Viaduct removal is done in three stages, the WSDOT said in a Tuesday blog post. First, the area of the elevated roadway needs to be prepared, then the road is demolished. Finally, the work zone needs to be cleared and restored.
Restoring the roadway includes such tasks as removing the "crush pad" placed on the ground before demolition to protect the street and utilities beneath it, as well as filling in the foundations that once supported the viaduct.

Once the roadway is clear, it's repaved and re-striped before it is re-opened to pedestrians and parking.
Crews had demolished half of the viaduct and remained on-track to finish most of the demolition this summer. Within the next two weeks, crews were expected to head south from King Street toward Pioneer Square.
