The digging on the second half of the bus tunnel is underway. The excavation work will go through the end of this month and you can see the pile of dirt getting bigger by the day. Once the excavating is finished, the concrete work will begin on the substructures and walls. In another few months the second half will be connected to the first half of the tunnel already completed.
