Here is the Steel Bridge with no pillars. This should help to go over wider obstacles. It’s kinda finicky tho where it doesn’t work all the time. It has problems when going over track that are on an angle but does work in many places.
In the images below, I went over a 12 track wide section to test this. In the first image, the Steel bridge will NOT work. But, in the second image, the ‘Steel bridge no pillars’ will work.
Try it out and let me know if it helps at all. If it helps and you want more, I can do the other bridges too.
EDIT: I forgot to remove the cost_mod entry from the .lau file and it crashed the game for some. I removed the info and reposted a v2 of the bridge. Sorry for any inconvenience it may have caused.
