About two miles further downstream is the Business 80 Bridge. It's an eight-span steel plate girder bridge on oddly-shaped two column bents. The tops of the columns have pedestals that support the girders. The bridge was built in 1954 and renovated (and seismically retrofitted) in 1996.
This is a very busy bridge and expressway, and it's usually stop and go during rush hour. Its also quite noisy and you can hear the traffic from a mile away. I think steel plate girders must be noisier than concrete box girders.
