Cycle track
A cycle track, separated bike lane or protected bike lane (sometimes historically referred to as a sidepath), is an exclusive bikeway that has elements of a separated path and on-road bike lane. A cycle track is located within or next to the roadway, but is made distinct from both the sidewalk and general purpose roadway by vertical barriers or elevation differences.
