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.
22 current reports along the route. The 8 most serious are listed below. Always check with the responsible state DOT before setting off.

Winter reporting is off for the season. The state DOT feeds this page reads for Wisconsin run from October 15 to April 15; outside that window they change only as needed. Our own forecast below runs year-round.
Reports for Wisconsin come from each state's DOT, entered by maintenance staff and describing what is on the pavement, not the forecast; the state pages carry each DOT's terms and notices. Always check with the responsible state DOT before setting off.
