This massive 18-month removal project required careful, intricate planning and multiple pieces of equipment including a modified jack-and-slide, several cranes and a platform trailer equipped with 160 tires capable of carrying equipment weighing in excess of 500,000 pounds through a relatively narrow, 10 km long tunnel.
