OK, this is definately just a nerd point but there are road bonuses in and around the waterways in Tazoon that I'm sure aren't supposed to be there.
The southern U shaped bend 23726 , 25010/ 23606 , 25062
the strip between the buildings around the foot bridges near the southern end
23645 , 25020/ 23654 , 25020
The far north end of the waterways 23569 , 25306/ 23750 , 25461
the first waterway from the north end 23619 , 25290/ 23733 , 25324
Iwent over all the waterways but not all the paths and walkways so there maybe more out there .... I will post an update if I find any more :-)
