The Iowa National Guard says the roar of F-16 fighter jets could be more noticeable in the next few weeks in the Des Moines area because of construction at the city's airport.

Col. Greg Hapgood says the replacement of a taxiway and temporary closure of one runway at the Des Moines airport has forced Air National Guard pilots to use another runway. That could mean the F-16s will fly lower and be louder than usual over parts of the Des Moines area, especially areas of the city's south side near the airport.

Hapgood says most flights occur during the day, but some may also happen at night.

The construction is expected to be finished in October, allowing planes to return to their normal runway.
