A commercial runway at Baton Rouge Metro Airport that was closed by a light malfunction Sunday night was repaired overnight and is back in operation, according to Ralph Hennessy, the airport's assistent director of aviation.

Airport operations are back to normal this morning, Hennessy said, and passengers whose travel plans were disrupted by the closure are being rebooked on new flights.

The electrical problem happened about 8 p.m., causing the runway lights to go out, Baton Rouge Airport Spokesman Jim Caldwell said. Hennessey said the problem was discovered before midnight and repaired before daybreak.

The airport has two primary commercial runways, Caldwell said, but the other one has been shut down the past several weeks for repairs.
