I-84: Snow Zone Safety Improvements (Pendleton-La Grande)

Project Completed

Region 5: Eastern Oregon (La Grande, Pendleton, Umatilla, Union)

​​​​We will construct a variety of enhancements along Interstate-84 between Pendleton and La Grande to improve safety and operations during adverse winter weather conditions. 


Traffic Impact

​Expect lane closures and reduced speeds at various work sites, with some congestion and delays. Rolling slowdowns may also occur at times.

Meetings and Events

In 2016 we worked with key freeway users (trucking, emergency responders, local cities/counties, motorists, etc.) to develop an Interstate Corridor Safety Plan for eastern Oregon. This I-84 Snow Zone Safety Improvement Project was developed out of that planning effort and includes several enhancements idetnified in the plan. The corridor plan, this and other area projects were then featured in an online open house held in 2018. 

Key Milestones

The project is complete. We've heard from truckers and other drivers that improvements are making a big difference.


​Construction is taking place in 2019 and 2020.



​We constructed the following key project elements:
• Over a dozen new variable message signs through the corridor (Pendleton- La Grande).
• 10 road/weather sensors through the corridor.
• A dozen curve warning signs with flashing beacons in the Grande Ronde River Canyon area.
• Nine miles of cable barrier between EB and WB lanes at two locations to prevent cross over crashes (MP 229.2-237.6 and MP 249.20 to MP 250.16).
• Prep work for new LED lighting at Cabbage Hill WB curve (MP 220.9 – 222.7).
• New camera (WB MP 247.4), snow zone sign (EB MP 220.6), and ramp gate (WB Exit 224).
• New yellow reflective markers attached to guardrail in Cabbage Hill area.
• Several miles of buried power line to support these and future enhancements.  ​

Cost and Funding

​The project is $15.6 million, with $4 million allocated from the 2017 Keep Oregon Moving Transportation Bill. 

What Problem Will This Improve?

Severe winters, snow, ice, fog and high truck traffic make this freeway section one of the most challenging in eastern Oregon. The area is remote and lacks power for signs, sensors and other enhancements. The power cables installed will support the new signs, sensors and other improvements in this project, plus future safety enhancements. While behind the wheel, these features will advise of conditions ahead, so you can adjust your driving. The new cameras and weather data shown on will help you make informed travel decisions before you get on the road.
