  Details regarding the 1904 reinforcement project: "...It was therefore decided to renew all the suspension rods, and pins, and to fix steel cables above the suspension links, to supplement them so that the maximum stress in the links due to any possible travelling load should not exceed 5 tons per square inch. It was also decided to build a stiffening girder coupled to the suspension rod on each side of the bridge, and at the same time to widen the bridge by building a footway 6ft. wide outside the suspenders on the north side of the bridge."

Notes:

• 1839 (or 1840): Restored. Deck strengthened.
• 1893: Original wood deck replaced with a steel deck.
• 1938-1940: Original wrought-iron chains replaced with steel eyebars, deck strengthened.
• 1999: Deck resurfaced and other improvements to strengthen bridge.
• 2020: Major maintenance project planned to start January, 2021.
• 2022, October: Closed due to serious structural concerns. Expected to reopen January 2023 with a weight restriction.
• Became longest suspension bridge by eclipsing 1820 Union - Horncliffe, Berwick-upon-Tweed vicinity, England and Fishwick, Scotland, United Kingdom.
• Eclipsed by new longest suspension bridge 1834 Zaehringen (Grand Pont Suspendu) - Fribourg, Switzerland.

Notes:

• Provided access to the lighthouse at South Stack. Iron chain suspension system replaced in 1964, surviving until until 1983, but unclear if it was still functioning as a suspension bridge. Towers are now used as abutments for a pedestrian truss bridge.

Notes:

• 1906: Replaced by a non-suspension bridge still referred to as "Chainbridge".

Notes:

• Replaced by a stayed footbridge, opened 1984.
• See 1922 Llanstephan - Llanstephan, Wales, United Kingdom. This small vehicular bridge in nearby Llanstephan is sometimes misattributed as being located at Builth Wells. It is not.

Notes:

• Based on Dredge's patent.

Notes:

• Dredge patent bridge, possibly completed by his son William Dredge.

Notes:

• This entry refers to the steel suspension footbridge nestled between Telford's suspension bridge and Stephenson's rail bridge. Click the photo to get a better view of this bridge. According to Susan Ellis, Senior Archivist of the Conwy County Borough Council, the bridge was built on the recommendation of John J. Webster who was hired to inspect Telford's suspension bridge in 1902 "following fears about the safety of its condition. He reported back making various recommendation for strengthening the bridge, including that a separate footbridge be constructed."
• This footbridge was in existence until at least 1957.
• Next to 1826 Conwy (Conway) - Conwy, Wales, United Kingdom.

  This detailed account of the 1904 reinforcement of Telford's adjacent bridge does not mention the existence of, or building of, an additional footbridge. It does describe adding a cantilevered walkway to one side of Telford's bridge. This walkway was, indeed, built, and can be seen in the linked image on the left side of the older bridge. Thus, it is not entirely clear whether this bridge was actually constructed in 1904 and the work of Alfred Thorne (who was very much associated with the Telford bridge reinforcement project)

Notes:

• Rebuilt twice.

• A thorough report on these bridges was published in 2010 by the Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW), Chain Bridge, Llantysilio, Denbighshire. The Pickering bridge (built 1817, according to the report) was contructed with the deck laid on the chains. This bridge was removed in 1870 but appears not to have been replaced until at least 1876. The new bridge, not simply refurbished, was constructed with the deck supported by the chains underneath, but in an "underspanned" fashion with small pillars resting on the chains, supporting a level deck. This bridge was destroyed by flood on Feb. 16, 1928. The report also investigates whether the chains of the current (1929) bridge are the original chains from the 1817 Pickering bridge and concludes there is evidence "supporting the hypothesis that the chains we see on the bridge today are same as those put on the bridge in 1817" and adds "If the present chains are the originals, there is little reason to doubt that they are the oldest suspension bridge chains in the western world."
• 2015: Underwent major restoration and reopened.

  "The suspension bridge used to be renowned for its wobbly midpoint and was a key shortcut across the River Conwy for locals and tourists. However, structural reviews conducted last year found that virtually the entire bridge would need to be refurbished, with the entire timber deck as well as other parts replaced completely."

Notes:

• Allan Agate writes: "I was the Project Engineer for this footbridge and can therefore confirm it was designed and built by David Rowell Ltd and almost certainly the last suspension bridge they built. It was a hybrid of earlier bridges making use of new bolted hot rolled sections instead of riveted composite tower construction. The date was about 1962/3." I am not sure of the provenance of the 1958 date associated with this bridge and I don't have reason to question Mr. Agate's recollection of the bridge completed a few years later.
