Yesterday we went to the Clem7 Opening day. I had booked tickets 2 weeks ago, and tickets were fully booked. We got there and they didn't even look at tickets (or check bags like they were supposed to.)
We walked into the tunnel to the deepest part, 60metres below the Brisbane River. There were heaps of people standing around at the deepest part taking photos of the signs. That was about the only time I felt a bit freaked out by it all, a bit claustrophobic with so many people.
We kept walking to the Shafston st exit, (about 3km i think), we would have walked all the way to the end at Wooloongabba but I had blisters and bigJ was really tired.
I thought it would be "prettier", but maybe they plan artwork or something for the white panels you can see in the photo.
It was very loud in there with the huge fans in the ceiling.
It is the longest tunnel in Australia- for now anyway, as they are building a longer one here out to the Airport.
You can see more about the tunnel at www.clem7.com.au including photos of the huge tunnel boring machines.
Afterwards we walked over the new pedestrian bridge "The Kurilpa Bridge" to the museum. If you click this photo you can see some photos of the bridge and the river as well as more of the Clem7 tunnel.
