The 300 and 400 blocks of Hillside Avenue between Route 23/Columbus Street east to Everette Road in Ottawa will be closed to traffic beginning at 7 a.m. Tuesday. Weather permitting, contractors are scheduled to begin sewer repair. They expect to complete the work by the end of the day. If not finished, the street will reopen to traffic that evening and the street will close again Wednesday until the repair is made. Drivers from Gracefield Subdivision who travel on Oaklawn Avenue to Everette Road are advised they will not be able to use that section of Hillside Avenue to reach Route 23/Columbus Street and must take an alternate route.
