. This light-blue cantilever bridge carries two lanes of traffic and a narrow sidewalk.

In 2000, the Ohio Department of Transportation released a report recommended the replacement of the then 78 year old span. The bridge was retrofitted in the 1970s with strengthening beams and plates.
Later inspection of the bridge revealed that these plates had been welded to the bridge using techniques that violated the bridge welding codes and reduced the fatigue strength of primary load members. As a result of these findings, ODOT added reinforcements to some vertical members to improve structural redundancy.

The bridge will still be forced to close when temperatures approach -5 degrees Fahrenheit due to the brittle nature of the steel used. Continuous monitoring is routine during temperatures below freezing to check for any cracking in the substructure of the span. In addition, in May 2008, ODOT placed a width restriction on the bridge, banning all vehicles that are wider than 7 ft. 6 in. Emergency vehicles, non-commercial vehicles and non-profit busses (such as school bus

One of the replacements considered was a three-lane single-tower cable suspension bridge. The final design was chosen in January 2003, however, the high costs of constructing the bridge became apparent when costs for the new bridge came in at $110 million, well over the original estimated cost. The sharp rise was attributed to the dramatic increase in construction costs partially blamed on Hurricane Katrina
