Issue description
For some reason a particular piece of a bridge is not being built - even though I have resources available for it. trucks do not drive to the part (even with urgent priority) I also have 100 unity and using the unity tool says (not enough resources)
The other bridge parts built fine. I even removed the ghost and replaced. still nothing. It is not in planning mode.

Track priorities are healthy - maybe I am missing something obvious?
Thanks for the Game - Really great so far!
