Because the First Avenue South Bridge in Seattle is a part of the state highway system, and not a county road, RCW 36.83.010 does not authorize King County to form a service district as a financing tool for improvements and/or new construction relating to that specific bridge.
Counties may not jointly construct and finance a bridge to be located entirely within the territorial boundary of one county.
The City of Seattle, the State Highway Commission, King County, the Port of Seattle, and, to a limited extent, the Municipality of Metropolitan Seattle (Metro) may form a joint venture under the interlocal cooperation act (chapter 39.34 RCW) for the construction of an improved West Seattle bridge.
(1) The vacation of a ferry service by a board of county commissioners constitutes, and is subject to the same provisions governing, the vacation of a county road or bridge; however, if existing ferry service has been discontinued because the system has been destroyed or partially destroyed, the decision of the board of county commissioners, exercising its discretion, not to repair, reconstruct or re‑establish [[reestablish]] ferry service is not under existing law subject to any procedural requirements. (2) There is no obligation on the part of the highway department or county road departments to plow out or remove snow deposited on entrances to private driveways or roads, within the public highway rights of way, during the plowing of county roads or state highways, provided that access rights have not been taken thereby.
The county is obliged to repair and maintain all bridges, by whomsoever constructed, which lie on the right of way of an established county road. Such obligation does not extend, however, to public roads within the county, which have not been duly established as county roads by resolution of the board of county commissioners, or which have not been made part of the system of county roads by operation of law.
