After this and the identified Wyoming sites the largest gap will be 159 miles. However, there's a significant diversion forced in Macedonia, OH and West Middlesex, PA (due later this year) could help avoid a stop there.
West Middlesex, PA (especially) and Bellefonte, PA are on Tesla's site for later this year.
* Just within range. US-322 is just outside that range.
** _But_ a very significant diversion. West Middlesex, PA will be very helpful to allow some people to avoid it.
