Washington Governor Jay Inslee (D) December 16 unveiled a $12 billion state transportation funding plan. The 12-year proposal would be funded through a combination of bonds, fees, and a new carbon tax. It is estimated that the tax alone will generate $400 million per year. Supporters say the plan would create 50,000 jobs throughout the state and provide $5.9 billion in new construction.

The proposal will be put before the state legislature for consideration when lawmakers convene in January 2015.
