Latest update 29th April

The weather finally improved enough for me to pay a visit to the work sites.  I don't think I can remember so much rain falling for such a long period, certainly the wettest period of official drought!  First surprise was the normal access to the west side of the main line by the scrapyard was impassable .  The river Hiz was in spate and the footpath was completely under water as my first photo shows. Actually this shouldn't have been a surprise considering the amount of rain that had fallen!

The footpath is normally to the right hand side of the bridge

I was forced to take a two mile detour by car and access via the Icknield Way in Ickleford.  Bury Mead Springs conservation area was very waterlogged but I was able to make my way up on to the former Bedford line embankment. 

 This is the remaining abutment of the bridge that crossed the Icknield Way.  Unsightly graffiti has been painted over.  Gerry's Hole is now full to overflowing.

Speaking of graffiti, the protective hoarding on the far side of the line has been the object of some local "artists" since my last visit.  This is right beside one of the fastest sections of the line and is certainly a stupid and dangerous place to do this.
Here you can see the tops of the recently poured piles.  The reinforcing steelwork is protruding from top.
I am pretty sure the two sets of blue hoardings mark the points where the new viaduct will cross the main line.  The graffitied one is behind the excavator on the left.
This is a group of steel reinforcing waiting to be poured with concrete
The piling machine is working right on the edge of the raised section which was the formerly the landfilled triangle between the two lines.
A shot looking south towards the scrapyard where not a lot appears to have changed.  There is however another piledriver which can be seen far centre.  I will take a look on the way back.
Finally a shot looking back on to the triangle. The edge seen here has been landscaped with top soil which suggest this is how it will end up.  However the fenced off section in the foreground still baffles me. It remains virtually untouched.n  I will check earlier photos because I have a feeling a gas main might have run through here.  Probably not a good idea to pile drive through that!!

Picture of the other pile driver between the two Cadwell Lane bridges.  Also some shuttering work to the right next to the gas main which you can just make out.
Turning round you can see a static cement mixer which is supplying the pile driver through a pipe buried under the road.  Quite a lot of surface water here.
Next to the mixer a semi-circle has been cut into the Bedford line embankment virtually right up to the main line embankment since my last visit.  This is for the second viaduct support pier.
Also the embankment between the two bridges has been stripped back

Finally work has commenced on the east side of the main line.  Top soil has been removed along the line of the new embankment and piled up at the side presumably for later landscaping.  This looks towards the Cambridge branch from the very end of Wilbury Way.  The former sewage treatment works is immediately behind.
Turning round, this is a shot through the treatment works towards the main line. This hasn't been cleared yet although you can see the pile driver behind.  Also you can just make out an East Coast express passing which marks the main line.
The main work site and offices.  More activity here now as well. Haul road in the foreground.
Final shot of the stripped area of the embankment just before it swings left to join the Cambridge branch.
This was taken from Hillgate on the east side of Wilbury Way.  There is a marked difference in the landscapes either side of the main line.  To the west it is mainly heavy clay as can be seen from the spoil from the pile driving.  This side it is chalk.

Piling work continues

Sorry for lack of updates.  Other commitments have prevented me from visiting the site.  However I did have a quick look last weekend and the piling work is continuing.  The machines have moved northwards and are obviously working along the line of the new viaduct.

It appears a lot of water is required during the piling operation, hence the large pipes.  The large square hole I had thought might have been one of the foundations of the viaduct is actually being used to take the wet spoil that is being removed.  I guess this dried out and moved onto the spoil heaps.































I moved further north into the field immediately adjacent to the work site.  This shot looks back at the growing spoil heaps.  To the left you can see the piling equipment in use on the other side of the main line.
A better shot of the same equipment.  This has also moved further north.
Finally a longer shot showing both sets of piling equipment.  In earlier pictures the equipment this side is much nearer the sphere seen on the far right.  I did take a look over near the main site compound and there is very little obvious change there.  I will visit again at the weekend all being well.

Construction work finally commences

 After some months of preparatory work, it appears that the actual construction of the new line has commenced.   Two sets of pile driving equipment have appeared on site, one each side of the main line.  Piles to support the piers of the new viaduct are now being constructed. 
Pile driver inserting the steel tubes.
Similar machine can be seen on the other side of the main line marked by an approaching East Coast express.
Stack of steel pile liners which are presumably poured with concrete. 
 A new row of site buildings has appeared during the past week, as a result of work scaling up I guess.
A pile of fencing and some gates waiting to be erected somewhere.  I can't upload any more photos this week as Google informs me I have reached the limit.  I will have to purchase some more storage space apparently, which will take up to 24 hours to become available.
Moving down to the river Hiz underbridge, the level has been raised again by quite a significant amount.  You can't see down to the other bridge now.  As I left I moved round to the other end and took the following picture by the scrapyard gates.
According to the Network Rail plans, the viaduct will start just the other side of the security fencing.
