People living in southeast Winnipeg are getting relief after months of heightened airplane noise.

A runway at the James Armstrong Richardson International Airport that was shut down for upgrades since April reopened on Thursday.

The $8.2-million project to rehab 3,352 metres of the north-south runway resulted in planes being rerouted to the northwest-southeast runway.

Southeast Winnipeg, which typically gets about 10 per cent of air traffic passing by, was instead getting nearly 100 per cent — and some of that in the middle of the night.

Many residents flooded the airport authority's 24-hour noise complaint line.

"For sure by the overnight hours, we should have all that traffic movement back to normal," said Winnipeg Airports Authority spokesperson Felicia Wiltshire.

"So hopefully, people will start to notice that the air traffic patterns, and air noise, will be more what they're used to."
