Ottawa Regional Road 174

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.

The segment between the Highway 417 junction to Trim Road is a four-lane freeway with OC Transpo lanes in each direction from just east of Blair Road to Place d'Orleans. East of Trim Road, it becomes a two-lane rural highway until the Prescott-Russell county line where it becomes Prescott-Russell County Road 17 until the eastern end at Highway 417 east of Hawkesbury. Over the past few years, traffic between Highway 417 and Rockland became much heavier due to suburban growth in Orléans and Rockland leading to frequent congestion during peak hours. Meanwhile, the easternmost portion of the road was regarded as dangerous due to several fatal accidents. In 2007, both the provincial and federal governments committed funding for the widening of Ottawa Road 174 between Trim Road and Rockland, although the widening project was still several years away. However, in April 2008, Ottawa City Council refused a $80 million funding from both provincial and federal governments citing it would not benefit Ottawa, which delayed the construction indefinitely.
