About
Lane closures (summer to fall 2025 and fall 2026)
I-84 will be reduced to one lane in each direction around-the-clock.
Crossover traffic (spring through summer 2026)
Eastbound traffic will share the westbound bridge for up to 5 months. During this time, I-84 will be reduced to one lane in each direction using the westbound bridge.
I-84 Closure (up to several days in 2026)
The interstate will be closed at the bridge for several days, which will require travelers to detour onto U.S. 26 from Biggs Junction to Portland. Details and dates will be announced in advance.
Historic Highway State Trail (spring through summer 2026)
The nearby Historic Columbia River Highway State Trail will also require a detour while construction is underway. During this time, there will be a two-month closure of the State Trail with shuttle service between John B. Yeon and Toothrock Trailheads.
How did we determine detours are the minimum necessary to complete construction?
We evaluated six construction options. All required months of traffic impacts on I-84 and the Historic Highway State Trail. Ultimately, we selected the option that offered the lowest construction risk, highest durability, fewer traffic and trail impacts, and lower cost.
Crews, cranes and other construction equipment will need a large work area to remove the existing bridge and construct the new bridge. Both directions of traffic will share the westbound bridge for nearly six months while crews work to remove and rebuild the eastbound bridge. A closure of the interstate will be needed for several days in 2026 to safely hoist the new bridge into place.
Location
I-84
|
Eastbound near Warrendale.
Cost and Funding
Project cost: $31.4 million
Benefits
The existing eastbound bridge is aging and in poor condition with ruts and bumps. There are also limited routes available to efficiently travel around the bridge if it were ever damaged during an earthquake. The new bridge will meet current design standards, which will increase the lifespan of the highway and protect public safety by allowing it to better withstand an earthquake.
Additional Information
Over the next several years, we have many construction projects planned on I-84 between I-205 and Hood River, and on the Historic Columbia River Highway between Troutdale and Hood River.
