A special session starts tomorrow in Olympia and Gov. Jay Inslee is pressuring the Washington State Legislature to pass a $10 billion transportation-tax package within a week as part of it. The primary aim of the session though is to get Boeing to build its new 777X in Washington.
That puts the transportation package on the back burner, meaning it may not happen this time. Few details are known about the prosed package to fund transportation at this point, except that it includes a 10.5-cent increase in the state gas tax phased in over 12 years and does not include funding for a new I-5 bridge over the Columbia River.
More info on the special session can be found in this Seattle Times article.
