Scope for phase 2 involves relocating the facility’s gas service and building the exterior shell for the expanded terminal building. The 41,000 square foot expansion is part of the airport’s 4-phase passenger terminal modification project. The new space will include a new security screening area, two additional boarding bridges, a service animal relief area, family restrooms, a nursing room, an expanded departure lounge, added room for concessions, and renovations to accommodate people with disabilities. Phase 1 included the basement construction of the expansion and was completed in 2020.

Additional phases in the plan include improvements to the original terminal itself, including electrical work and other interior updates. Completion of the 4th and final phase is expected by late 2023.
