Be cautious if you plan to go to Canton-Potsdam Hospital on Monday.

The main driveway entrance from Cottage Street to the hospital’s emergency department will be closed for repairs for 24 hours beginning at 6 a.m. Monday.   The entrance will reopen at 6 a.m. Tuesday.   Ambulances and other first responders have been asked to use the Grove or Leroy Street entrances instead. Patients and visitors should use the Grove or Leroy Street entrances or cautiously drive through the small parking lot off Cottage Street near the emergency entrance.   Construction will be where the driveway meets Cottage Street. The emergency and main entrances are still open.   Crews will repair the blacktop where it was damaged because of a water main break a few months ago.
