    A public consultation has opened for a new road crossing of London's River Thames. The idea is for a new tunnel to the east of the city to relieve the enormous traffic strain on the existing Dartford Crossing. For over 50 years, the Dartford Crossing has provided the only road crossing of the Thames east of London. This spectacular choke point, partly caused by tollbooths, consists of two bored tunnels and a bridge.

  • Think global act local
    As the magazine went to press the International Tunnelling and Underground Space Association (ITA) released statistics about emerging demand for tunnelling as well as the need to bring young engineers into the industry. The report says between 2009 and 2013 the global tunnelling and drilling equipment industry reached a 4.9 per cent annual growth rate, which will likely be sustained through to 2018. Much of this is due to demand in Asia, which had nearly half the market share in 2014.
