Washington Revised Code Title 81. Transportation § 81.53.240. Scope of chapter

(1) Except to the extent necessary to permit participation by first-class cities in the grade crossing protective fund, when an election to participate is made as provided in RCW 81.53.261 through 81.53.291, or to the extent a first-class city requests to participate in the commission's crossing safety inspection program within the city, this chapter is not operative within the limits of first-class cities, and does not apply to street railway lines operating on or across any street, alley, or other public place within the limits of any city, except that a streetcar line outside of cities of the first class shall not cross a railroad at grade without express authority from the commission. The commission may not change the location of a state highway without the approval of the secretary of transportation, or the location of any crossing thereon adopted or approved by the department of transportation, or grant a railroad authority to cross a state highway at grade without the consent of the secretary of transportation.

Within thirty days of modifying, closing, or opening a grade crossing within the limits of a first-class city, the city must notify the commission in writing of the action taken, identifying the crossing by United States department of transportation number.
