ThawWatch

Know when frost laws go on, before you load.

ThawWatch texts and emails you when seasonal weight restrictions go on or come off for the Michigan counties and state highways you follow.

For haulers, septic pumpers, well drillers, log trucks and anyone else who runs heavy on local roads in spring.

Frost laws don’t go on all at once

Michigan’s seasonal weight restrictions aren’t one date for the whole state. Each of the 83 county road agencies puts its own on and takes them off as the ground thaws and firms up, and MDOT does the same for the state highways.

The notices go up on each agency’s own website or phone line, often at short notice. Run overweight on a restricted road and you can be fined. Too often a driver finds out after the load is on, or from the officer.

What ThawWatch does

  • A text to the cab

    When restrictions go on or come off for a county or road you follow, you get a text, with the time the agency gave.

  • County roads and state highways in one feed

    All 83 county road agencies and MDOT’s state highways, so nobody has to check 84 websites every morning.

  • Road-by-road lists

    Where an agency posts which roads are restricted and which are all-season routes, ThawWatch lists them road by road.

  • Email for the office

    The same alerts by email, so dispatch knows as soon as the drivers do. Michigan first, with more states coming.

ThawWatch reads the agencies’ public notices; it doesn’t replace them. Every status shows when the agency last updated it. Always confirm with the road agency before you travel.
