Section 251. Payment of expense of acquisition

One-half of the expense
  incurred in the condemnation and acquirement of said toll  bridge  shall
  be  paid  by  the department of taxation and finance upon the warrant of
  the comptroller out of any specific appropriations made to carry on  the
  provisions  of this article, but no such payment shall be made until the
  county or counties in which said  toll  bridge  is  situate  shall  have
  complied  with  all  the  provisions  hereof.  One-half  of the expenses
  thereof shall be a charge, in the first instance,  upon  the  county  or
  counties  in  which  said  toll bridge is situate, and the same shall be
  paid by the county treasurer upon the requisition  of  the  comptroller,
  but  the amount so paid shall be apportioned by the board of supervisors
  so that thirty-five per centum of such cost shall be  a  general  county
  charge  and  fifteen per centum shall be a charge upon the town or towns
  or city or cities in which said toll bridge is wholly or partly located.
  In case a toll bridge is located in two counties the fifty per centum of
  the expense to be borne by the counties  shall  be  apportioned  between
  them on the basis of their assessed valuation and the fifteen per centum
  shall  be apportioned by the board of supervisors upon the town or towns
  or city or cities in the same manner. The  board  of  supervisors  of  a
  county,  the  town  board  of a town or the common council of a city may
  determine that the portion of the expense  chargeable  to  such  county,
  town,  or  city,  as  the  case  may be, shall be raised by taxation and
  levied and collected as other municipal taxes, or the money therefor may
  be raised, in whole or in part, pursuant to the local finance law.
