Tweed New Haven Regional Airport has filed inland and tidal wetlands permit applications with the state Department of Energy and Environmental Protection for the airport’s proposed expansion, including runway extension, a new eastside terminal and associated parking and roads. The expansion first was announced on May 6, 2021 — at the same time that city and Tweed officials, joined by Gov. Ned Lamont, announced that Avelo Airlines would begin service to and from Tweed. The relatively short length of Tweed’s runway and its small terminal — along with road access that currently cuts through a largely residential neighborhood in the Morris Cove section of New Haven’s East Shore — have long inhibited Tweed’s efforts to grow. The proposed expansion includes expanding Tweed’s one remaining runway from the current 5,600 feet to 6575 feet, construction of a new 80,000-square-foot terminal on the East Haven side of the airport — which straddles the New Haven-East Haven border — and infrastructure improvements.
