Nice pics Graham, was it of the back of a lorry or of the back of a crane they fell from?



Yes it is, its the N25 Suir River Bridge crossing in Co Waterford, recently completed by Ascon in joint venture with Dragados just upstream of the city. i think there was an article in the Engineers Ireland Journal a few months back on it but I havnt found a digital version yet, have it in hard copy at home somewhere. In the mean time heres the link to its website: http://www.waterfordcity.ie/n25bypass/bridge.htm

•Overall width: 30.60m
•Over length: 465m

Pity they couldnt have made it 5m longer
•Side span lengths: 40, 70, 90, (230), 35m
•Clearance over MHWS: 14m above MHWS

Why is "phonetically" spelt with a "ph"?

... It's better to be silent and thought a fool, then to speak up and remove all doubt

The complex of Newgrange was originally built between c. 3100 and 2900 BC,[2] meaning that it's aproximately 5,000 years old. According to Carbon-14 dates,[3] it is more than 500 years older than the Great Pyramid of Giza in Egypt, and predates Stonehenge by about 1,000 years.
