Beginning Tuesday at 6 p.m., the city’s Traffic Division will begin painting the brick-stamped crosswalks in the downtown area. They will begin at the intersection of Central Avenue and Chapel Street, working northward. They will continue to work nights until all crosswalks are completed, weather permitting. Traffic on Central Avenue will be restricted to one lane at a time during the project, which is expected to take four to five evenings to complete, weather permitting. Flagmen will be present, and motorists are urged to use caution in the work area.
