For branches that may be partly dead, yet have a good healthy lateral branch between the dead part and the base, cut off the branch with a good clean slanting cut close to and beyond the healthy lateral branch. Remove low hanging, unsound, o r unsightly branches on trees or shrubs designated to remain. Remove all branches or growth interfering with the free traffic movement on the highway. Trim branches of trees extending over the roadbed to provide a clear height of 20 feet (6 m) above the roadbed surface.
