On October 4, 2018, onlookers watched as a 3.8 m (12.5 ft) diameter Robbins Main Beam TBM completed its epic journey. The TBM, christened "Driller Mike", after local rapper and activist "Killer Mike", overcame extremely hard rock conditions along a curving 8.0 km (5.0 mi) tunnel to bolster the city of Atlanta, Georgia, USA's water supply.
