I-5 Toll Project


We have a congestion problem through central Portland.

I-5 carries the highest number of vehicles and freight in the region. As traffic congestion increases, trips take longer and are less predictable, which impacts our quality of life and the regional economy.

From 2015 through 2017, the number of congested hours each day increased by 13% on freeways in the Portland metro region. And it’s getting worse. The 2018 Traffic Performance Report estimates by 2040 there will be a 35% increase in population and 1.8 million more vehicular trips per weekday traveling in or through the region.

Tolls are one tool among many ODOT is considering to improve our transportation system.

This project will consider tolls on all lanes of I-5 through central Portland, a seven-mile stretch of road (tolling extents to be determined). This includes the most congested segments of I-5 through Portland.

The goal is to reduce congestion and provide a more reliable trip by encouraging drivers to consider other travel options or times of travel. If a small percentage of highway users choose another mode of travel or time of travel, traffic congestion is reduced for those who can’t modify their trip.

Current Status: Alternatives Analysis

Start and end points for tolls along this corridor will be defined as part of the technical and environmental analysis. This will include:

A map shows that all lanes on I-5 through central Portland would be priced and the endpoints of the toll will be evaluated.

  • An evaluation of options and end points of the tolled area
  • An assessment of the potential for diversion onto the surrounding street system, including Barbur Boulevard (OR 99W) in SW Portland, Martin Luther King Jr. Boulevard in NE Portland and other streets
  • An evaluation of existing transit service to accommodate new riders
  • An evaluation of parking capacity at area park and rides
  • Consideration of equity and mobility strategies to ensure all demographics receive travel benefits

ODOT is planning extensive public and stakeholder involvement to inform an equity framework, project development and community mobility and equity priorities. 

Multiple strategies are planned to ensure the Oregon Transportation Commission and ODOT staff hear a diversity of perspectives before decision-making on selected alternatives for both I-205 and I-5, equity and mobility strategies and, in the future, toll policies and rates. 

Planned strategies include: 
  • Advisory Committee
  • Equitable and focused engagement with people who have been historically marginalized and who have low incomes
  • Broad public and community engagement with both in-person events and online tools
  • Briefings to and collaboration with existing regional policy groups (e.g. Joint Policy Advisory Committee on Transportation, Region 1 Area Commission on Transportation)
  • Technical work groups made up of regional staff to review methodologies and analytical results that incorporate stakeholder input


The process to implement a toll program requires substantial analysis, public input, construction, testing and driver education before the system can be operational.
