The Columbia Gorge Express is a pilot program developed by ODOT with the US Forest Service, TriMet, Travel Oregon, Oregon State Parks and other agencies to reduce traffic on Interstate 84 and parking congestion at Mulltnomah Falls - Oregons number one natural attraction.
The Columbia Gorge Express mobile application makes it easy to book tickets, track (in real-time) where each shuttle is along the route, and plan your trip accordingly based on real-time shuttle capacity.
Continued use of GPS running in the background can dramatically decrease battery life.
