MUSCLE SHOALS, Ala. (AP) -- The Northwest Alabama Regional Airport is in the midst of a roughly $1 million upgrade that officials expect to be finished by the end of the year.
Reports say the airport's last upgrade happened about 20 years ago and the building has started showing signs of deterioration in certain areas.
Officials say the upgrades are expected to improve the airport's energy efficiency. The upgrades call for building new interior walls, a new roof and installing moisture barriers to help alleviate problems that could cause water damage.
Mark Reiter, a project manager for the Michael Baker Corp. --the airport's aviation consultant -- says the upgrades will help begin to transition the airport into a transportation gateway to the Shoals.
