DALTON, Mass. — The Select Board is looking to open Town Hall for business by the beginning of next month, but will continue to hold its meetings remotely for the time being. With a variety of new safety features in places and consistently reassuring numbers in Dalton throughout recent weeks, town is staged to reopen access to key town offices to the public by the first week of April. "We're in a much better situation than we were a year ago," said Jayne Smith, the town's health agent, who detailed signage, workplace barriers and other provisions put in place in the building.
