PORTLAND, Ore. -- The Oregon Department of Transportation held the second of six meetings on Thursday to talk about the possibility of tolls to ease congestion on I-5 and I-205.

The two routes ODOT is considering for tolls: I-5 and I-205 from the Washington border, down to the I-205 junction south of Portland.

The meeting was held by a special committee. For the first time they unveiled different possible concepts for tolls, or what they call "value pricing".

One option is tolling all lanes. Another, tolling one existing lane. And yet another: Build a brand new lane, and tolling that lane.

Officials say they haven't reached a point where they could talk about how much tolls could cost, and say it would be years before they are put in place, if tolls get the green light.

Public comment is accepted at meetings.

Here are the next ones:

Meeting 3 – Feb. 28, Wednesday 2 - 5 p.m.

Meeting 4 - April 11, Wednesday, 1:30 - 4 p.m.

Meeting 5 – May 14, Monday 10 a.m. – noon

Meeting 6 – June 8, Friday, 10 a.m. - noon.
