Temporary weight restrictions have gone into effect beginning March 8, 2021 on certain County roads. As frozen ground thaws, base gravel in the roadbed becomes saturated, causing surface break up and premature failure. In these conditions, fully loaded vehicles can cause severe road damage.

The load limits for all restrictions are 7 tons for single axles, 14 tons for tandem axles, or 350 pounds per inch width of tire.

Temporary restrictions will be in place for the following roads in Lewis & Clark County:
