Keep in mind that, a lot of the time, there just isn't an answer to some questions. Or, the questions don't make much sense, so people just don't bother answering them.
For example, you're asking about an alternative to the Carolina Bays Parkway. My answer: US-17? That seems pretty obvious (and might be why the question was ignored). The Parkway was built as an alternative to US-17, if I recall correctly. It, therefore, is the alternative. To ask about an alternative to a bypass is a bit odd, I guess. The original route should be the obvious answer, in this case.
The question about 540/US-1 also confuses me. Quick lane drop? Questions that are difficult to discern are likely to be ignored.
Remember: no one here owes anyone anything. We will answer your questions if A) they make sense, B) we can follow what you're asking, and C) we actually know the answer.
A lot of users here (excluding myself and many others, I assume) apparently have autism; we aren't going to hold it against you. We are very much used to how those with autistic tendencies formulate and then ask questions.
