A long-vacant plot along Route 13 in Dover could soon get a new purpose as the proposed DuPont Plaza shopping center moves closer to reality. The nearly 10-acre site, located between Tim Hortons and Citizens Bank, is one of the last undeveloped parcels along the busy retail corridor, but the shopping center could change that.

The old Dover Post Office, a long-vacant building in downtown Dover, may soon get a special delivery—a redevelopment transforming the site into a three-story, mixed-use space with commercial units and 36 apartments.
