With the new tunnel open under Seattle, the process of getting rid of the Alaska Way Viaduct is underway.  Large sections have already gone and others are in the process of being taken own.  From the viewing terrace at Pike Place Market, you can get a good view of the demolition at the moment.  The sections that have gone are replaced with a space full of dust and rubble.  Meanwhile, heavy machinery is in the process of drilling out the viaduct deck and the barriers.  There is more to come on this one.
