Highway17B through Ottawa somewhat followed the route of Highway17 prior to the building of the Queensway, although it changed in subsequent years. Until the early 1960s, Highway17 followed
Carling Avenue,
Bronson Avenue, Laurier Avenue, and eventually
Rideau Street and
Montreal Road, as it passed through Ottawa. Construction of the Queensway resulted in frequent changes to Highway17. While the first section opened on November25, 1960, the full route through Ottawa was not completed until the central section was opened on October28, 1966. Following this, the Highway17 designation was applied along the Queensway. Consequently, the Highway17B designation was applied through Ottawa, following former portions of Highway17. The 1967 Ontario Road Map shows Highway17B beginning at the intersection of Carling Avenue and Pinecrest Road; it followed Richmond Road,
Wellington Street, Rideau Street, and Montreal Road to end at the
interchange with
Ottawa Road 174 (then a portion of the Queensway). This route remained until 1970. Highway17B reappears in the 1977 edition of the Ontario Road Map, following Richmond Street from its interchange with the Queensway. From there it continued to Churchill Avenue, which it followed north to Scott Street. Scott Street travelled east to Wellington Street, which connected to Rideau Street and Montreal Road to end at the Queensway at
Beacon Hill North. This route remained in place until 1982, after which Highway17B followed Carling Avenue, thence easterly to Bronson Avenue. It then headed north along Bronson to the one-way pair of Chamberlain Avenue eastbound and Catherine Street westbound between Bronson and another pair of one-way streets:
Kent Street northbound and
O'Connor Street southbound. It travelled along those streets between Catherine/Chamberlain and Wellington Street, and thence easterly, passing
Parliament Hill. The route then continued easterly along Rideau Street and Montreal Road to the Queensway. Highway17B continued to exist up until 1998, when it was decommissioned and transferred to the city of Nepean, city of Ottawa, city of Vanier and city of Gloucester. The route was likely maintained under a
Connecting Link agreement with the City of Ottawa, as it is not listed in the April 1997 or January 1998 highway transfer lists, nor the 1989 or 1997 highway distance tables, yet appears up to the 1996 Ontario Road Map. == Sault Ste. Marie ==
