Washington government operates on a fiscal biennium that begins July 1 of each odd-numbered year.  Biennial budgets are typically enacted in odd-numbered years for the upcoming fiscal biennium.  Supplemental changes to the biennial budget are typically enacted in each of the following two years.  Transportation packages are periodically adopted by the Legislature to provide resources for and identify a multi-year list of statewide projects and spending priorities.  Recent transportation packages include:  the Connecting Washington Package (2015); the Transportation Partnership Package (2005); and the Nickel Package (2003).

The bill authorizes a total of $1.3 billion in additive transportation spending for the 2021-23 fiscal biennium for purposes associated with the Move Ahead WA transportation package.  It requires the Washington State Transportation Commission to conduct a study of toll revenue performance on the Interstate 405/State Route 167 corridor focused on the sufficiency of revenues to pay for debt service and improvements to the corridor.
