Hi. I hope all Delaware editors have read the announcement about the new U.S.-wide system for setting road types: https://www.waze.com/forum/viewtopic.php?f=129&t=89435.
I went through Sussex County and the lower part of Kent (south of Rte 14) last week, and brought everything into compliance with the new standard. Fortunately, it didn’t require a huge number of changes, but it is time-consuming. (And I don’t guarantee 100% accuracy, so if someone else would like to check my work, go for it!)
The part of the state north of Rte 14 still needs to be checked, as far as I know. If anyone has done other areas, please let us know. Links to the DDOT Functional Classification maps can be found at https://wiki.waze.com/wiki/National_resources/USA/Functional_classification.
