I went ahead and looked, and the people who did this are dead wrong about Florida, and there are not three Ohio turnpikes! The three "turnpikes" are various sections of the road between different geographical points according to your own source.
And, as far as I can tell from my American Map Corporation atlas, there is one friggin' Maine turnpike with one named spur (and a couple unnamed short ones)! And I'll wager my road atlas is far more accurate than your source.
Since you apparently can't, or don't, read links, the source is on the top of the page. The US Department of Transportation.
Perhaps you might check out the length of the various turnpikes to resolve your concerns.
