Section 6-608. When village may relinquish care of bridges

Any village
  which has the supervision, control, care and maintenance of  any  bridge
  or  bridges  wholly  within its boundaries, or which has entered into an
  agreement with a town as provided in sections 6-604 and  6-606  of  this
  chapter, may with the consent of the town board of the town within which
  any  such  bridge  is  situated,  by resolution of the board of trustees
  subject to a permissive referendum as defined in this chapter, terminate
  the right of such village to supervise, control, care for  and  maintain
  such  bridge  or  bridges, or cancel any such agreements made by it with
  such superintendants of highways, and  thereafter  every  public  bridge
  within  the  boundaries  of said village shall be under the supervision,
  control, care of and maintenance of the superintendants of  highways  of
  the  town  as  provided  in  section 6-602 of this chapter. Such action,
  however, shall in no way cancel or interfere with the  validity  of  any
  obligation  or  indebtedness  of  the village incurred during the period
  that  the  village  exercised  the  supervision,   control,   care   and
  maintenance  of  such  bridge or bridges, or during the period that said
  agreement was operative.
