Or the truckers will find a different route. In northern Ohio truckers will jump off of the Ohio turnpike, especially right after toll increases. Route 2, while only 2 lanes each way and poorly maintained, gets a ton of alternative turnpike traffic. Also trucks jump off of the turnpike and grab the 480 southern bypass to CLE and deal with arguably the worst traffic in the city just to shave off some $s.
But things are different when you are dealing with a major geographical component like a large river crossing. The bridges to span these things are not simple engineering jobs so the costs are significant and options limited for secondary crossings limited. There are also challenges when dealing with two different states and the unique philosophies about how to pay for these things. I would think Northern Kentucky needs this more than Southwest Ohio but then again the metro airport is located in Northern KY. Either way a new bridge is needed and everyone needs to chip in to make it happen.
