City of Cambridge offices, libraries and senior centers close Jan. 16 for the Martin Luther King Jr. Day holiday, according to a Thursday email from City Hall. Curbside collection service will be suspended and parking meters and other municipal parking payments will not be required.

Curbside collection of recycling, compost and trash will be one day behind schedule for the rest of that week. (Street cleaning and yard waste pickup are suspended for the winter season and resumes in April.) Cambridge Cemetery at 76 Coolidge Ave. will have gates open from 7 a.m. to 5 p.m. on Martin Luther King Jr. Day, but the Cemetery Administrative Office will be closed.

Curbside pickup of undecorated Christmas trees runs through Jan. 13 on curbside collection days. Decorations and stands must be removed and trees should not be in a plastic bag. Residents can also bring bare trees to the Recycling Center.
