2020 Main frost law restrictions.
Each spring, Maine DOT evaluates potential damage to state highways and determines whether weight restrictions should be imposed to prevent damage due to freeze/thaw action. Many municipalities undertake similar evaluations and restrictions on local road systems.
This means that a road that can carry a 15-ton load in the summer or winter may only be able to carry a 5-ton load as it thaws. A posted state road's maximum weight limit is 23,000 pounds. The posting is temporary and is designed to protect a road while it is vulnerable.
