(1) The Puget Sound council of governments (until July 1, 1975, known as the Puget Sound governmental conference) now engaged in a study of the withdrawal from the interstate system of that segment of state route No. 90 between the south Bellevue interchange and the Connecticut street interchange on state route No. 5 and the substitution of public mass transit projects in lieu thereof as authorized by section 103(e)(4) of Title 23, United States Code, is directed to complete all phases of the study by November 1, 1975.

(2) No later than January 15, 1976, the city councils of Seattle, Mercer Island and Bellevue and the county council of King County shall each by resolution either approve or disapprove a request to withdraw from the interstate system the segment of state route No. 90 between south Bellevue interchange and the Connecticut street interchange on state route No. 5. Nothing in this subsection shall be construed as requiring the city or county councils to adopt by January 15, 1976 any proposal for substitute mass transit projects.

(3) If at least three of the four city and county councils request withdrawal from the interstate system of the designated segment of state route No. 90 by January 15, 1976, and such request is thereafter concurred in by the governor and the Puget Sound council of governments, such determination shall be final as it relates to the state of Washington and except as may be required to terminate the project in an orderly manner, no moneys shall thereafter be expended from the motor vehicle fund for further development of the designated section of highway as an interstate highway without further express authorization of the legislature.

(4) If fewer than three of the four city and county councils request withdrawal from the interstate system of the designated segment of state route No. 90 by January 15, 1976, or if the governor does not concur in the withdrawal request, then no tax revenues collected by the state of Washington shall thereafter be expended for the construction of substitute public mass transit projects in the Seattle metropolitan area pursuant to section 103(e)(4) of Title 23, United States Code, without further express authorization of the legislature.
