Finding—Intent—2012 c 83: "The legislature finds that there is an urgent need to replace the central waterfront section of state route number 99, known as the Alaskan Way viaduct, because the viaduct is vulnerable to closure, damage, or catastrophic failure as a result of earthquakes or other events. In 2009, the legislature determined that the finance plan for the Alaskan Way viaduct replacement project should include no more than four hundred million dollars in toll funding for the project.
Therefore, it is the intent of the legislature to authorize tolling on the Alaskan Way viaduct replacement project, both to help finance the Alaskan Way viaduct replacement project and to help maintain travel time, speed, and reliability on the portion of state route number 99 that would be replaced by this project."
