Limit on ramps and bridges?

[Luca]

I didn't realize there were a limit on any PWP, but I just saw someone say there's a limit of 8 ramps. Is that true, and is there a similar limit on bridges?

 

[seliph]

seems so, bridges is 8 as well

Yeah, unfortunately there is a limit of 8 bridges and 8 inclines. Really messed up a couple of my plans, lol.
