# Road width variables that are used in road & bridge styles.

# Roads are drawn in two steps. First, a line if the width of the road + the
# two borders is drawn and then a line of the width of the road is drawn on
# top, to make a road with borders. Here, the width of the ways is the width
# of the fill of the road and the border width is the width of a single
# border, on one side (first line is drawn with a width of way with + 2 *
# border_width).
