Polling station question

[Kushahontas]

How far apart are polling stations from each other in the US? How far do you generally need to go?

my usual precinct is just a 10 minute drive down the street. this year i'm early voting at a polling place on my college campus. in the past, it was kind of inconvenient because the old polling place at an elementary school was only a half mile away but it was across a freeway so it took around 10 minutes to get to a turnaround to go the other way. I live in a suburban part of a large city.
