Description

This bridge should be considered historically significant as one of the oldest unaltered examples of a concrete curved t-beam overpass on I-90. The bridge predates the formation of the Interstate Highway System. The bridge retains original concrete balustrade railings, something very few of these overpass bridges retain.

Argonne Road Bridge

I was hoping to find the underpass clearance for an overheight truck load, but judging by the pictures, it looks like a safe bet.

Thanks.
