The Wearmouth Bridge is a through arch bridge across the River Wear in Sunderland. It is the final bridge over the river before its mouth with the North Sea.

The current bridge is the third Wearmouth Bridge in its position. The first opened in 1796, and then was reconstructed in the 19th century.

History

The first bridge, 1796–1929

The cast-iron bridge of 1796

The first Wearmouth Bridge opened in 1796, with the foundation stone having been laid in September 1793. It was sponsored by Rowland Burdon, the MP, and designed by Thomas Wilson.^[1] According to the plaque on the current bridge, its construction "proved to be a catalyst for the growth of Sunderland," since access between Monkwearmouth and Bishopwearmouth had previously only been by ferry, with the nearest bridge at Chester-le-Street. There was originally a toll for traffic and pedestrians, although tolls for pedestrians were abolished in 1846.

It was the second iron bridge built after the famous span at Ironbridge, but was over twice as long with a nominal span of 240 feet, and only three-quarters the weight. Indeed, at the time of building, it was the biggest single-span bridge in the world (72 m), matching the collapsed Trezzo Bridge.^[2] It opened to traffic on 9 August 1796, having cost a total of about £28,000.^[3]

1805 repair and 1857 reconstruction

In 1805 the bridge had to be repaired after heat from the sun caused some of the cross tubes to fall out.^[4]

From 1857 to 1859 it was reconstructed by Robert Stephenson, who stripped the bridge back to its six iron ribs and levelled the hump in its middle by raising the abutments. The bridge was reopened in March 1859, with the toll completely abolished in 1885.^[3]

The current bridge, 1929–present

To accommodate the growing volume of traffic, construction began on the current bridge in 1927. It was designed by Mott, Hay and Anderson and fabricated by the famous bridge building firm of Sir William Arrol & Co. at their Dalmarnock Ironworks in Glasgow (they also built the famous Forth Rail Bridge and the steel structure of Tower Bridge in London).^[5] The new bridge was built around the old one to allow the road to remain open.^[4] It was opened on 31 October 1929 by the Duke of York (who would later become King George VI).^[6]

The cost of the bridge amounted to £231,943 of which £12,000 was spent on dismantling the old bridge.^[6]

It is described by Nikolaus Pevsner, the recognised authority, as being uninteresting, unlike the first, which he calls "a structure of superb elegance".

The adjoining railway bridge was built in 1879, and extended the railway south from Monkwearmouth to the centre of Sunderland.^[7]

Further up the river, another bridge, the Queen Alexandra Bridge, was completed in 1909, linking the areas of Pallion and Southwick.^[8]

The bridge carries the A183 road between Chester-le-Street and South Shields and the A1018 which was the old route of the A19 until the bypass was built leading to the Tyne Tunnel. It is a Grade II listed building. ^[9]
