All this talk of Blyth pier has got me interested in it's history. I have spent most of today trawling the internet searching for anything I could find about it's history. There is surprisingly little to be found. I did find a site which listed chronologically the history and development of Blyth Harbour and Blyth Harbour Commission.
Chronology:
* 1689 Quay established on the north side of the River Blyth, c.1689.
* 1723 First facility appears on the south side of the River Blyth with the construction of a coaling quay.
* 1727 Ballast quay built.
* 1728 800 yards (c.730 metres) of quay built.
* 1729 Pilot's Watch house built.
* 1730 Lighthouse and quay extension built.
* 1882 Blyth Harbour Commission established by Act of Parliament.
Entities Involved:
Blyth Harbour Commission: Established.
* 1884 By 1884 the NER had constructed 1,100 feet (c.335 metres) of staiths at Low Quay, a new dredger had been bought, the entrance channel was improved and a ridge of rock in mid harbour was removed.
Entities Involved:
North Eastern Railway (NER): Commissioned work.
* 1885 New west breakwater completed, 2470 feet (c.753 metres) in length.
* 1886 East breakwater extended by 1000 feet (c.305 metres) using mass concrete.
* 1887 A new channel with a depth of 3 metres at low water, was dredged about 65 metres to the west of the old channel, thus clearing a reef of rocks on the line of the old channel which extended for 1,500 feet (c.457 metres) outside the pier head.
* 1888 Two additional coal staiths constructed by the NER on the south side of the harbour.
Entities Involved:
North Eastern Railway (NER): Commissioned work.
* 1896 With new collieries being sunk to the north of the river, four additional coal staiths were erected by the NER on the north side.
Entities Involved:
North Eastern Railway (NER): Commissioned work.
* 1898 Entrance channel widened and deepened.
* 1899 New South Harbour with some 23 acres of deep water opened.
* 1913 New harbour offices opened.
Entities Involved:
River Wear Commission:
* 1928 New West Staiths opened.
Entities Involved:
Blyth Harbour Commission: Commissioned work.
North Eastern Railway (NER): Commissioned work.
* 1934 Two more south-side staiths opened.
* 1964 South Staiths closed and replaced by a general cargo quay.
* 1967 Cowpen North Staith closed.
* 1972 North Staith area developed as a bauxite handling facility with a deep water berth capable of accommodating 22,500 ton, 32 feet (c.10 metre) draft vessels.
In everything I read, I found no mention of a "Middle Pier".
I know that in the early 1700's a crude stone breakwater was errected on the East (Cambois) side of the river; this was when they were starting to develop the port.
In 1730 a lighthouse was built; this is the one behind Bath Terrace and was known as "The High Light"; it worked in conjunction with "The Low Light" which was a smaller and lower structure seen in one of Alan's attached photos. Ships would line themselves up while out at sea so that they could see one light directly above the other and this gave them a straight and safe run into the harbour.
In 1884, a large ridge of rock was removed from mid-harbour. It doesn't say how it was removed or where it was removed to. I wonder if this was broken up and now forms the Peeping Toms Rocks???
1885 the West Breakwater (Blyth Pier) was completed and in 1886 the East Breakwater (Cambois Pier) was extended using concrete and the lighthouse was errected on the end.
I can't find any mention of any other piers. So I enlarged the image in Alan's attachement up to 400%. It is quite blurred but the dark spot which appears to be at the end of a structure in the middle of the harbour is actually the very top of a pole in the foreground alongside the railway carts on the track, probably a light or something. The thing that seems to be a structure in the middle of the river in my opinion is probably the jib of the steam crane mentioned in the text below the photo.
If you look on Google Earth in close up you will see that the stone jetty runs almost exactly parallel to Cambois pier and in a direct line with the end of Blyth pier. The possible structure in Alan's photo seems to be running at about 45 degrees to the stone jetty and out towards the entrance to the harbour; I can't think of any reason for a pier to be there or for it to run in that direction. It's a strange one but I'm fairly certain that it's something other than another pier; and I don't suppose there is anyone left alive that could comment on it.
