Maine Department of Transportation’s Acadia Gateway Center reduces traffic congestion on local roads and in village areas by providing long-term parking for carpools and offering transit services to Mount Desert Island. The $30 million intermodal gateway center also serves as the main hub for the Downeast Explorer, which is the transit service provider on Mount Desert Island. The facility is also equipped with 17 publicly accessible electric vehicle charging stations and offers regional information, enhancing visitors’ understanding of Downeast Maine and directing customers to local businesses and attractions beyond the park’s borders. The Acadia Gateway Center integrates innovative sustainable technologies—including a large rooftop solar array, a geothermal heating and cooling system, and advanced energy management controls—to create a “net zero ready” facility that reduces its carbon footprint and long-term utility costs. By combining renewable energy, intermodal design, and smart building systems, the Gateway Center serves as a model for resilient, low-impact transportation facilities in environmentally sensitive areas. The Maine DOT added that the Infrastructure Investment and Jobs Act provided critical federal funding that supported the design, construction, and construction oversight of the Acadia Gateway Center – helping advance the project from planning to completion, ensuring the facility met high standards for sustainability, accessibility, and multimodal connectivity.
