Contractors are starting work this week on a 2-year-long project to make massive changes at the Biggs Junction Interchange with Interstate 84 and Highway 9. This week the contractor will be installing temporary traffic control devises including concrete barriers. Traffic on I84 will be reduced to one lane in both EB and WB direction. Expect construction activity on shoulders throughout the project site. There may be short delays along US97. There will be no delays on I-84.
Work on the intersection is needed because of the heavy truck traffic circulating throughout the project area and the tight turns at the top of the off-ramps. Traffic studies indicate that if no improvements are made to these intersections, there will be vehicle back-ups down the entire length of the off-ramps and onto the mainline of I-84 in the foreseeable future. The $23 million project will widen the highway and bridges on U.S. 97 from two to five lanes near the I-84 interchange. Traffic signals will be installed at the ramp intersections, and at the intersection of U.S. 97 with the Celilo-Wasco Highway and the Biggs-Rufus Frontage Road in Biggs Junction.
