The SR 99 Study is an ongoing WSDOT effort to reduce fatal and severe crashes and improve connections for people walking, biking, rolling, and accessing transit along SR 99, from 212th Street Southwest to Airport Road. (See Map)

We are seeking community input to help develop a priority list of improvements. While there is no funding to complete the improvements, prioritizing them will help identify which should occur first once funding is available. Implementing the full set of recommendations will require significant funding and partnership with jurisdictions and transit agencies.
