An interchange is an intersection that uses grade separation and interconnecting ramps to permit some traffic to pass through the intersection without directly crossing any other traffic stream. An interchange can improve traffic operation and safety at a site by removing or reducing conflict between traffic movements. However, interchanges can result in cyclists being required to cross high speed on and off ramps.
Cycling on motorways is permitted where such operation is approved (Transit New Zealand Act 1989 Clause 83 (b)(external link)). Pedestrians do not have access to motorways. This may be relevant if the interchange includes a motorway.
In addition, legal aspects that apply to intersections and crossings also apply to interchanges depending on how they are configured.
CloseAustroads Guide to Road Design Part 4C Interchanges (external link)and Austroads Guide to Traffic Management Part 6(external link) outline design considerations for cyclists, and in particular suitable treatments for cyclists at interchanges.
Refer to uncontrolled crossings, signalised crossings and grade-separated crossings for further design information pertaining to interchange design for cyclists.
