Road weight limits being posted as weather gets warmer

February 22, 2018

CONCORD, N.H. (AP) — The New Hampshire Department of Transportation is posting road weight limits for vehicles on roads as the weather gets warmer.

Warmer weather means sections of roads will be vulnerable to pavement breaking up as the frost leaves the underlying road base. Road postings are determined annually by local Transportation Department engineers, who carefully review each roadway in their areas before posting a road limit to ensure protection of the roads.

The maximum allowable vehicular weight posted sections of state highways is 30,000 pounds gross weight, or the cumulative width in inches of all tires contacting the road surface multiplied by 300, whichever is less.

Under state law, trucks carrying home heating oil, processed milk products, maple sap, and septic pumper trucks are exempted from seasonal bans with the department’s approval.
