Success for this endeavor prevailed from a commitment to a shared vision of the future and a set of guiding principles to measure against. Such a strategy identified which characteristics were most important to allow for a multimodal vision to align investments. This required robust technical analysis along with clear communication about the benefits of the multimodal set of improvement projects. From this launchpad, the I-405 executive committee, city council members, technical committee members, staff from 30+ jurisdictions, four transit agencies, numerous community-based organizations, environmental and tribal groups, worked together to share the vision and implement key parts of the master plan.
This influential coalition enabled a stream of necessary funding for implementation. Perhaps the best vote of confidence can be measured in dollars invested. To date, more than $4 billion has been invested or is targeted for investment in corridor improvements, starting with the Nickel Transportation Investment Package in 2003, the Transportation Partnership Program in 2005, the Connecting Washington Package in 2016 (a portion of the Sound Transit 3 transit program), and most recently, the Move Ahead Washington Package in 2022.
