Public Works is marking new crosswalks on Preston Street at Lee Avenue and on Jackson Avenue at Preston Street. Additionally, Yield signs at both of these intersections will be replaced with Stop signs next week. These changes are being made in an effort to improve pedestrian safety, particularly for a large number of school children who use these routes to walk to and from school. Motorists should be alert to these changes and drive cautiously in neighborhoods. Citizen cooperation and patience is appreciated.
