The Saga of Crater Tunnel

Actually, this might be better described as the saga of crater that use to interrupt a tunnel.  If you haven't seen them yes, you can check out the galleries of exploring the tunnel before seeing/reading about the fate of the crater itself.
5/30/04: Our first expedition
This was from our first trip to the tunnel.  This is the best picture I have to give a sense of scale the those images that follow.

At this point in time, there was no indication that this would be filled in.  There was no landfill or construction materials outside of the crater.

7/25/04: Preparing for Construction
Here's a look from a nearby overpass down into the crater at the downstream tunnel.

To the left is the mud they used to fill the crater.

Where there were once only steep walls, in the center of this picture you can see an angled "road" to get to the bottom of the cratter.

Note the bundles of bricks to the right of the frame.

8/29/04: Still green
This shot contrasts with the next one. 

Otherwise, there was little additional construction that I could see in this area.

3/12/05: Progress

The walls have now been cemented down on this side. 

Also, note that there is no water entering the downstream tunnel... left via this black plastic culvert just outside one of the two tunnels entering the crater. 

I honestly have no idea where the water went, though there was a blue pipe that can be seen in the image above.

Unfortunately, I didn't actually explore any of the tunnels during these trips.

4/20/05: Contruction is underway
I missed out of photographing some of the major changes.  By the time I returned, the tunnel was completely covered over with this new section.

Here's a close-up.  You can see that additional feeder tubes were to be added.

Dani and I took a trip through the tunnel to see what it looked like from the inside at this point.  That gallery is here.

5/1/05: Ever shallower...
By now the crater is almost completely filled, but this submerged shaft continues to grow.

Here's a close-up.

And here's Dani on the overpass.  (Yeah, it's completely unnecessary, but I'm going to throw this one in anyway.)
