The freeway merges with Ottawa Regional Road 174 (also known as the Queensway) at a large two-level interchange known locally as the Split, curving to the west and into downtown Ottawa. This reunites Highway 417 with the former Highway 17, that portion which was renamed as Regional Road 174. The interchange also provides access to Aviation Parkway from westbound Highway 417 and from the parkway to eastbound Highway 417. West of this junction, Highway 417 assumes the route name of the Queensway.
