The final mural is complete. We finished the setting and grouting on 10-27-11. Believe it or not we are 4 days ahead of skedule.  What a great project!! 
Now we wait till the bridge gets painted.  The painting is underway. it will be a bluish grey. The murals should really stand out.
The tenative date for the installation is the first week in December.  I will be there watching.
