Moving Lines For Station Construction, Providing Power To The Tunnel Boring Machine
Building the Roosevelt Station and powering the machine to drill the tunnel to the Maple Leaf Portal is a little like planting a garden. Much as the soil must be worked ahead of planting seeds, electrical relocations need to take place before anything else happens.
Here is an approximate timeline. See the maps on the right.
