Bangor is getting a grant to expand the city’s airport. $579,000 federal dollars will help expand the building’s facilities, as well as airplane maintenance. Officials from the Economic Development Administration joined Congressman Mike Michaud and local economic development leaders, for a tour of the project site. The EDA says Monday’s investment will lead to 70 high paying positions. Funding will go towards renovating a 1,700 square foot hangar, upgrading an aircraft painting facility, boiler room upgrades, and purchasing new systems for air and water treatment.
