MADAWASKA, Maine — With two massive federal infrastructure projects coming to Madawaska this summer, construction promises to transform the face of the downtown area, though final details on both projects remain uncertain. Both the Land Port of Entry and the International Bridge have set construction start dates in the coming months, with Reed & Reed, the bridge builders, looking to move trailers into town by the end of April. Meanwhile, there is no official or impending start date for the LPOE project, with the General Services Administration saying only that the current timeline marks summer 2021 for the site preparation.
