Transitway (Ottawa)

During the 1970s and 1980s, the Regional Municipality of Ottawa-Carleton approved the construction of a new transit corridor called the Transitway. The purpose of this busway was to increase the speed of city-bound services from east and west. The first two sections opened in 1983: the southwestern Transitway between Lincoln Fields and Baseline and the east between Lees and Hurdman.[1]

The central Transitway was then added in the Westboro and Mechanicsville areas. In the downtown core, buses traveled along dedicated lanes on Albert and Slater streets. The eastern Transitway was extended in both directions, towards Laurier in the northwest and Blair in the east. These segments of the Transitway were serviced by route 95, travelling the full length of the Transitway from Baseline to Blair. Priority measures were later added to Woodroffe Avenue and Regional Road 174, extending service into the suburbs of Barrhaven and Orleans.[1]

In the 1990s, a rail corridor was gradually converted into the southeast Transitway, spanning from Hurdman to South Keys. This new section necessitated the creation of route 97. Route 97 followed the new southwest Transitway before joining route 95 along the existing Transitway segments. The 97 was extended to service the suburb of Kanata. The Kanata section was later split off into route 96.[1]

In 2001, the O-Train's Trillium Line (then simply the "O-Train") opened. Its northern terminus was at the new Bayview station on the central Transitway and its southern terminus at Greenboro on the southeast Transitway.[2]

The southwest Transitway was gradually extended southward, first to Fallowfield in 2005 and then to Barrhaven Centre in 2011. A median busway section was added along Chapman Mills Drive to Nepean Woods in 2014. The first segment of the western Transitway opened in 2009 connecting Pinecrest and Bayshore. This was extended to Moodie in 2017.[3]

Beginning in 2015, sections of the Transitway closed for conversion to light rail for the Confederation Line. Buses were rerouted to bus-only lanes along Highway 417, Regional Road 174, and city streets.[4] The Confederation Line opened in 2019, along with a major re-organization of the Transitway network. Rapid routes no longer travelled through downtown Ottawa. Instead, all rapid routes use the Transitway to connect communities to the Confederation Line at one of three stations: Tunney's Pasture, Hurdman, or Blair. Routes were also renumbered to correspond with their geographic service area, resulting in the retirement of route 95, the Transitway's busiest and oldest route.[5]

Temporary Transitway bridge connecting Scott Street to Dominion Station

Multiple sections of the Transitway were permanently closed for O-Train Stage 2 construction in 2021 and 2022. In September of 2021, the Transitway was closed between Moodie and Bayshore, followed by the section between Bayshore and Pinecrest in April of 2022. Buses were detoured along Highway 417, with Moodie station being relocated to temporary bus stops at the interchange ramps, and some bus routes bypassing Pinecrest and Bayshore stations eastbound as a result.[6][7] In June, the entirety of the central Transitway between Tunney's Pasture and Dominion stations was closed, as well as the southwest Transitway between Iris and Baseline. Buses were detoured along Scott Street parallel to the former central Transitway, with a temporary extension and bridge connecting to Dominion Station. Buses were routed along Iris Street and Woodroffe Avenue between Iris and Baseline stations.[8]

The following are OC Transpo's rapid routes, which travel along the Transitway with frequent service connecting communities to the O-Train. Additional OC Transpo routes also use segments of the Transitway.
