We’ve all traveled along an interstate overpass. In most cases they are constructed of bleak concrete, tattooed in graffiti, and built with the sole purpose of getting you across lanes of heavy traffic as quickly as possible. They are a bridge at the bare minimum, but what if they provide something more for the communities they connect? 

In a recent ideas competition, AIA Portland called for creative proposals that would best bridge local neighborhoods divided by Interstate 405. The winning entry, “Five Bridges” by chadbourne + doss, posits that the best way to do this is with inhabitable overpasses.
