Ottawa Road 174, formerly referred to as Ottawa-Carleton Regional Road 174 and commonly referred to as Highway 174, is a city maintained road in the City of Ottawa which serves the eastern suburbs of Orléans and Cumberland. Although the road continues through the towns of Rockland and Hawkesbury to the Quebec border, the portion east of the Ottawa city boundary is known as Prescott and Russell County Road 17. Originally the alignment of Highway 17 between Ottawa and the Quebec border, Regional Road 174 (as it was known then) was created on April 1, 1997 when the provincial government of Mike Harris transferred responsibility for portions of the road to the Regional Municipality of Ottawa–Carleton. The road was extended by a second transfer on January 1, 1998, bringing it to its current length.
