4500 South Bridge

In 2008, I made a gallery of the construction of the 4500 South bridge. The construction project included numerous innovations. The bridge is crawling up the alluvial fan of Mount Olympus and climbs a steep hill; so that had to engineer a bridge for a steep climb.

The notable design improvement in this construction is that the built the bridge to the side of the road, then closed the freeway for a single day to drop the bridge in place.

Big Stock Photo approved one of the images I took of the bridge.
