“Principal arterial” means a street which expedites movement of traffic to major traffic generators such as to a central business district, regional and major community shopping center, commercial service district, college or university, military installation, and from community to community. It also collects and distributes traffic from freeways and expressways to less important arterial streets, or directly to traffic destinations. (Ord. 2020 § 2, 1994; Ord. 1343 § 3, 1983)
