The Sir John A. Macdonald Parkway, formerly the Ottawa River Parkway, is a four-lane scenic parkway along the Ottawa River in Ottawa, Ontario, Canada. It runs from Carling Avenue near Connaught Avenue, to Booth Street at the Canadian War Museum and National Holocaust Monument. It is maintained by the National Capital Commission. The speed limit is . Bicycles are allowed on the road and on a parallel recreational path along the parkway. Besides being a scenic route, it serves as a commuter artery for westend residents who work in the downtown area, particularly government employees who work at the Tunney's Pasture office complex, and other areas. It is also used by the transit systems of Ottawa and Gatineau for express buses. Route description The Parkway begins with on and off-ramps from Carling Avenue. The interchange is also the site of the Lincoln Fields Transitway station, with access driveways for OC Transpo buses. The Parkway proceeds north, passing under Richmond Road, then curving eastward along the Ottawa River. The Parkway follows the shore, with both directions separated by a grass median. The area along the river is mostly cleared of trees, allowing a view of the River and far shore line. The area to the south is partially forested, separating the roadway from residential areas to the south. Approximately 1 km from the start of the Parkway, is the Deschenes Rapids scenic lookout area. Driveways connect the two directions of the Parkway to the area, which has a small parking lot and picnic areas. The road meets Woodroffe Avenue a few hundred metres east. Northbound Woodroffe Avenue traffic joins the Parkway's eastbound lanes, while traffic from both directions of the Parkway are allowed onto southbound Woodroffe. The roadway continues east along the river shore until a signalized intersection with the OC Transpo Transitway. From this point east, the roadway is for the exclusive use of non-commercial vehicles and bicycles. The Parkway follows the river bank to the north, while the Transitway diverges east along an old railway right-of-way. The next landmark on the Parkway is Kitchissipi Lookout and Beach. The beach is also known as Westboro Beach. The Parkway passes over a pedestrian access walkway from the residential area to the east, with an intersection to the beach parking area. The beach is provided with a pavilion overlooking the River and the beach, which has changing rooms and a restaurant patio.
