Chain tramroad tunnel

George Hargreaves & Co sank the shaft of Grimebridge Colliery in 1851 and soon after a 'ginny road' was built across the moors to transport the coal tubs to the road up the valley from Waterfoot. The line operated for at least 90 years before the coal was routed through the hill to a wharf near Old Meadows on the Bacup to Burnley road.

There were three tunnels on the line and this is the interior of one of these. It is about four feet high and would have held a double track plateway for the tubs.
