Financial statements

I-405 tolls are accounted for in a separate account within the state treasury that is dedicated to the I-405 program. All spending is appropriated by the Legislature and monitored by the Office of Financial Management. Toll rates are set by the Transportation Commission. Interest is accrued on toll revenue and the interest that accrues is dedicated to the I-405 account. All toll revenue and interest earnings in the I-405 account go toward paying ongoing operating and maintenance costs. Any revenue generated beyond operating costs will go in a dedicated account for I-405 and will be reinvested in the corridor. RCW 47.56.884 includes more information.
