Wikipedia:WikiProject U.S. Roads/Delaware/Maintenance road numbers

Every road with one of these numbers (listed in the traffic counts) is presumably state-maintained, with some also having signed numbers. Low numbers (and all signed routes) are listed here, as they are presumably the main or old main roads.
