London Bridge is falling down

You'll recall that Thameslink 2000 is the £6bn scheme to upgrade the main north-south cross-London railway, and much of the cash is being spent here:


London Bridge station is in the foreground, Cannon Street above it (over the river), and snaking around the back is the connection to Blackfriars, Charing Cross and Waterloo East.


One of the biggest bottlenecks was over Borough Market, and Thameslink 2000 involves the demolition of a corner of it and the insertion of a huge new bridge.


With the railway closures over the Easter weekend, the bridge was slowly eased into place. It's a really interesting structure, a sort of double-bowstring (I've no idea if that is the correct technical term for it):


I rather like that shape. More importantly, it will allow around 24 trains an hour to squirt each way through central London.


While Thameslink 2000 may, so far, be more than 11 years behind schedule (and it will be closer to 18 years behind schedule when it finally, fully opens), it's a vitally important piece of upgrading and it's nice to see the new bridge in place.

Interesting: must go and see ... The welds look neat but not over-substantial.

I hope welding technology is now up to the job, though. Remember the Freeman Fox designed box girder bridges that so spectacularly were not?
