Tolling at the Washington-Oregon state line is tentatively on hold.

The 25-member Value Pricing Policy Advisory Committee held its penultimate meeting Monday to narrow tolling concepts Oregon is considering, as directed by the Oregon Legislature as part of a $5.3 billion transportation plan.

The favorite concept is tolling all lanes on Interstate 5 between Multnomah Boulevard and North Going Street. But that doesn’t mean tolling all lanes on I-5 and Interstate 205 from south of Marine Drive to the merging point of both freeways is off the table.

“‘Not yet’ is the phrase I would use,” said David Ungemah, WSP’s managed lanes and roadways service area manager. WSP is the contracted engineering firm consulting with the committee.

The committee evaluated five concepts, A through E, but appears to be leaning toward Concept B, the plan recommended by WSP that would use tolling on just I-5 as a pilot project. If the project is successful, the consultants say Oregon could then consider Concept C, expanding tolling to all lanes of I-5 and I-205.

Concept C would provide the most congestion relief. But it’s also complex to implement, said Chris Swensen, southeast director for toll systems and managed lanes for WSP.
