This massive arch bridge crosses Piasa Creek parallel to US-67 between Godfrey and Delhi.
Ever since it was completed, the bridge has had structural issues. It was built unstably in 1881.
In 1904 and 1911, rehabilitation was done to stabilize the bridge. By 1918, the railroad decided to encase the bridge in concrete to prevent further damage to the structure.
General plans of the bridge
The rehabilitation worked, and has continued to preserve the bridge for generations. It is not currently know why the arches were not structurally sound.
Despite this, the bridge contains five identical arches. These arches are considerably higher than other structures.
The author has ranked this bridge as moderately significant, due to the historic age and early alterations.
The photo above is an overview. More photos of this bridge are hoped for the future.
