November 30, 2005: Multiprocessing again - with Bob McCabe's group playing the Pearman, Pio's group playing the Grace and Mickey's group playing D-25. In the background you can see Brad's shear yawning a bit.

Another view with Ted playing his concrete cutter over the 3th vertical support

Brad moves in with his grapple and starts picking up half-roadway segments

then rotates and puts it to sleep behind him

When a section is removed, Ted moves back in with his concrete cutter - just barely visible to the left of the grapple

Now its Richie's turn. While Brad stabilizes the guard rail, Richie cuts the next segment to be removed.

Once the guardrail is removed - Brad starts the next iteration of removing chunks of roadway -

rotates and puts it down

and when finished Ted moves in and starts cutting the next matrix

Here is a last view that shows all the instruments: Ted playing his cutter, Brad making a yawn with his grapple, probably Richie in the micro-CAT, Ted's truck (that provides the water for cooling, and I suppose lubricating the diamond saw blade) and Pio - somewhere.

It is just about time for Mickey's team to drop D-25 - so work stops and everyone becomes a cheerleader
