Heavy load road postings now under way by DOT

CONCORD - The New Hampshire Department of Transportation customary spring load limits on sections of the State highway system are now under way.

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 NHDOT District 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 (Section 236:3-a), trucks carrying home heating oil, processed milk products, maple sap, and septic pumper trucks are exempted from seasonal bans with the approval of NHDOT District Engineers.
