Additional Information

​This project is a partnership between ODOT, the U.S. Forest Service, Oregon State Parks and Recreation Department, Multnomah County and the Federal Highway Administration. 

The project builds off several successful efforts to manage congestion and improve safety in the Waterfall Corridor, continuing the essential collaboration between these agencies to identify and achieve solutions for the Gorge. Some of these efforts include:
In addition to the project partner agencies, numerous stakeholders will be involved in plan development, including Federally recognized Tribes, residents, visitors, the Columbia River Gorge Commission, elected officials, emergency responders, cyclists, local businesses, hikers and other recreationalists and advocacy organizations. 

How to be involved 
The project team is committed to hearing from people who love the Gorge to identify key concerns and ideas, to ensure the solutions developed reflect public input and aspirations. The project team will be working with stakeholders and the community throughout the planning process to seek input and feedback as the plan is being drafted.
