I-82 links central Washington with eastern Oregon and feeds into I-90. The route is critical to the agricultural industry in the region and provides for the everyday movement of people from rural to urban areas.
Major projects recently completed or now under way on the I-82 corridor represent an aggregate budget for construction of approximately $42.7 million. With work on the projects in various stages of completion, the current estimate of the total final cost of construction for these projects is approximately 8% over budget at $46.2 million.

Beginning at the interchange with I-90, here are the major projects on I-82:
Yakima – Adding two new lanes on a one-mile segment of SR 24 from I-82 to Riverside Road to eliminate a serious bottleneck that backs up traffic onto I-82. Replaces bridges over I-82 and the Yakima River with wider structures, lengthens the ramps to and from I-82 at the SR 24/Nob Hill Boulevard interchange. Construction, started February 2005 and is scheduled for completion in early 2007. Estimated final construction costs are $41.3 million, approximately 12% over the project's construction budget of $36.9 million owing primarily to increased prices for steel, concrete and oil.

Union Gap – Installed durable pavement markings that are highly visible and retain reflectivity throughout the year to help reduce accidents along a 93-mile stretch of I-82 between Union Gap and the Oregon State line. Work started in September 2000 and was completed on schedule in July 2001. Low contractor bids and lower than estimated costs for lane striping are behind final project construction costs that were $1.2 million under the project's construction budget of $2.3 million.

Prosser - Built an eastbound weight station facility to serve this primary route for transporting agricultural products between the Tri-Cities and Yakima. The initial construction of the weight station ramps and connecting roads were completed at 9% over budget in 2004 at a construction cost of $3.5 million in relation to a construction budget of $3.2 million.
