SEATTLE (AP) -- Port of Seattle commissioners approved $268 million Tuesday for the Alaskan Way Viaduct replacement program. The port agreed with the state Transportation Department three years ago to contribute to the $3.1 billion project to replace the viaduct with tunnel.
Tunneling by the world's largest boring machine began last week.
Port and transportation officials believe the tunnel and surface road improvements will help keep freight traffic moving along the Seattle waterfront.
The port's contribution will come from the sale of bonds which will be repaid by taxes on property owners in the port district.
