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 continues east until a signalized intersection for access to the Tunney's Pasture campus of the federal government.

East of MacDonald Park at Vimy Place is the beginning of Wellington Street, which belongs to the City of Ottawa.

From Lincoln Fields to Dominion stations, it shares traffic with the Transitway rapid-bus network, as well as STO buses from Gatineau (between Tunney's Pasture and the Champlain Bridge).

[4] The trail was an instant success and has since been expanded to cover a distance of 16 kilometres (9.9 mi) stretching from the Canadian War Museum down to Westboro Beach.

[5] The winter trail is now in its fourth season and is jointly managed by the groomer (Dave Adams) and Dovercourt Recreation Centre.

At the time of its construction, Carling Avenue was part of Ontario Highway 17, and the Parkway provided an alternative, scenic drive to the parliamentary precinct.

The construction of the new Canada War Museum on Booth Street was done in conjunction with a re-routing of the section of the River Parkway in the area.

In 2015, the NCC and the City of Ottawa reached an agreement to run the light rail under a reconstructed and realigned Sir John A. Macdonald Parkway, from what will be Dominion to Cleary stations (East to West, roughly between present-day Churchill Avenue and Cleary Avenue).

Foreign Affairs Minister John Baird, MP for Ottawa West-Nepean, announced the change on August 15, 2012.

[7] The renaming followed a grassroots campaign led by author and historian Bob Plamondon and future mayor Mark Sutcliffe.

[9] On January 11, 2012, the former Wellington Street Bank of Montreal had been also renamed the Sir John A. Macdonald Building.

[10] In June 2021, after the discovery of a large number of potential unmarked graves at Kamloops Indian Residential School, city councillors Catherine McKenney, Jeff Leiper, and Theresa Kavanagh wrote to the federal government, asking they remove Macdonald's name from the parkway and find a new name based on consultations with local First Nations.
