An Alvin Holmes photo shows this bridge still extant in 1942 and is labeled as "Morrison's wrought iron bridge"

A 1936 description of this bridge said it had a "roller coaster floor".

Original bridge across Wabash connecting Pittsburg and Delphi, possible toll bridge at one time. Connecting roads on South approach are long gone and now US 421/Ind 39/Ind 18's bridge is located just Downstream replacing this lost structure.

Melissa found an article confirming that Morrison (Columbia Bridge Works) was the builder.

The third picture shows the abutment from the new bridge. As far as I know, no bridge was constructed on the original alignment once the bridge was removed.

Pittsburg Bridge over Wabash R. on St. Rd. 18
Posted December 3, 2014, by Kevin Howell (kevin [at] ytci [dot] com)

An iron bridge over the Wabash River at Pittsburg in Carroll County was demolished in 1948 - what replaced this bridge? The newer bridge was located just downstream from the original and I believe it too was replaced again in the 1980s or 1990s.

Thanks for any input,

It was demolished in 1948 after the state declared it a flood hazard, per the Delphi Citizen newspaper. It had been abandoned years earlier.
