Electronic tolling makes this problem go away.
The other bridges are pretty full and this one is waaaaaay beyond it's capacity. This is important for all of Ohio because of the logistics industry. Bottlenecks can really make or break a place in terms of setting up shop.
You erroneously assume that everyone will buy an EZ Pass. Some local residents who are daily commuters back and forth across the bridge may do so for convenience--nevermind that the toll is a greater inconvenience--but others will protest the idea, and less frequent travelers may not be able to justify the fees. A lot of people will instead opt to take I-275 over the river and back, resulting in longer commutes and traffic congestion elsewhere.
I suspect that there are other, as of yet unacknowledged methods of allocating funding for this project. I've noticed for instance that Ohio is moving ahead with widening I-71 to three lanes up in Morrow and Delaware counties. May I ask why? While the project once completed will certainly make for a smoother drive for those who travel back and forth between Columbus and the Cleveland-Akron area with some regularity (myself included), it shouldn't be nearly as high a priority as replacing an aging key gateway bridge that connects the heart of a metropolitan region and so much more. Even the central interchange project here in Columbus could be put on hold for a while longer to deal with the bridge.
