Alberta Numbered Highway Network
highway system
The Alberta Numbered Highway Network is the provincial highway network of Alberta, Canada, consisting of all the roads, bridges, and interchanges that are managed and maintained by the Ministry of Transportation and Economic Corridors (TEC), a department within the Government of Alberta. The network is extensive and one of the largest highway networks in Canada, with over 64,000 lane kilometres of roads (equivalent to 31,400 kilometres [19,500 mi]) and over 4,900 bridges and interchanges making up the network. Additionally, around 58,000 lane kilometres (equivalent to 28,400 kilometres [17,600 mi]) of the roads in the network are paved, while the remaining roads are unpaved. The longest highway in the network is Highway 2 with a total length of 1,273 kilometres (791 mi), while the shortest is a segment of Highway 3A allowing access to West Lethbridge, at a length of 0.65 kilometres (0.40 mi).
The broader road network within the province, including roads within its highway network, has a total length of over 473,000 kilometres (294,000 mi) of single-lane equivalent roads as of April 2018.
Regulations
In Alberta, all public and private roads are legally considered highways under the Traffic Safety Act (TSA). The TSA sets forth the traffic regulations and the rules of the road that regulate and control the use of the road infrastructure within the province, including major highways. Additionally, the definition of highway as defined in the Act is broad in nature, with "any thoroughfare, street, road, trail, avenue, parkway, driveway, viaduct, lane, alley, square, bridge, causeway, trestleway or other place or any part of any of them, whether publicly or privately owned, that the public is ordinarily entitled or permitted to use for the passage or parking of vehicles" being defined as a highway and therefore subject to the Act and its related regulations. The Highways Development and Protection Act (HDPA) additionally sets the regulations and responsibilities of the Government of Alberta regarding all roads and highways under its ownership and authority.
Speed limits on provincial highways are regulated by the Traffic Safety Act, and vary between 50 and 100 kilometres per hour (31–62 mph) depending on the type of highway.

Why this record matters
“Alberta Numbered Highway Network” is worth following because a concise public description often conceals a longer documentary argument. Here, Alberta, Numbered and Highway provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 13, 2026. The linked authority identifier is Q24273207. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
