Plans are now in hand for a 2.7km tunnel in the US to be built in the city of Seattle in Washington State. The tunnel would carry Highway 999 along the Seattle waterfront. The tunnel would run at depths down to 61m. One of the proposals would see the tunnel opening in late 2015. The 914 Washington State Department of Transportation set a budget of US$1.09 billion for the work. The tunnel will be built by Spanish firm 917 ACS and will be able to carry 110,000 vehicles/day.
