The Cincinnati International airport is actually in Kentuky. No problem, downtown Cincinnati is around 15 minutes driving distance, even getting up north to the 275 is another 15 minutes. Of course, it can triple during rush hour.
The title tells it all. The horse drawn carriages will go over the Roebling Bridge, around Fountain Square, and tour the downtown area.
Several miles of subterranean subway line was constructed in the 30's & 40's, but was never opened.
See my "Subway to Nowhere" local custom tip for more info.
There is a great website for Cincinnati local traffic. Go to the webpage to see live video feeds from main highways and bottlenecks.
I saw many types of vehicles used here. The parking is a Mall parking lot. Address: 300 Forest Fair Dr. Cincinnati, Ohio 45240
