The NCR has several major freeways including the 417, 416, 5, 50, 174, 7, and the Sir John A. Macdonald Parkway.
The 417 is Ottawa's major east-west commuter expressway. It begins at the Ontario-Quebec border (continuing the route of Quebec Autoroute 40), reaches the urban portion of Ottawa at the 417-174 split, bisects the urban area, and continues westward to just beyond the city boundary where it gives way to Highway 17 in Renfrew County.
The 416 starts at the 401 near the Ogdensburg-Prescott International Bridge and continues north for 75 km until it ends at the 417 in Ottawa's west end.
The freeway section of Highway 7 branches off the 417 in Ottawa's west end near Stittsville and is currently undergoing a 4-lane expansion to reach the eastern fringe of Carleton Place at McNeely Avenue. As of July 2011, the expansion was complete through to Ashton Station Road.
Public transportation is handled by OC Transpo on the Ontario side, and the STO on the Quebec side. Together they serve a population over 1,130,761 and have an estimated annual ridership of over 113.2 million.
OC Transpo operates a Light Rail Transit (LRT) system named the O-Train. The system uses Bombardier Talent Trains and has just over 2 million riders per year. A massive LRT expansion is currently in development to link the western suburbs and the eastern suburbs to downtown, as well as to continue southward expansion. The first phase will be a 12.5 km east-west lrt metro including 13 stations, 3 of which will be underground in downtown Ottawa while Gatineau is building a bus transitway, the Rapibus.
OC Transpo has about 1,050 buses which run on city streets and an expansive Transitway. The STO has around 300 buses that serve the Quebec side of the Ottawa River, some routes crossing into downtown Ottawa.
Ottawa Macdonald-Cartier International Airport is the main international airport serving the Capital Region.

It offers non-stop flights to and from Canada, the United States, Caribbean and Europe. It is part of the three busiest air routes in the nation, with hourly flights to/from Montreal-Pierre Elliott Trudeau International Airport and Toronto Pearson International Airport.
