There will be a pair of weekend closures in the emergency room at Fishermen's Memorial in Lunenburg. South Shore Health is advising area residents the ER will close Friday evening at 5:00pm and won't re-open until Saturday morning at 7:30am. It will also close overnight Saturday during those same times. Staff shortages are the reason behind the temporary shut down. Those needing emergency services should go to the regional hospital in Bridgewater or dial 9-1-1.
