This value, in combination with the Number of Lanes specified in the Widening Method, specifies the amount of widening to be applied on the left-side and or the right-side offset alignments. If Inside Only is used, then the widening value is increased to match the number of lanes on either side of the road (doubled if the number of lanes on the inside and the outside are the same), and applied on all of the inside offset for the widening. On the outside at these stations, no widening is applied.
