Roles in Controlled Access Highways

>> Access to CA Highways
>> Controlled Areas
>> Section 80 Subdivisions

Section 48 of the Transportation Act is used to designate some highways as controlled access highways. These are usually numbered routes and are intended to carry higher volumes of inter-regional traffic. The Ministry has developed a Controlled Access Strategy which applies along controlled access highways and in controlled areas.

The intent of Controlled Access highways and Controlled Areas is to preserve a reasonable level of service to long-trip vehicles on the major highway and street system, and to enhance safety.

It is intended to:

  • promote a balanced hierarchy of road facilities in all areas
  • discourage urban sprawl in rural areas
  • limit points of access to trunk high-speed highways
  • regulate land use within the controlled area
