The A34 Road bridge spans the River Thames flood plain the Railway and the Oxford Canal. It is currently being replaced, I made a trip down the canal to Dukes Cut last night because there was going to be an incredible engineering feat take place. Many hundreds of tons of concrete and steel road deck were going to be slid sideways to mate up with another road deck.
Travelling along the canal this is the first indication you get that something is about to happen. You can see it from some considerable distance. this is not a small crane though I have seen bigger in Dubai.
This was the gap to be traversed, from left to right. There are steps in the scaffold tower to give some scale. The pipes you can see on the decks just under the railings will be side by side in the morning.
Here the civil engineers are jacking up the deck on one of the supports to a height of 12mm. There are 6 or 7 supports so this is not just a bit of road but some distance.
This shows a closer view of one of the vertical jacks and the horizontal jack.
The crane is at one end of the deck to be moved and from where I am standing there is a greater distance to the other end behind me.
At this point in the proceedings my batteries went flat and I popped off to get more and a cuppa . . . . . well I woke up at gone 3 in the morning. Ho hum!
