A number of Chicago bridges have most of the trusses below the deck yet part of those trusses remain above the deck as in the State Street Bridge meaning the bridge has some characteristics of a deck truss as well as a pony truss. The Adams Street Bridge is however one of the bridges in which the trusses are completely below the deck, making it a true deck truss. This configuration allows the trusses to be more visible to people rather than partially obscured by the deck of the bridge. The arch shape under the bridge is more defined as well.
