Shoulder Lane is an Inside Shoulder or Outside Shoulder

Unlike other lanes, a Shoulder Lane can exist only on the left or right side of a Conduit. So, at most, there can be only two Shoulder Lane’s per Conduit. Furthermore, the inner Shoulder Lane’s Inner division must be the Conduit’s innermost Lane Division. The outer Shoulder Lane’s outer Lane Division must be the Conduit’s outermost Lane Division.
