This attractive bridge was the design of noted engineering firm Modjeski and Masters. The bridge consists of a single suspended span over the river. Only the center span is suspended on this bridge, and so straight backstays are present on this bridge instead of suspended side spans. This is a less common arrangement for a suspension bridge. The bridge appears to be in good physical condition and retains good historic integrity. While not a particularly old example of its type, suspension bridges are sufficiently rare that this bridge nevertheless should be considered a significant historic bridge.

Discussion of Bridge
In 1944 an act of the U.S. Congress authorized the
organization of the City of Clinton Bridge Commission to supervise the
planning, financing and construction of a new bridge across the
Mississippi. The first meeting of the seven-man board was held on April
5, 1945 (Clinton Herald, June 29, 1956:20). Traffic counts and surveys
were conducted in 1945, 1946, and 1953 to gather information in support
of the financing and potential location of the new bridge (Clinton
Herald, June 29, 1956:29). The ISHC contracted Modjeski and Masters of
Mechanicsburg, Pennsylavnia to design the bridge. Plans were drawn up in
1951 and finalized in January 1954. Work on the bridge began on
September 21, 1954. Allied Structural Steel Companies of Clinton
provided the steel for the bridge. The bridge was completed on June 30,
1956. The total cost of the bridge was $6.8 million (City of Clinton
Bridge Commission 1956:2). In 1976, repairs were made to the west
abutment and four piers on the west side of the bridge.
