there is one payItem associated with a corridor code set style that the quantity is way off.
It has 142 million square feet - this is 14,400x the location next to it - they are about the same size. The 144 seems like a inch:feet issue but may be a coincidence. The link is SubBase. A quick review of the Imperial - Lanes atc file and comparison with other lane objects shows they are consistent. I checked the corridor and surface - everything looks fine.
