The city recently launched an information hot line that can be accessed around the clock, seven days a week. The Salem Announcements and Information Line will be used to play looped recordings providing announcements on road closures, street sweeping, snow emergencies and plowing, and other timely matters. The number for the information line is 978-745-INFO. The public can follow the information line on Twitter at @745INFO to find out when the recording on the information line has been updated. The system is intended to complement the city’s existing CodeRED reverse-911 notification system, through which residents can sign up to receive city alerts by phone, text, and e-mail.
