On July 26th 1820 the Union Chain Bridge, across the River Tweed was opened.
The Union Chain Bridge spans the River Tweed between Horncliffe, Northumberland, England and Fishwick, Borders, Scotland. It was designed by Captain (later Sir) Samuel Brown RN, who held patents for the design of the chains, although Brown altered the tower and abutments on the suggestion of John Rennie. When it opened in 1820 it was the longest wrought iron suspension bridge in the world with a span of 137 metres (449 ft), and the first vehicular bridge of its type in the country.
It cost £7,700 to construct and pre-dates the Clifton Suspension Bridge and the Menai Bridge, which are of similar design . Today it continues to carry traffic, and visitors can enjoy pleasant walks along the river bank. Just up the hill from the Union Chain Bridge on the English side is the Chain Bridge Honey Farm, where there is situated a permanent exhibition on chain suspension bridges.
Downstream on the Scottish side is Paxton House, where visitors can see Alexander Naismith's depiction of Union Chain Bridge, painted before its actual completion, as seen in the second picture.
Before the opening of the Union Bridge, crossing the river at this point involved an 11-mile via Berwick upon Tweed. Until 1885, tolls were charged for crossing the bridge; the toll cottage, being at the English end, was demolished in 1955.
The bridge reopened in 2023 after a major £10.5 million restoration. it has been recognised as an International Historic Civil Engineering Landmark, joining the likes of Sydney Harbour Bridge and The Eiffel Tower.
