Columbia Gorge Projects


Columbia River Gorge Construction

I-84 & U.S. 30 (Historic Columbia River Highway) 

Upcoming projects between I-205 and Hood River


The Columbia River Gorge is one of Oregon’s seven wonders – home to the first highway in the Pacific Northwest, sweeping vistas and rich history. And for more than 100 years, it’s been an important corridor for freight movements, both in the water and on the road.

Over the next several years, we have many construction projects planned on Interstate 84 between Interstate 205 and Hood River, and on the Historic Columbia River Highway between Troutdale and Hood River. 

Each project brings benefits to residents, businesses and visitors by increasing safety, extending the lifespan of the highways or completing a gap in walking and biking infrastructure. 

Learn more about each project below.

Construcción en la garganta del río Columbia

La garganta del río Columbia es una de las siete maravillas de Oregón: además de la primera carretera en el Pacífico Noroeste, tiene maravillosos paisajes y una rica historia. Y durante más de 100 años, ha sido un corredor importante para movimientos de carga, tanto en el agua como en la carretera.

Para los próximos años, tenemos muchos proyectos de construcción planeados en la Interstate 84 entre la Interstate 205 y el río Hood, y en la Carretera Histórica del Río Columbia entre Troutdale y el río Hood. Ver información en español

Other projects

A Better Red

TriMet is constructing a new bridge over I-84 at Gateway as part of its Better Red Project. Travelers may encounter shoulder closures on I-84 and I-205, and nighttime lane closures on I-84; full closures of I-84 east Exit 7; and several full weekend closures of I-84 at I-205. 

Schedule: Construction began in 2021 and continues through 2024. 

What is the Historic Columbia River Highway?

The Historic Columbia River Highway was constructed between 1913 and 1922. In the early 1950s, many miles were damaged or destroyed to pave the way for I-84. Currently, an effort is underway to restore all 73 miles of the highway from Troutdale to The Dalles. Some segments, known as the Historic Highway State Trail, will be accessible only by people walking, rolling or biking.  We are so close to completing the restoration of all 73 miles. Two projects are underway, with the last 1.6 mile segment scheduled to begin construction when funding is secured.
