The Interstate 74 proposal along Kentucky's AA Highway died much the same death as Ohio's proposal for the same highway along US 23 and Ohio Route 32, and like the Interstate 73 proposal through Ohio. The AA Highway handles traffic well, although it needs upgrades and modifications. It is a major east-west route that connects the Cincinnati market to points east, and can save travelers two hours that they would otherwise need to take Interstates 75-64, US 52, or Ohio Route 32/US 23 as an alternative.
There is a proposal to widen the AA Highway to four-lanes eastward to Maysville. The current four-lane alignment ends at the Campbell County border, and the cross-section for that four-lane segment is two 12' through lanes and a 12' right shoulder, with a mountable median. Access is limited and there is one interchange at US 27. There are driveways that access the highway, but the access is controlled. The four-lane extension east would most likely take the form of other rural Kentucky four-lane highways, with two 12' through lanes, a 12' right shoulder and a 6' left shoulder with a 36' depressed, grassy median. I hope that access is further tighened so that all driveways are eliminated.
The state is also currently purchasing right-of-way for an outer bypass of Maysville that will be a limited-access, four-lane freeway. It will replace a five-lane roadway with curbs, although it doesn't experience much congestion.
