As the fastest growing city in the nation, Seattle's transportation infrastructure is under tremendous stress. As an interested citizen, information about our transportation system can be confusing and difficult to find. TransitSphere, built in partnership with the Seattle Department of Transportation, is an easy, interactive way to discover how Seattle's transportation assets work together to keep us moving. This tool gives citizens the how, what, and why of our city's transportation infrastructure management, and can serve as an introduction to a part of their government that they may not be familiar with.
