Funding and Tolling
Funding for the total Puget Sound Gateway Program will come from the state gas tax, tolls, local contributions and potential federal grants. Total funding for the project is $1.87 billion, and local contributions will be $130 million. WSDOT is also seeking a federal grant.
The Washington State Legislature intends $180 million from tolls to be used for the SR 167 and SR 509 Completion Projects. A toll authorization bill must still be passed by the Legislature before tolling begins. The SR 509 extension will have one toll point on all new lanes. Toll costs are set to increase during weekday rush hours. The price will not change based on traffic flow.
