This is my mod of Pongo width_road_x1.5.zip UX to provide:
2X is done testing*
2.5X is done testing*
3X is done testing*
I'm using the width profile of NextGen9.18.27.687519-Gift(26Jan2017) as baseline of 1X. It would seem that the old iGO/Primo (easy) way of changing road width didn't work for NextGen. Make sure you're using only one road width UX at a time.
* tested in 3D, 2D, and 2DN mode for NextGen9.18.27.676280-Israel(20Oct2016),NextGen9.18.27.687519-Gift(26Jan2017), NextGen9.18.27.689739-Basarsoft(10Feb2017), and NextGen9.18.27.693527-World(14Mar2017)
