The EPBM built by Hitachi Zosen for Seattle Tunnel Partners is the largest ever TBM built and will build the largest ever TBM bored tunnel as the central part of the WSDOT (Washington State Department of Transportation) project to replace the elevated Alaskan Way viaduct across the waterfront of Seattle.
