The tunnel would be the better safer in downtown Seattle because the another viaduct could fall down or break easy. I want downtown Seattle to looks nice.
If they build new viaduct, then it would look very ugly. The people who live in condos can see front of the water and boats. If they build another viaduct, then it could block and (they) can't see the water and boats. It is an good idea to have an new tunnel not another viaduct in downtown Seattle.
