This bridge is one of the younger examples of a deck truss
bascule bridge in Chicago. Unlike a number of bascule bridges in Chicago, the
truss is a true deck truss with the entire truss below the deck, and no part of
the truss visible from on top of the deck. The bridge appears to retain good
historic integrity with no major alterations noted aside from the replacement of original railings in 2012. Prior to 2012, the sidewalk was in poor
condition but the overall bridge appears to have been in decent shape.
A plaque on the bascule bridge relates a variety of information including that this is the fourth bridge at this location, however the plaque fails to list the contractors for the construction of the bridge. There is also a separate plaque for the approach viaduct system south of the bridge located a short distance south of the bascule bridge on a railing. This viaduct system of simple stringer spans is not included as part of the bridge proper and so the lengths of these viaducts are not included in the technical facts table on this bridge page. The 1955 Annual Report of the Public Works Department listed the contractors for the bridge. The Overland Construction Company built the superstructure with a bid of $1,657,329. The Fries Walters Company won the electrical work contract with a bid of $261,691. Walsh Construction Company built the bridge tender house and enclosures with a bid of $139,982. Pielet Scrap Iron and Meal Company demolished the previous bridge for $127,405. Michael J. McDermott Company built the northern approach viaduct system with a bid of $103,986.75.
During 2012, this bascule bridge was rehabilitated for about $5 million. Work included replacement of floorbeams, deck stringers, and lateral bracing. Some repairs to the trusses were undertaken as well, but this was not a major reconstruction of the trusses. The somewhat utilitarian railings that were present on the bridge (yet were in fact the original railings) were replaced with new railings with decorative flower designs that are a nod to earlier railing designs used in Chicago.
