Ed. note: Post updated with fact it was steam, not smoke from a fire.
The Cambridge Fire Department reports what appeared to be smoke was actually just steam from a manhole at Land Boulevard and the Monsignor O'Brien Highway shortly after 7 p.m.
Still, police shut the roads down by the Museum of Science as a precaution until firefighters could confirm that.
