(1) Before entering into any contract for the construction of or replacement of any bridge, excluding bridges that are replacing culverts that are barriers to fish passage, the secretary, or a designated employee, must consider whether to require the installation of informational signs that address the hazards of diving or jumping off the bridge as part of the contract. These signs are meant to provide more information than just a "no jumping" sign so that people can better understand the hazards related to a particular location. Signs with information on the hazards of cold-water shock that leads to drowning are encouraged to be installed in locations where people might otherwise think a location is safe for swimming. Signs under this section may include the statewide 988 suicide prevention hotline.
(2) Signs created under this section for placement within the right-of-way of the state highway system may not conflict with provisions of the manual on uniform traffic control devices or existing state laws related to placement and design of signs that are placed along transportation corridors.
(3) This section does not create a private right of action by, or a legal duty to, any party, and may not be used to impose liability on the department if a sign has or has not been erected on its property. The state of Washington, including all of its agencies, subdivisions, employees, and agents, shall not be liable in tort for any violation of chapter 54, Laws of 2023, notwithstanding any other provision of law.
