Saying it will ease congestion on Elm Street, parking officials are seeking to re-designate a loading zone just off the main drag downtown as 24 hours. The loading zone on the west side of South Avenue, just below Elm, currently is in effect from 9 a.m. to 3 p.m., according to Parking Manager Stacy Miltenberg. But “people don’t read the signs that say ‘loading zone’ and they’re constantly using it as a parking spot,” she told members of the Parking Commission during their regular meeting, held Wednesday at Town Hall and via videoconference. “So it’s a recommendation that we make it a loading zone 24/7, technically, because we want to mark the street,” she continued. “If you mark the street, then it can’t go back to a regular parking spot at 3 o’clock.
