The street layout of Seattle is based on a series of disjointed rectangular street grids. Most of Seattle and King County use a single street grid, oriented on true north. Near the center of the city, various land claims were platted in the 19th century with differently oriented grids, which still survive today. Distinctly oriented grids also exist in some cities annexed by Seattle in the early 20th century, such as Ballard and Georgetown. A small number of streets and roads are exceptions to the grid pattern.

Transportation in Seattle is largely focused on the automobile like many other cities in western North America; however, the city is just old enough for its layout to reflect the age when railways and trolleys predominated. These older modes of transportation were made for a relatively well-defined downtown area and strong neighborhoods at the end of several former streetcar lines, now mostly bus lines.
As with many large cities, a large number of Boston-area streetcar lines once existed, and many continued operating into the 1950s. However, only a few now remain, namely the four branches of the Green Line and the Ashmont–Mattapan High-Speed Line, with only one running regular service on an undivided street.
