Bui 4

Big Bertha , Underground Tunnel Highway , Seattle.  This construction intrigued me because of the vast and complex process. The process of drilling massive amount of dirt and stones beneath the earth requires a gigantic drill-bit system and architecture.  With so many moving parts in symmetry working in conjunctions as a whole is such a fascinated structure.  The project is currently at a stand-still ( drill system (bertha ran through some huge boulders and rock, assumption, was overheated.) but you can see from the diagram and incomplete model of how it well it could work.  It will eliminate heavy congested traffic.
