Imagine my delight to find the UK’s Sp!ked covering my hometown’s ‘Big Dig’, the largest public works project in history.
“The construction of tunnels under the old highway, while the traffic flows unimpeded, has required some innovative technology. Sub-zero temperature brine is pumped through pipes to freeze the ground solid. Tunnelling can then take place without disturbing roads, trains, or building foundations, and when this is complete the ground thaws out.”
And here’s The Big Dig’s website.
