Washington Revised Code Title 53. Port Districts § 53.34.010. Toll bridges, tunnels authorized--Highway approaches--Tolls proposed

(1) Toll bridges;

(2) Tunnels under or upon the beds of any river, stream, or other body of water, or through mountain ranges.

In connection with the acquisition or construction of any one or more of such projects the port districts may, with the consent of the state department of transportation, further acquire or construct, maintain, operate, or improve limited or unlimited access highway approaches of such length as the commission of such district deems advisable to provide means of interconnection of the facilities with public highways and of ingress and egress to any such project, including plazas and toll booths, and to construct and maintain under, along, over, or across any such project telephone, telegraph, or electric transmission wires and cables, fuel lines, gas transmission lines or mains, water transmission lines or mains, and other mechanical equipment not inconsistent with the appropriate use of the project, all for the purpose of obtaining revenues for the payment of the cost of the project.

Consistent with RCW 47.56.850, any toll, including any change in an existing toll rate, proposed under this section must first be reviewed and approved by the tolling authority designated in RCW 47.56.850 if the toll, or change in toll rate, would have a significant impact, as determined by the tolling authority, on the operation of any state facility.
