The boards of supervisors of Erie and
  Niagara counties, or either of them, may each  agree  and  undertake  to
  provide  and  make  available,  and to appropriate annually such sums as
  they may deem proper to aid the Niagara frontier  bridge  commission  in
  the  maintenance  of  the  two  bridges erected by it across the Niagara
  river to Grand Island, and for the  purpose  of  thereby  improving  and
  extending  the  highway  system of the state and of the counties of Erie
  and Niagara. Such annual appropriation hereby authorized to be  made  by
  the  board of supervisors of Erie county shall not exceed the sum of two
  hundred thousand dollars for any one year, and such annual appropriation
  hereby authorized to be made by the  board  of  supervisors  of  Niagara
  county  shall  not  exceed the sum of fifty thousand dollars for any one
  year. Each board of supervisors may  by  resolution  direct  the  county
  treasurer  to  pay the amount of such appropriations to the treasurer of
  the Niagara frontier bridge commission. Each board  of  supervisors  may
  cause  such  moneys to be raised by taxation and levied and collected as
  other taxes in such county.
