Seattle is committed to becoming the most bicycle-friendly city in the country. The Seattle Department of Transportation (SDOT) designs transportation projects to make walking, biking, and riding transit great travel options. Every year, SDOT installs new bicycle lanes and shared lane markings (sharrows), and constructs new bike trails and greenways to make it easier to get around the city by bike.
Safety is SDOT’s most important priority. The long-term goal is a city with zero traffic fatalities and serious injuries. The SDOT bike program also educates cyclists and motorists on the rules of the road, how to use new bike improvements being added to our streets, and distributes bicycling guide maps.
Seattle Bike Map
One of SDOT’s most popular publications is the Seattle Bike Map. The map presents information about cycling in Seattle in a clear, easy-to-use, and friendly format.
Seattle’s bike map is updated annually to reflect progress made in building the 450-mile bikeway network recommended in the Seattle Bicycle Master Plan. Over the last four years, SDOT has invested nearly $36 million in bicycle improvements guided by the plan and include 129 miles of bike lanes and sharrows, 98 miles of signed routes, and 2,230 bike parking spaces.
