The airport's main runway is scheduled to get a facelift as part of routine maintenance this July. Contractors will be grinding off the top layer of old asphalt, applying a new surface and stabilizing the runway's shoulders.
Horizon will be able to use the airport's secondary runway, but Delta won't be able to operate during the construction.
Airport Manager Bruce MacLachlan said when the temperatures start climbing, it takes more runway for any typical aircraft to land especially the type Delta uses.
"With the particular aircraft Delta operated they felt that it was too close and they didn't want to jeopardize the safety so they wanted to make sure that the aircraft within it's designed safety characteristics and safety envelope," said MacLachlan. "And so they made a decision to go ahead and not fly during those two weeks."
The original runway was built in the late 1960's. It's only been re-constructed once since then. Work will start on July 14th and is expected to last 14-days. Delta won't fly in or out of Lewiston until the main runway is back up and running.
