The map below illustrates the Public Works Department's plowing schedule. Priority 1 streets are plowed first. Then a first pass is made at priority 2 streets, followed by plowing on priority 3 streets and cul-de-sacs. The major arteries through Garner—U.S. 70, U.S. 401 and I-40—are plowed by NCDOT.
