Newburn Bridge (Toll). This was a simple girder bridge, with rivetted trusses supported on pairs of cylindrical wrought iron piers filled with concrete. There were four spans, the piers at 103ft (31.5m) entres, and the road deck stood 21ft (6.4m) above high water. The bridge was designed by Messrs J W Sandeman and J M Moncrieff of Newcastle for the Newburn Bridge Company, and built in 1893 by Head Wrightson of Thornaby on Tees. It incorporated a 22in(0.56m) water main on either side and was originally a toll bridge {2}. Newburn Bridge consists of four 100ft spans in lattice steel. Noteworthy for the depth of the foundations. Each pier consists of a pair of 5ft diameter cylinders of wrought iron plating filled with concrete. The maximum depth to which they are sunk is 71ft below high water or 97ft below roadway level where rock was reached. The bridge was completed in 1893.

Some of the Throckley pits which had been worked over the 18th century were re-opened in the mid 19th century. Old routes may have been retained within the area of the colliery but a new line was established down to the River Tyne some way to the west of Lemington. This waggonway ran due south from the line of Hadrian’s Wall, and then circuitously through a narrow valley between Hallow Hill and Rye Hill taking it close to Newburn Grange, to the south of which it joined Wylam Waggonway (HER 1032). The route is shown on the first edition Ordnance Survey and is named Throckley Waggonway.

A Quarry. This is not shown on the 1st edition OS mapping, so dates from after 1858.

A Rifle Range, up to 600yds. This is not shown on the 1st edition OS mapping, so dates from after 1858.

Throckley Colliery. The Throckley Coal Company was formed in 1862 and included Major Stephenson, John Spencer (of Newburn Steelworks), Mr. Simpson and Mr. Boyd. The main drawing shaft - the Isabella shaft - was named after the wife of the company director. This was not the only shaft - the Derwentwater was the third shaft on the site. The coal seam exploited was the Brockwell seam. Opened in 1867. At its heyday it produced 120,000 tons of coal per year. At the turn of the twentieth century it employed 944 men. The colliery was not noted for any mechanisation by 1945. Coal production ceased in January 1954. Selected demolition/salvage had taken place of the Derwentwater winding machinery from 1938 to 1940.

A Reservoir. This is not shown on the 1st edition OS mapping, so dates from after 1858.

Raft Yard. It is not possible to tell from the 1st edition OS mapping, whether this was the name of the yard or its function. It is not shown on the 2nd edition OS mapping, so was possibly out of use by 1895.

Walker Copperas Works. This is possibly out of use by 1895, as it is not marked on the 2nd edition OS mapping.

A Brick and Tile Works. This is probably the site of Hunter's Brick and Tile Works, which worked from 1832 to 1921. Also known as French and Hunter's.

Southfield Copperas Works. This is possibly out of use by 1895, as it is not shown on the 2nd edition OS mapping.
