With the Ramps Gone, How Does the Heavy Equipment Make it in and Out of the Pit?

On March 6, 2017, work began to excavate the ramp that served as the “road” to the bottom of the pit. Early on in the construction
process, there was no need for a ramp. As the pit got deeper a ramp was required and over time the dirt ramp had to be moved three times.
Even while the ramp was operational two cranes were used to transport the rebar from the trucks to the floor of the pit.
