 The majority of the city has a system of gridded streets oriented in relation to A Street (one block east of Pacific Avenue) and 6th Avenue or Division Avenue, both beginning in downtown Tacoma.Within the city, and with a few exceptions, east-to-west streets are numbered and north-to-south streets are given a name or a letter.Some east-to-west streets are also given names, such as S. Center St. and N. Westgate Blvd.
