Section 66. Restrictions on the construction of farm and road bridges

A
  person shall not be entitled to demand a farm bridge across a  canal  or
  feeder  where  the  necessity  of  convenience of such bridge shall have
  arisen from the division or acquisition of property  subsequent  to  the
  location  of  such canal or feeder. A street or road bridge shall not be
  constructed by the  commissioner  of  transportation  over  a  canal  or
  feeder,  except  upon  such streets or roads as were laid out, worked or
  used, previously to the construction of the canal or  feeder,  by  which
  such  street  or road is obstructed; and when bridges are constructed or
  reconstructed upon any such streets or roads,  the  cost  to  the  state
  shall  in  no  case  be  more than is required to preserve in a safe and
  substantial manner the continuity of such streets or roads so as not  to
  unnecessarily  impair  their  usefulness. When a bridge of a more costly
  nature is desired by the local authorities of a city,  town  or  village
  within  whose  corporate  limits a bridge is to be built or rebuilt, the
  commissioner of transportation, on presentation to  him  by  such  local
  authorities  of  plans  and  specifications for such bridge and approval
  thereof by him shall estimate and determine the proportion of the  cost,
  which,  in  order  to preserve the continuity of such streets and roads,
  the  state  ought  equitably  to  pay,  and  file  such   estimate   and
  determination in his office and a duplicate thereof in the office of the
  clerk of such city, town or village. If a private road or public highway
  is  laid  out  by  legal  authority  in such direction as to require the
  erection of a new bridge over a canal for the accommodation of the road,
  such bridge shall be  so  constructed  and  forever  maintained  at  the
  expense of the town, village or city in which it shall be situated.
