"Build the Stone Tunnel Entrance so drivers can get past the Mountain Ridge."
"Build the Stone Tunnel Exit so drivers can get where they need to go even faster."

The Stone Tunnel is a road tunnel that runs through a hill south-east of Overpass expansion zone. It was originally introduced on September 25, 2015 as part of the timed quest called Ring Road.[1]

A total of 110 assets and additional 500,000 Coin sm.png worth diagrams are needed to complete construction of both parts of Stone Tunnel. This is equivalent to 110 Megabucks sm.png if one were to buy every asset instead of waiting to receive them from neighbors.
