The Portland airport is getting $12.7 million to build a runway safety area and rehabilitate parts of the runway and taxiway.

The Brunswick airport will use its $4.2 million grant to buy snow removal equipment and improve utilities and runway lighting.

The Augusta airport’s $5.2 million grant will go toward improving the runway.
