Telegraph photo by DEAN SHALHOUP Full tables and busy servers are gradually becoming more commonplace since city officials launched the expanded outdoor dining initiative two weeks ago. Most of these diners are customers of Casa Vieja Mexican Grill at 96 Main St.

NASHUA – The Jersey-style barriers for outdoor dining on Main Street will be preliminarily placed on Monday, city officials said.

The barriers will initially be placed next to the curbs to allow Positive Street Art and Beyond Walls an opportunity to paint them. As portions of the barriers are finished, they will be put in their permanent locations by the Department of Public Works. Work will start on the South end of Main Street and move North. All barriers will be in their permanent locations by April 15.
