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.
