Demolition timelapse from a Western Avenue office building:

I love videos like this.

I especially liked the chomper thing that seemed to chew away the concrete vaguely like the Cookie Monster. What I wasn't expecting though is just how much of the process of demolition consists of hauling the stuff away. I'm amazed too that at one point in time all that concrete and rebar had to have been hauled in. The significant visual transformation of the area due to the demolition makes a bit more sense to me now given just how much material was there.

On a side note, I've been to Elliott's Oyster House on Pier 56, and so I've probably walked under the viaduct right where the camera was.

I must admit, I think it was cool to see two weeks of demolition and clearance work squeezed into a 15-minute video.

Tolling is delayed until fall due to missed deadlines from the tolling vendor.

Is there a concession to the vendor, or is the state expecting to see toll revenue from this?

I loved the video.  It reminded me of a bad stop-action monster movie.   :bigass:

Small trinkets made out of viaduct rubble sell for $150-200. I wonder if WSDOT actually authorized this.

So where are they disposing of all that steel?  I'm assuming the concrete is being crushed and recycled.

I would assume that all of that rebar steel is being cut into manageable-sized pieces to be sold and delivered by truck and/or rail to whatever scrap yards are offering the best prices for it, to in turn be sold and delivered to whatever foundries and/or steel mills are offering the best prices for it.  Scrap is a very important raw material for foundries and steel mills and yes, iron and steel has always been one of the very most 'recycled' materials of all.

A couple weeks ago, I was driving south on 99, and exited at Harrison. I couldn't help but notice, after proceeding straight towards downtown (on Aurora Ave), that the entrance to the Battery St Tunnel has completely disappeared. As far as I could tell, they were preparing the roadway for its final configuration. I proceeded straight down the middle of Aurora all the way to Denny, when traffic normally would have swung right to avoid entering the tunnel.

I appreciate your sharing this video! It gives me a better understanding of what goes on in the demolition process, from the dismantling of the bridge decks to the removal and transport of the resulting debris (most of which is recyclable).

This was the view from Denny Way about a month ago:

GSV from that area is from May, and shows them doing some of the fill-in work.

They said take a left at the fork in the road.  I didn't think they literally meant a fork, until plain as day, there was a fork sticking out of the road at a junction.

A few shots of the waterfront from this morning:





The new pedestrian bridge to the ferry terminal was built as soon as a section of the viaduct was removed, but the building it goes to isn't completed yet.  The section of Viaduct around the existing ped bridge probably won't be demolished until the new bridge is ready.  For all the delays that the tunnel had, how would they have handled the new ped bridge if the viaduct had been demolished years ago?  That is, a new southerly ped bridge wouldn't have connected to anything until the new terminal building was built.

It could have been connected to a section of the existing balcony next to the (now removed) clock enclosure. Or, more likely, they'd have demolished the old bridge anyway and just run shuttle buses between 1st and the street-level entrance for ADA compliance while telling everyone else to just hoof it uphill.

The last double-decker section (at the pedestrian bridge) is about to come down.

Managed to grab one last shot of that underpass on the 19th of August. Also grabbed a shot of the Temp-90 sign, but I won't post it since it's been posted to death already.

Apparently my brother was at the site when the local news was interviewing pedestrians about the change.  Who knew he was decent on camera?  He's the first and last person interviewed in the segment.

Ha! Nice! Roadgeekery runs in the family, whether you like it or not. Was he intentionally trying to get interviewed? Was he down there specifically to see the viaduct?

Nope, not intentional.  Just walks most places around Seattle unless he needs to work.  He drives to work, but other than that, has to leave town to enjoy his vehicles and motorcycles.  His condo is about 4 blocks south of the Needle within sight of the monorail, so he's convenient to a great many places by foot and just happened upon the crew.  I don't even know if he's aware of my geekery actually.  If he lived anywhere other than Seattle, he probably might be one himself.  Traffic there just sucks the joy out of driving most days for him.  He's got a buddy that has land out east closer to the mountains, so he's likely to pick up a small camper to pull behind the 1996 4Runner he just picked up and spend more time out of town, though.

It does and when they parkify it further, it will look even better.  I will miss the views we got from driving north on it, especially at certain times of the evening in the clearer summer months, but this is progress and for the better.
