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.

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

A Better Red

TriMet is constructing a new bridge over I-84 at Gateway as part of its Better Red Project. In 2021, expect shoulder closures and nighttime lane closures on I-84 and shoulder closures on I-205 north, and full closures of I-84 eastbound Exit 7. In subsequent years, expect additional lane closures and full closures of I-84 and additional closures of I-84 eastbound Exit 7. 

Schedule: Construction occurs in 2021 to 2023. 

What is the Historic Columbia River Highway?

Constructed between 1913 and 1922, the Historic Columbia River Highway overcame all odds. At the turn of the century, after visiting Europe’s great roads, two men had a vision to create an even better road here in the United States designed exclusively for this new contraption called the automobile. This road would lay lightly on the land and take its users to the most beautiful spots and breathtaking vistas of the Columbia River Gorge.

In the early 1950s, many miles of the Historic Columbia River Highway were damaged or destroyed to pave the way for Interstate 84. The passage of the Columbia River Gorge National Scenic Area Act in 1986 motivated the Oregon State Legislature to commit to restore the entire Historic Highway to its glory days of the 1920s.

Currently, an effort is underway to restore all 73 miles of the Historic Columbia River Highway from Troutdale to The Dalles. Some segments are accessible to cars and cyclists, such as near Multnomah Falls. 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. One project is underway now, with another scheduled to begin construction in 2022.
