A new bus route in northwest Calgary neighbourhood of West Hillhurst has upset some of the residents.

Route 9 is one of 15 new routes launched this week by Calgary Transit, mostly in the northwest.

As part of the changes, standard size buses have replaced the smaller buses that serviced the Hillhurst-Sunnyside area. Every 15 to 30 minutes, a bus now travels the residential streets of West Hillhurst and around the corners of a playground zone.

There's now a bus stop outside Paul Lewandowski's home. "I can hear them vividly in my bedroom. Not only hear them, I can smell diesel."

Michelle Wang is among residents who say they've complained to the city. She says Memorial Drive is a close enough alternative.

"It's sending a message that 'We don't care that people want to use the park or cross streets. And we'll just use this as a thoroughfare,' when it's completely unnecessary."

Chris Jordan, a manager at Calgary Transit, says the changes were made using passenger and community input. But he adds they'll review the feedback on the new routes in the coming weeks.
