There's no bridge category so I'll post it here. Has anyone ever heard of a false arch bridge? There's one in Minot, ND. The arches are not structural. The bridge is a cantilevered deck open spandrel arch. The arches above the substructure are ornamental only. The bridge was built this way because the town wanted a Marsh rainbow arch bridge but didn't want to pay the Marsh company patent fees. So they built it this way. It's a very unique bridge. Are there any other false arch bridges in the US and A?

I suspect the arches on the Troop-Howell bridge in Rochester, NY are just for looks. The modern bridge replaced a simple beam bridge that is otherwise identical to it.
A few of the Merritt Parkway's famous bridges are like that. The underside is flat, the "arch" is just a shape formed by panels on the sides.

Beams are way too shallow for the arches to not be structural on that bridge.
Maybe this deserves its own topic, but what about false cable-stayed bridges?

Isn't these two overpasses in Cincinnati false cable-stayed bridges?

An example of the Merritt Parkway bridges I mentioned before:

It's made to look like an arch when viewed while approaching, but the curved form is just non-structural concrete plates. One of them on this bridge was missing for several years.
