The capital city of Canada is also served by a network of freeways, the main one being provincial Highway 417 (called The Queensway), Ottawa-Carleton Regional Road 174 (formerly Provincial Highway 17), and Highway 416 (Veterans' Memorial Highway), connecting Ottawa to the rest of the 400-Series Highway network in Ontario. Highway 417 is also the Ottawa portion of the Trans-Canada Highway. The city also has several scenic parkways (promenades), such as Colonel By Drive, Queen Elizabeth Drive ,the Ottawa River Parkway, Rockcliffe Parkway and the Aviation Parkway and has a freeway connection to Autoroute 5 and Autoroute 50, in Hull.

Public transit.
See also: Ottawa Rapid Transit:
The public transit system is operated by OC Transpo, a department of the city. An integrated hub-and-spoke system of services is available consisting of:  regular buses travelling on fixed routes in mixed traffic, typical of most urban transit systems; a bus rapid transit (BRT) system - a high frequency bus service operating on the transitway - a network of mostly grade-separated dedicated bus lanes within their own right-of-way and having full stations with Park & Ride facilities further supported by on-road reserved bus lanes and priority traffic signal controls;  a light rail transit (LRT) system known as the O-Train operating on one north-south route; and (4) a door-to-door bus service for the disabled known as ParaTranspo. Both OC Transpo and the Quebec-based Société de transport de l'Outaouais (STO) operate bus services between Ottawa and Gatineau. A transfer or bus pass of one is accepted on the other without having to pay a top-up fare on regular routes.

Navigable waterways:
Ottawa sits at the confluence of three major rivers: the Ottawa River, the Gatineau River and the Rideau River. The Ottawa and Gatineau rivers were historically important in the logging and lumber industries, and the Rideau as part of the Rideau Canal system connecting the Great Lakes and Saint Lawrence River with the Ottawa River. The Jock River runs through the southern portion of the city, east through Richmond, and pours into the Rideau River near Manotick. It is a small tributary and is popular for canoeing and kayaking.
The Rideau Canal, which starts in Kingston, Ontario, winds its way through the city. Just past Mooney's Bay the waterway splits into two separate channels. The western channel is a navigable canal which flows through the core of the city and terminates at a large and dramatic set of locks between Parliament Hill and the Chateau Laurier Hotel. The eastern channel is kept in a natural state and meanders through the eastern side of downtown, terminating at the beautiful Rideau Falls, after which the river itself was named. Rideau is a French word that means 'Curtain' in English, and the falls resemble a curtain, hence the name. During the winter season the navigable west canal is usually open and is a form of transportation downtown for about 7.8 kilometres (4.8 mi) for ice skaters (from a point near Carleton University to the Rideau Centre) and forms the world's largest skating rink. Many residents use the canal as a way to get to work instead of taking cars or public transportation.

Bicycle and pedestrian pathways:
There is a large network of paved multi-use pathways that wind their way through much of the city, including along the Ottawa River, Rideau River, and Rideau Canal. These pathways are used for transportation, tourism, and recreation. Because most streets either have wide curb lanes or bicycle lanes, cycling is a popular mode of transportation in the region throughout the year. On Sundays very popular avenues and streets are completely blocked off to motorists so people can enjoy roller blading, cycling, and other activities. There are over 220 kilometeres of paths located throughout the Ottawa-Gatineau region. There are also some downtown streets that are restricted to only bicycle or pedestrians.
