OOOHHH! Have I got a scoop ahead of TunnelTalk! This is proof that the development in bankrupt Dubai was a little bit crazy!
A Roads and Transport Authority (RTA) official said they weren't aware of the tunnel which links Downtown Burj Khalifa to Al Mafraq Road and bypasses heavy Dubai Mall traffic congestion on Financial Centre Road (formerly Doha Road).
They have a perfectly good road tunnel that nobody knows about! This is much better than having a non-tunnel (Niagara) that everybody knows about, but nobody says anything!
