Add Widenings
12. Tap the Widenings tab. We will define a
widening where a new lane will begin in
the right side of the road.
13. Tap <End> in the Right column and then
tap the Add… button. This opens the Add
Right Widening screen, which allows you to
add a widening to the right side of the road
14. In the Start Station field, enter 0+25. This
is where the widening will begin.
15. The length of the widening is 100 feet so
toggle the End Station button to Length
and enter 100.
16. The starting width of a widening must
equal the width of the first segment of the template that leads
into the widening, or if a previous widening leads into it, it must
equal the width of the previous widening. Leave the Starting
Width
field set to its default value of 20.
17. Since we are adding a lane with this widening, enter 40 in the
Ending Width
field. This widening will now begin at 0+25 and
over a 100-foot span; the first segment of the template will
increase in width from 20 feet to 40 feet. Bold lines in the map
view illustrate the beginning and ending widths of the widening.
18. Tap to continue.
