WSDOT I-405, I-5, SR 520, SR 92 Project

In Spring 2022, our Monroe Division began working with WSDOT to make major improvements along sections of I-405, I-5, SR 520, and SR 92 in King and Snohomish counties. Our crews have worked to pave and repair various portions of the roads and bridge decks, replace expansion joints and traffic loops, install traffic systems, temporarily control erosion, and provide temporary traffic control among other work. Short working windows and complex logistics added challenges to the project. The crews worked over 100 days in 2022 to lay 26,000 tons of asphalt and complete other work. Because of weather, the project was winterized but will continue in 2023.
