 An example is the Tuggeranong Parkway which links Canberra's CBD and Tuggeranong, and bypasses Weston Creek.In most districts, discrete residential suburbs are bounded by main arterial roads with only a few residential linking in, to deter non-local traffic from cutting through areas of housing.In an effort to improve road safety, traffic cameras were first introduced to Canberra by the Kate Carnell Government in 1999.
