The United States Postal Service is soliciting formal proposals for a new main post office on the island. A formal request for submissions was published by the St. John Source. It invites developers to propose a building that is "approximately 5,100 square feet on a site of approximately 52,000 square feet" within an area bounded by North Shore Road, the 104 Junction, Centerline Road and Wharfside. That suggests there are no plans for a mid-island facility or Coral Bay substation. Acceptable proposals would include a long term lease, or a new building constructed to U.S. Postal Service specifications. Offers will be accepted until Oct. 22.
