Western Avenue Overpass

Speaking of Riverside I actually wish it was still open as I am not only a bridge enthusiast but an Amusement Park enthusiast... That park appearantly had some fantastic rides, and classic wooden roller coasters (A type disappearing almost as fast as Truss Bridges)... Regardless this was definately an ugly bridge and not really historic at all.

Here's a bridge demolition that has widespread community support. This overpass has been considered somewhat of an eyesore and community divider, after nearby Riverview Amusement Park closed in 1967. Now it has deteriorated seriously, so it's also an example of the short life span of some modern bridge designs, in this case prestressed concrete box girder. It's a big bridge that carried heavy traffic, so the traffic disruption of the demolition project will be considerable. It will be replaced by a 5-way surface intersection controlled by traffic signals, along with room for wider sidewalks.
