This project is the third of four projects that will widen US 12 from two to four lanes from SR 124 to Wallula. This particular project widened and added lanes from Dodd Road to the vicinity of Boise Cascade's paper mill. WSDOT also improved safety by consolidating access within the project limits to two channelized intersections. Construction of the four-lane divided highway will reduce congestion and intersection related accidents. The average daily traffic on this route ranges from 7,000 to 13,000 vehicles. As many as 33% of the vehicles are heavy trucks. Over ten million tons of cargo travel this section of US 12 each year. Slow moving trucks and recreational vehicles impede the flow of traffic on this two-lane facility.
Providing a four-lane divided highway greatly enhanced safety for this corridor. Opposite direction traffic is now separated by a median or concrete barrier. Access to US 12 is limited to channelized intersections.
Widening this section of US 12 has reduces congestion. To learn more about WSDOT's congestion relief efforts visit the WSDOT Congestion Relief site.
| Protects Environment
WSDOT completed an environmental assessment for the SR 124 to Wallula corridor to identify the potential impacts to the natural and human communities. Several strong partnerships were developed with state and federal agencies in order to address the substantial environmental challenges of this corridor improvement project.
