A giant roadheader, which was built in Northeastern Germany, was shipped to Oakland and assembled at the east portal of the Caldecott Tunnel. There are several weeks worth of work that must happen before the excavation can begin. According to Caldecott-tunnel.org, the $3.5 million dollar machine weighs 130 tons and has been attended to by several German workers who arrived with the machine to oversee its assembly and testing.
