Still not enough to make me like bison. Maybe if it were an historic swing truss.

Oddly, there is a already a push to preserve the bridge for pedestrian and "bison use" as a national park.

Illinois and Iowa are planning to replace the 1960s I-80 Mississippi River bridge since it's high maintenance and already functionally obsolete. The question is will the replacement bridge be an utilitarian UCEB or a signature span like a tied arch?

This bridge has recently had its inspection report blocked from public view by both the Iowa and Illinois DOT's citing security concerns, I heard something about hairline cracks and mentions of the bridge collapse in Minnesota so I'd avoid this bridge for awhile, especially since lane closures has traffic backed up in both directions frequently.

Avoid The I74 Bridge if you're traveling through anytime near rush hour.

Passing through the Quad Cities on I-80? There are at least two more interesting ways to cross the Mississippi than this ugly bridge clogged with big trucks. Cross the doomed and historic I-74 suspension bridge instead, or the modern and interesting bowstring arch Sergeant John F. Baker, Jr. Bridge on I-280, which is often faster than I-80. Many other great choices if you're willing to get off the Interstates, such as my favorite, the Arsenal Bridge.
