The Oregon Transportation Commission voted Thursday to approve the state’s application to the federal government to consider a tolling program on Interstate 5 and Interstate 205 in Portland. The five-member commission voted unanimously to submit the application at their regular meeting in Salem. The proposed stretches of tolled roads would include Interstate 5 between Southwest Multnomah Boulevard and Northeast Going Street, a roughly 7-mile stretch through the heart of Portland, and Interstate 205 in and around the Abernethy Bridge around West Linn and Oregon City. The proposed tolling would also use variable toll rates, or value pricing, that would vary based on traffic or time of day.
