The National Highway System: Overview 2007

In September 2005, the National Highway System was revised and expanded to reflect changes that occurred in Canada's population, economy and trading patterns since the system was first designated in 1988.

As of December 2006, the system encompasses 38,026 kilometres of key highway linkages in three categories:

Core Routes
Key interprovincial and international corridor routes (the original 1988 NHS routes, the September 2004 additions, and links to key intermodal facilities and major border crossings which connect with "core" routes)

Feeder Routes
Key linkages to the Core Routes from population and economic centres (including links to intermodal facilities and important border crossings)

Northern and Remote Routes
Key linkages to Core and Feeder routes that provide the primary means of access to northern and remote areas, economic activities and resources.

In April 2008 the Council of Ministers received a report on the National Highway System that provides an overview depiction of:

  • the condition of pavements and bridges on the system,
  • travel, traffic and safety performance, and
  • capital and rehabilitation investment by governments.
