Guy F. Atkinson Construction is working on a $121.4 million tunnel system that will house a 2,000 foot long light rail under downtown Bellevue, Washington.
Unlike the Seattle tunnel currently underway, the Bellevue tunnel will not be dug by boring machines. These are said to be the largest tunnels excavated by the Sequential Excavation Method (SEM) in the United States to date. A method used to minimize the risk of ground loss and reduce the impact on neighboring homes and businesses
Eco-Pan is on-site assisting with concrete washout pans and service until the project is complete, which is estimated to open around 2023.
