  legislative body of any city or village with respect to highways  (which
  term  for  the purposes of this section shall include private roads open
  to public motor vehicle traffic) in such city  or  village,  other  than
  state  highways  maintained  by  the  state  on  which the department of
  transportation shall have established higher or lower speed limits  than
  the  statutory  fifty-five  miles  per  hour  speed limit as provided in
  section sixteen hundred twenty of this title, or on which the department
  of transportation shall have designated that such city or village  shall
  not  establish  any  maximum  speed limit as provided in section sixteen
  hundred twenty-four of this title, subject to the limitations imposed by
  section sixteen hundred eighty-four of this  title  may  by  local  law,
  ordinance,  order,  rule or regulation establish maximum speed limits at
  which  vehicles  may  proceed  within  such  city  or  village,   within
  designated  areas  of  such  city  or  village or on or along designated
  highways within such city or village higher or lower than the fifty-five
  miles per hour maximum statutory limit. No such speed  limit  applicable
  throughout  such city or village or within designated areas of such city
  or village shall be established at less than twenty-five miles per hour;
  except that in the city of Long Beach, in the county  of  Nassau,  speed
