des Plaines River), before the Sanitary & Ship Canal was built. The Metropolitan Water Reclamation District built the currently standing bridge around 1900. This bridge carries the BNSF Chillicothe Subdivision.

My initial thought was that they were simply bridge piers from an earlier mainline bridge, except that didn't appear to be the case, as the piers have been there since at least 1938.

I've seen only one piece of photographic evidence of this former line, and it's very subtle, but it shows that both bridges were used at the same time at one point, both the mainline bridge which is obviously still in service, and this bridge, which appears to have been used in the construction of the Sanitary and Ship Canal and the channelization of the Des Plaines River.
"It was 1899 when the Chicago Sanitary and Ship Canal was being completed - and this photo was taken of the two bridges that spanned the waterway. On the left is the Stephen Street/Lemont Road bridge, which was used for vehicle traffic - mostly horse and buggy at the time. The bridge was removed in the early 1980s." (Lemont Patch)

If you look very closely at the bridge on the right in the above photo, to its immediate left you'll see a rail line that was either used for construction of the bridge and canal, or quarrying, or most likely both.
LiDAR data shows the right of way continuing adjacent to the mainline north and easterly.

And the final piece of this puzzle is the USGS Historic Topo Map Explorer, which shows the lands where this bridge led to were used for quarrying, like much of Lemont.
