Section 83. Construction or improvement, partly at county expense

If the
  estimated cost of a project  in  any  county  shall  exceed  the  amount
  available  in  such county for such work to be provided by the state and
  federal  government,  the  board  of  supervisors  of  the  county,   by
  resolution,  act  or  ordinance, may approve of such project within such
  estimate and may provide that the county shall pay the  amount  of  such
  excess. If the commissioner of transportation thereafter shall determine
  to  proceed with the project, the board of supervisors shall appropriate
  sufficient moneys to pay the amount of such excess. Moneys to meet  such
  appropriation  may be provided from moneys raised by tax, from available
  moneys in the county road fund, from other available moneys or  pursuant
  to  the  local  finance law. Moneys so appropriated shall be paid out by
  the county treasurer  on  the  written  order  of  the  commissioner  of
  transportation.    The  form  of any resolution, act or ordinance making
  such  an  appropriation,  shall  be  approved  by  the  commissioner  of
  transportation,  and  immediately upon the adoption thereof the clerk of
  the board of supervisors shall transmit a  certified  copy  to  him.  No
  resolution,  act  or  ordinance  thereafter  adopted by such board shall
  amend or repeal any prior resolution, act or ordinance adopted  pursuant
  to  this  section,  either  directly  or indirectly, excepting under the
  advice and with the consent of the commissioner of transportation.
