This is a great map! Thank you!

Nevermind, I found the problem! I had the highways mod downloaded from before, and I had it turned off. Turned it back on and it works fine.

Same thing happened to me, there's only a few bridges and parts of on ramps and off ramps but no highways. I have all the required mods, but still nothing. Looks like a really cool map though, I hope I can get it working

@jalang oops forgot to add the required mods. Just download those mods and I think the roads should come back.

There are no highway connections.
