The Trans-Canada Highway is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476 km (4,645 mi) across the country, one of the longest routes of its type in the world. The highway system is recognizable by its distinctive white-on-green maple leaf route markers, although there are small variations in the markers in some provinces.
King's Highway 17, more commonly known as Highway 17, is a provincially maintained highway and the primary route of the Trans-Canada Highway through the Canadian province of Ontario. It begins at the Manitoba boundary, 50 km (31 mi) west of Kenora, and the main section ends where Highway 417 begins just west of Arnprior. A small disconnected signed section of the highway still remains within the Ottawa Region between County Road 29 and Grants Side Road. This makes it Ontario's longest highway.
Route 2 is a major provincial highway in the Canadian province of New Brunswick, carrying the main route of the Trans-Canada Highway in the province.

Formerly known but still commonly referred to by both the public and the government as the F3 Freeway, Sydney–Newcastle Freeway, and Sydney–Newcastle Expressway, it is part of the AusLink road corridor between Sydney and Brisbane. The name "F3 Freeway" reflects its former route allocation before it was decommissioned and replaced by the rollout of alphanumeric signposts.

The highway was originally called the King's Highway, however, this name is no longer applied to the entire road. The only remaining historic section of the highway that maintains the name "King" is King's Road in Sydney.

A two-lane expressway or two-lane freeway is an expressway or freeway with only one lane in each direction, and usually no median barrier. It may be built that way because of constraints, or may be intended for expansion once traffic volumes rise. The term super two is often used by roadgeeks for this type of road, but traffic engineers use that term for a high-quality surface road. Most of these roads are not tolled.
The Cobequid Pass is the name given to a 45 km (28 mi) tolled section of Nova Scotia Highway 104 between Thomson Station, Cumberland County and Masstown, Colchester County in the Canadian province of Nova Scotia. The section is a public–private partnership; the highway is owned by the Highway 104 Western Alignment Corporation, a Crown corporation of the Government of Nova Scotia, with a toll plaza operated under contract by Atlantic Highway Management Corporation Limited, a subsidiary of Aecon Concessions. The toll plaza is located near the halfway point in Londonderry. It opened in 1997.
