Joe, I would tend to disagree with you…not about the number of toll booths required, but about the very existence of them anywhere on a highway, whether at ramps or at the state line. They can be a colossal nuisance. The last time I traveled to New England, we decided to pull all-nighters both ways and try to minimize the traffic impact. No dice. On our return home, we were stuck in a two-hour backup at the end of the New Jersey Turnpike as we approached Delaware. Those wonderful E-Z Pass lanes (which we wouldn’t have been eligible for anyway) are meaningless if you can’t get past the long two-lane highway to the last quarter-mile to half-mile before the booth, where the lanes expand.
Toll booths are choke points, especially in highly traveled areas.
