Ontario Highway 417 - Route Description

Route Description

Highway 417 is a 181.4 km (112.7 mi) controlled-access highway that traverses the lower Ottawa Valley and upper St. Lawrence Valley, bypassing the generally two-lane Highway 17 and providing a high-speed connection between Montreal and Ottawa via A-40. The freeway has also gradually been extended northwest from Ottawa alongside the old highway to its current terminus in Arnprior. Highway 417 currently has 42 interchanges from the Quebec border to Arnprior, with more planned as the highway is extended westward. Unlike other highways in Ontario and most of North America, exits are numbered from east to west.

While a significant portion of Highway 417 is a rural four lane freeway divided by a grass median, the section within urban Ottawa is a busy commuter route as wide as eight lanes. The portion of the route from the Highway 7 interchange east to the Split – a large four-way interchange between Highway 417, Ottawa Regional Road 174 and the Aviation Parkway – is known formally as the Queensway, although no indication of this name appears on any signage.

    But however the forms of family life have changed and the number expanded, the role of the family has remained constant and it continues to be the major institution through which children pass en route to adulthood.
    Bernice Weissbourd (20th century)

    Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.
    Willard Van Orman Quine (b. 1908)
