This was the site of Willow Bridge Colliery, a coal working which sprang up in the 1810s for at least a decade. It was sunk by 1819 as noted in the local newspapers which states it was "a new winning [with] two shafts sunk to the first seam at a depth of seventeen fathoms. There are two other seams both within twenty-five fathoms of the one that is recently sunk. The above colliery is in a most favourable situation being within one and a half miles of the river Blyth to which leave is granted for a railway and a quay which is already built for the shipment of coal.

It is worthy of note that this working was partly owned by George Stephenson. He invested £700 in the colliery, and used it for leverage in dealing with the Bedlington Iron Works. This pit provided them coal, and the favourable relationship led to contracts for locomotive parts and rails for the Stockton & Darlington. It was partly owned by another fellow named Mason, and it was later owned by the Barrington Coal Co. The Longridge's at the Bedlington Iron Works went on to own Barrington Colliery.

There is no visible evidence today, but the LiDAR readings do show evidence of earthworks and a small heap. It totally vanishes by the mid 19th century, and not even a label is apparent on the Ordnance Survey maps.
