The Tri-town Vision covers a 700-acre swath of land extending across I-93 into Andover, Tewksbury and Wilmington. Agfa, Wyeth Pharmaceuticals, and Proctor & Gamble are located within the study area and major new regional commercial development is being proposed. To allow the expansion of those businesses and generate new economic development, a new highway interchange off I-93 is being considered. Harriman provided the three communities with a unifying land planning vision that will drive those access improvements based on land use choices. The vision supports the growth of sustainable mixed-use development and high-tech/biotech industries.
