The Transit Tunnel is a railroad tunnel located in the east of the desert, next to the Boomslang Overpass. It was originally introduced on April 25, 2016 as part of the timed quest called Refining Oil.[1]

A total of 5 assets are needed to complete construction of Transit Tunnel. This is equivalent to 5 Megabucks sm if one were to buy every asset instead of waiting to receive them from neighbors.
