Budget

The state’s viaduct replacement projects are estimated to cost $3.3 billion. Funding comes from state, federal and local sources, as well as the Port of Seattle and tolls.

May 2019 update: In the 2017-19 budget, we requested additional funding to deliver the remaining program work. $59 million of this request was approved by the legislature in the 2017 budget, and another $54 million in the 2018 supplemental budget.  $35 million was approved with the 2019 legislative budget.
