Drivers could be paying a toll to drive on I-5 and I-205 in the next couple of years. The Oregon Department of Transportation is soliciting public comments now for an upcoming study on tolling those freeways. Aaron Golub is a professor in the Urban Studies and Planning department at Portland State University. He joins us to tell us more about what tolls on I-5 and I-205 might look like in the next few years, where tolling has worked elsewhere, and the challenges of addressing congestion along with safety and equity more broadly.
