Underwater Tunnel Sections Initial

The Underwater Tunnel Sections are pieces of roads and railroads is (define type) connecting with Archipelago and later as part of ring road around Megapolis Mainland. It was originally introduced on August 21, 2015 as part of the timed quest called Oceanic Trench.[1]

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

At the point where road and rail pieces cross their ways this special section appeares:
