Within Ottawa, the Queensway extends from Orleans in the east and passes just south of downtown through central Ottawa to Kanata in the west. Two major interchanges anchor either end of this section: in the east, Highway 417 diverges south towards Montreal at "the Split", while the Queensway continues east as Ottawa Regional Road 174 and Aviation Parkway branches north; in the west, Highway 416 travels south to Highway 401. The core section of the Queensway is eight lanes wide, four per carriageway.
