The U.S. General Services Administration (GSA) has completed a key environmental review for the planned Coburn Gore Land Port of Entry expansion and modernization project in Maine, clearing the way for the next phase of planning and development. The federal effort estimated to cost up to $146.6 million and scheduled to begin construction in summer 2028.
The project will upgrade the existing border crossing to improve operational efficiency, security, and cross-border coordination with the adjacent Canadian port of entry in Saint-Augustin-de-Woburn, Quebec. The scope includes expansion and redevelopment of the current facility while preserving key historic elements, including the original main port building and associated housing.
The redesign will reorganize circulation, inspection areas and public-facing functions so the port can operate more effectively. Plans incorporate accessibility improvements and sustainability measures to lower emissions, reduce long-term environmental impacts and improve long-term resilience. When complete, the upgraded crossing is expected to improve freight movement, support regional commerce and modernize a key security checkpoint on the border.
GSA recently issuing a Final Environmental Assessment and Finding of No Significant Impact, allowing the project to move into the next phase. Design development is currently underway, with an architect-led scheme being prepared for review and approval. A construction manager as constructor (CMc) award is anticipated in summer 2026, followed by construction starting in summer 2028. Substantial completion is expected by spring 2030.
