A secondary road running parallel to a highway, providing access to adjacent worksites, lease roads, or staging areas. Subcontractors often use frontage roads for heavy equipment moves or crew dispatch without entering main traffic. Confirm load restrictions and municipal permits before routing oversized hauls.
