Section 129. Maintenance and apportionment of cost

Notwithstanding any
  other provisions of law, the maintenance of  roads  improved  under  the
  provisions  of  this  article  shall be the responsibility of the county
  under  the  jurisdiction  of  the  county  superintendent  of  highways.
  Notwithstanding   any   other  provisions  of  law,  the  cost  of  such
  maintenance may be paid by the county from any funds in such county that
  are available and that may be legally used for highway or road  purposes
  or  from county funds raised, provided and appropriated therefor, in the
  same manner as it raises,  provides  and  appropriates  moneys  for  the
  construction  of  a road or highway under the provisions of sections one
  hundred and ninety-four and one hundred and ninety-five of this chapter;
  or, notwithstanding any  other  provision  of  law,  the  cost  of  such
  maintenance may be paid from the county road fund.
    In  either  case  the  county  may  apportion such cost of maintenance
  between it and the local municipalities in which such road or highway is
  located, and the amounts to be so borne by  the  county  and  the  local
  municipalities,  respectively,  may  be  raised and provided in the same
  manner as money is raised and provided under sections  one  hundred  and
  ninety-four  and  one  hundred  and  ninety-five of this chapter for the
  construction or improvement of a road or highway where the cost  thereof
  is  apportioned between the county and a town or towns; or, such cost of
  maintenance, as apportioned,  may  be  paid  by  the  county  and  local
  municipalities,  respectively,  from  any funds in such county and local
  municipalities, respectively, that are available and that may be legally
  used for highway, road or street purposes.
    The term "improved roads" as used in this section shall be  deemed  to
  refer  to  and  mean  highways  or  roads with a pavement of substantial
  character sufficient to afford a hard driving surface at all seasons  of
  the year and which can be efficiently maintained at all times.
