THE CACHE
It is simple but fun to find cache close to one of the many tunnels that cross Sydney's underground's road network. To retrieve the cache from it's hiding location you will have to use a tool, so bring a bottle or something similar (you may find something helpful right under the begining of the bridge), and use your imagination. Coming along with a colleague will ease the find, but it won't be impossible if you come alone, you will just need to use your brain a bit more to be resourceful. Happy Hunting :)

THE CROSS CITY TUNNEL
The Cross City Tunnel is a 2.1 km-long twin-tunnel. It links Darling Harbour on the Western fringe of the CBD to Ruchcutter Bay in the Eastern Suburbs. The tunnel is actually two distinct tunnels and they largely follow a route underneath William Street and Park or Bathurst Streets, depending on whether it is eastbound or westbound.

It is privately owned and operated, but will revert to public ownership in 2035. The $680M tunnel was originally financed by a combination of international equity and both locally and internationally sourced debt.
There has been some controversy over the expected and actual usage of the tunnel during its initial operation. The number of vehicles travelling through the tunnel has been debated in the media, along with alleged discrepancies between the actual number of trips and the anticipated number of trips in the tunnel's financial projections.

Approximately one month after opening it was reported in the media that only 20,000 vehicles a day were using the tunnel, although the government and toll operators maintained that the average number of daily trips since opening was approximately 25,000.
The tunnel nowadays causes more criticism that admiration for the following reasons:
- Disruption to traffic in the CBD not using the tunnel
- Misleading signage
- Toll applies in both directions
- The hight Price of the toll
- No cash payment, and higher price for drivers without an E-Tag
- Concerns about exhaust fumes from the tunnel
