Please define a shared use path. If the main travel paths remain 2 lanes in each direction, what will divide them from the shared use path?

There would be a single face barrier to provide a substantial barrier plus the shared use path is essentially just a side path. There are different terms used to talk about very similar situations. With the location of the trail being detached from the roadway it would be considered a shared use path in this situation. There is a grass buffer as well, so they are not right behind the barrier. The shared-use path can function as any type of trail accommodating bikes, pedestrians, and other non-motorized vehicles.
