The Parkway curves east and proceeds to a large intersection with Island Park Drive. Island Park connects north to Gatineau across a series of bridges and a park over the Ottawa River. The intersection's traffic lights are controlled to provide turning signals. Just east of the intersection is another park and lookout area, provided with driveways to a parking lot near the river. The Parkway continues east until a signalized intersection for access to the Tunney's Pasture campus of the federal government. An extra turning lane is provided to access the large parking lot of the campus. Further east, the Parkway passes over Parkdale Avenue, with on and off-ramps between Parkdale and the Parkway. A signalized intersection is provided to the east providing access to the Mechanicsville neighbourhood to the south, and Lemieux Island and its park and filtration station to the north, along an unnamed roadway. Access to and from the Parkway and this intersection is only allowed during off-peak hours. The Parkway continues east along the shore of Nepean Bay and into the LeBreton Flats area. The Parkway ends at Vimy Place, which is the roadway to around Lebreton Flats to get to the Museum of War. East of Sir John A MacDonald Park, at Vimy Place, is the beginning of Wellington Street, which belongs to the City of Ottawa (ref: Geo Ottawa GIS Map) Use by buses It is closed to commercial traffic, so the majority of vehicles are private cars. 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). Summer Sunday closures On Sundays during summer months (Victoria Day to Labour Day), the Parkway's westbound lanes are closed to motor vehicles and opened to pedestrian and bicycle traffic from 9 am until 1 pm. SJAM Winter Trail In 2016, the NCC approved a proposal to turn the parallel recreational path into a mixed use winter trail for cross country skiing, walking, snowshoeing and biking. The trail was an instant success and has since been expanded to cover a distance of 16 km stretching from the Canadian War Museum down to Westboro Beach. The winter trail is now in its fourth season and is jointly managed by the groomer (Dave Adams) and Dovercourt Recreation Centre. History The River Parkway was first proposed as part of Greber Plans for
