Transit Lanes
There are different types of priority that help buses and streetcars to move faster and more reliably on city streets, and a marked transit lane is one of the most critical. As of 2025 there are over 54 lane-miles transit lanes citywide. Not all transit lanes are identical: they can vary in hours (some are 24/7, some peak only) and restrictions (some allow access to businesses, others are exclusive to transit).
This map shows the location of both existing and planned transit lanes in the city. A planned lane is included only once there are completed, public engineering designs.
There is a separate line on the map for each distinct lane, for example, a street with lanes in both directions will have two lines, and in some cases, lanes may even be portions of blocks. In addition to hours and restriction information, each lane has data about the physical configuration of the lane, such as if the lane is on the left or right, and the number of driveways off the lane.
This data is maintained by Seattle Department of Transportation. It is provided as-is with no guarantee as to correctness. It may only be used for general analysis purposes and may not be used as an official statement as to the current or future allowed uses of any lanes in the city.

This layer is intended for public use.
Refresh Cycle: Static, manually updated as required. Data is updated by SDOT via spreadsheet and script output JSON then final output as Shapefile.
