Seattle Tunnel Partners (STP) is a joint venture between Dragados USA and Tutor Perini Corporation, two top-tier construction firms whose portfolios include large public works projects throughout the U.S. and worldwide. STP is building the State Route 99 Tunnel – two miles long and 58 feet in diameter – under downtown Seattle so that the Washington State Department of Transportation (WSDOT) can demolish the earthquake-damaged Alaskan Way Viaduct.
