2006 New York Code - Establishment Of Temporary Detours When State Highways Are Being Maintained Or Repaired.

 
    §  42-a.  Establishment  of  temporary detours when state highways are
  being maintained or repaired. Notwithstanding the provisions of  section
  one  hundred four of this chapter, whenever in the maintenance or repair
  of a state highway, it is determined by  the  commissioner  that  it  is
  necessary  to  provide  for  a  temporary  detour  over alternate roads,
  streets, highways or routes, the commissioner shall have the  power  and
  authority  to  establish  such  temporary  detour  over alternate roads,
  streets, highways or routes as he deems necessary  and  proper  for  the
  protection  of  the  traveling  public  with  the posting of conspicuous
  signs, or use of flagmen, or  a  combination  thereof,  indicating  such
  temporary  detour.  Such  temporary  detour shall be adequate to prevent
  unreasonable delay in the movement of traffic on said state highway.  As
  used  herein  "temporary  detour"  shall  be  a detour of an anticipated
  duration not to exceed two weeks.
