A few photos from the community site visit on Saturday as provided by the Connexion Alliance (photos weren't allowed on the day):
The old Bowden station building. The platform is also heritage listed so will be retained. If you look closely you can see the black fence posts where it will be fenced off from the cutting.
The excavation for the new station. Drainage will be via a large sump that's been installed which will be pumped to the new stormwater drains. An old rubbish pit was found in this area which contained waste from the 1980s and before. The top of the pit contained an assortment of 80s memorabilia including a tie-die jumper, football boots etc. Further down was the shell of an old car and some other interesting stuff.
From memory the little structure you can see in the bottom right corner of the photo will be the control room for the new station. The floor level of this room will be approximately at platform level.
Interestingly, this gap in the bridge deck between the north and south carriageways of Park Terrace is there to reduce the overall length of the covered sections of track to ensure they are not classed as a tunnel, which would mean much more red tape etc would be required in terms of escape stairs, ventilation etc:
Here the cutting is at 8m depth - the finished depth being 11m. The cutting is being done in stages to prevent the need for the crews shotcreting the piles to work at height. The first stage of excavation is done, the piles are cleaned, then shotcreted, then the second stage is done etc. The shotcrete will be the final finish of the piles in this section in an effort to deter graffiti.
Further towards Adelaide - the southern cutting wall in this section will be an embankment, not piles.
Some more pile capping underway.
We also had a talk from the environment/heritage expert on site. Interestingly, in the last few days a tunnel has been uncovered which leads from the hanging room of the Adelaide Gaol underneath the railway tracks and towards the Torrens.
By all accounts there are a few people going - any other SA members invited?
