That plan, which has been in the works for nearly 15 years and was passed by the town in 2015, includes the Costco big box store — currently being constructed off Exit 74 — as well as an already existing 280-unit residential development at Exit 73 known as The Sound at Gateway Commons. The second phase of those residential developments soon will be given a formal name, said Newton C. Brainard, vice president of development and acquisition for The Simon Konover Co. of West Hartford, which is jointly developing the Gateway Commons site with KGI Properties of Providence.
