Miles to the nearest Interstate.
Straight-line miles from the county's population-weighted centre to the nearest Interstate centreline. This is not driving distance and does not assert access to an interchange; local terrain, water and the road network can make the trip much longer. Interstate geometry and major route labels are drawn when a state is open. Alaska and Hawaii have no Interstate route in this source, so they are left without a value rather than assigned a fabricated zero.
District of Columbia has the lowest published highways & freeways in this comparison, at 0.4 mi. The next states shown are Massachusetts (2.6 mi) and New York (2.7 mi).
The table orders 49 states by miles to the nearest interstate. It describes one published measure, not an overall judgment about where to live.
Use the result as a starting point, then compare the underlying source, dates, and local county figures before making a decision.

Free to use. The chart names its source and links back, so it stays honest wherever it ends up.
