A floating tractor has been helping to reopen Standedge Tunnel, blocked by a build up of silt during the recent heavy rains.<\/p>\n

The specialist \u2018amphibious tractor\u2019 was used to clear a blockage that built up during the recent heavy downpours that caused widespread flooding across the North of England and blocked Britain\u2019s longest and deepest canal tunnel. It is thought that during the unprecedented wet weather, approximately 8-9 cubic metres of sand, gravel and other debris were swept into the tunnel by a stream that flows into the tunnel about 250 metres from its entrance at Diggle.<\/p>\n

\"amphibious<\/p>\n

The unusual work required the help of a specialist mining consultant.\u00a0 A hydraulic bucket on the front of the amphibious dredger, known as a Truxor, was used to clear the blockage so that boats can once again navigate the 3\u00bc miles through the tunnel.<\/p>\n

Mark Weatherall, senior project manager at the Canal & River Trust, comments: \u201cStandedge Tunnel is such an amazing engineering achievement.\u00a0 200 years ago, navies used picks shovels and dynamite to carve their way 3 \u00bc miles from one of the tunnel to the other.\u00a0 Today, it\u2019s popular with boaters and tourists and it\u2019s important that we carry out this specialist work to get the tunnel and navigation open to the public.<\/p>\n

\u201cWorking deep underground in a tunnel on a floating dredger is quite unusual and poses many new problems which, I am proud to say, the team have successfully overcome in a short period of time.\u00a0 Not only have we had to bring in specialist equipment, we\u2019ve had to take specialist advice from a mining consultant who is experienced in confined spaces to make sure that the work is undertaken in a safe and efficient way.\u201d<\/p><\/blockquote>\n

Standedge Tunnel is over 200 years old and known as one of the Seven Wonders of the Waterways.\u00a0 The works to clear the blockage will ensure that the popular visitor attraction, which includes passenger trips into the tunnel, will reopen for the summer season as planned on 19th March.<\/p>\n
