9.13.2 Bikeway Classes

Bikeways are designed according to classes.

9.13.2.1 Class I Bikeway

A Class I bikeway is intended for the exclusive use of bicycles.  While it may parallel a roadway, it is physically separated by distance or a vertical barrier.  Class I bikeway considerations include:

• A Class I bikeway provides the safest and most efficient means of bicycle travel and is the preferred option for bikeway development.

• Crossing of a Class I bikeway by pedestrians, train, or automobile should be minimized.

• If a Class I bikeway does not closely parallel a roadway, it should be designed to provide appropriate bikeway gradient and curvature.

• Class I bikeways require the greatest amount of space and advance planning to reserve land and assure appropriate routing.

• Railroad crossings should be well marked, with proper operating signals and clear sighting down the tracks.  Road crossing transitions should be smooth and well drained.

9.13.2.2 Class II Bikeway

A Class II bikeway shares the right-of-way with a roadway or walkway.  It is indicated by a bikeway pictograph on the pavement and a continuous strip on the pavement or separated by a continuous or intermittent curb or other low barrier.  Class II bikeway considerations include:

• Because some separation is provided for bicycle travel, a Class II bikeway provides some level of safety for the bicyclist and pedestrian.

• While crossing by pedestrians or automobiles is discouraged, they are not as controllable as they are on a Class I bikeway because the Class II bikeway is adjacent to the walkway or roadway.

• Because Class II bikeways are tied to the adjacent roadway or walkway, route selection is important to maintain appropriate bikeway gradient and curvature.

• Class II bikeways generally require less space than Class I bikeways because they follow the alignment of and share the right-of-way with a roadway or walkway.  

9.13.2.3 Class III Bikeway

A Class III bikeway shares the right-of-way with a roadway or walkway.  It is not indicated by a continuous strip on the pavement or separated by any type of barrier, but it is identified as a bikeway with signs.  Class III bikeway considerations include:

• Because no separation is provided, there is a higher potential for safety conflicts between automobiles and bicycles and between bicycles and pedestrians.

• Class III bikeways provide continuity within the bikeway network and designate preferred shared routes to minimize potential conflicts.  To maintain safety for bicyclist and pedestrians, Class III bikeways should be developed, if possible, only where automobile and pedestrian traffic is moderate to light.

• Because Class III bikeways share the roadway or walkway, route selection is important to maintain appropriate bikeway gradients and curvature.

lass III bikeways require the least space because they share the pavement with a roadway or walkway.
