Oregon’s Transportation Commission unanimously approved a plan to toll sections of Interstate 5 and 205 in the Portland area yesterday. The Portland Oregonian reports an application now heads to the Federal Highway Administration for consideration. They hope to hear from highway officials early next year. A consultant could be hired in April to start working in more detail on the issue. The money would be used for road projects and manage traffic. An official said the Portland area is expected to add more that 500,000 new residents in the next 20 years, and tolling is just one thorny issue the state must confront as it tries to manage that growth.
