Road-Adjacent Greenway

CDR-RAG-05
Recommended Corridor

Road-Adjacent Greenway

A corridor where a multi-use trail or linear park runs parallel to, but physically separated from, a road for some or all of its length, without an active rail line involved, addressing connection points and crossing treatment between the two.

#Why this pattern exists

A greenway running beside a road is a common and valuable configuration, but it creates a specific design problem distinct from a road with no parallel path: where and how people move between the two, and how crossings of the road itself are handled where the greenway needs to cross it. Left unaddressed, this produces either a greenway that is disconnected from the destinations along the road, or unsafe informal crossing points.1

#Key considerations

  • Connection points between the road-side facilities and the greenway should be planned at regular, predictable intervals
  • Any point where the greenway needs to cross the road should use an appropriate Crossing-family Element pattern, not an ad hoc treatment
  • Distinguish this from Multi-Use Trail/Greenway (a Segment-scale pattern describing the trail itself); this pattern is about the trail’s relationship to the parallel road, not the trail’s own design
