A west-end school bus station managed to finish its morning run just before 10 a.m. Thursday after a large gas leak caused delays anywhere from 15 minutes to an hour.

The last few First Student Canada buses pulled up to schools just at about 9:50 a.m., said Laura Goulet, assistant location manager for the company's bus station at 1027 Moodie Dr.

The station holds about 110 school buses servicing Kanata, Manotick, Barrhaven and other west-end areas.

Moodie Drive was closed between West Hunt Club Road and Fallowfield Road before 6 a.m. because of the gas leak. The leak was capped by 8:30 a.m. and Moodie Drive has reopened, police said.

At about 8:45 a.m. Goulet said all of the station's buses were on the road. About 30 per cent of them were facing delays of anywhere between 15 minutes to an hour, she said, mainly in the Uplands area, the south side of Barrhaven and Parkwood Hills.

Large gas line feeding asphalt company failed

Fire department spokesman Marc Messier said a large gas line feeding Coco Paving Inc. at 994 Moodie Dr. failed, causing the leak.

The cause of the failure hadn't been determined early Thursday, Messier said.

Goulet said police and firefighters began allowing school bus drivers in and out of the area after the road was closed, but from 6:35 a.m. to 6:55 a.m., traffic was completely closed off.

"So anyone that was in here, we were staying here, and anyone that was outside couldn't get in," she said.

By 7 a.m., when bus drivers were once again allowed in and out of the affected area, significant traffic delays were making it difficult for drivers to get into work and leave again, Goulet said.

The Ottawa Carleton District School Board issued a notice to parents early Thursday warning that bus pickups could be "delayed significantly."
