Mile markers count from each state's southern line and start again at the next one, which is how most states number their exits as well. They are measured along the same road geometry these pages draw, so they land within a mile or two of the posted markers. A toll road that runs its own continuous numbering is the exception — on the New York Thruway the posts continue from New York City — and there the figure is how far into the state the place is rather than the number on the sign. Distances are measured state by state, never across a gap.
No full closures are reported on I-91 as of Sep 10, 2026 7:48 PM EDT, and no lane closures or roadworks either. Always check with the responsible state DOT before setting off.
