The main segment of Centre Street is an arterial road extends from 9 Avenue S, at the base of the Calgary Tower in Downtown Calgary. The roadway passes through Chinatown, crosses the Bow River, to the Beddington Boulevard, after which it becomes a residential street and becomes unavailable to private vehicular traffic north of Bergen Crescent (the road continues, but it is only accessible to Calgary Transit and emergency vehicles). The road resumes immediately north of the "bus trap" at Beddington Trail, where it continues as Harvest Hills Boulevard. When the roadway crosses Stoney Trail, the name reverts to Centre Street N and the road continues north and exits the city limits at Highway 566.
