In addition to the 1902 addition of cables, the bridge has been strengthened and refurbishment on many occasions. The bridge deck was substantially renewed in 1871, and again in 1974, with the chains reinforced at intervals throughout its life.
The bridge was closed to motor vehicles for several months during 2007. A newspaper report available online indicates that the closure happened shortly before 12th April 2007 and was due to one of the bridge hangers breaking. The affected hanger has temporarily been replaced with threaded bar to allow the bridge to reopen to motor vehicles. This losure led to the formation of the Project 2020 group.
In December 2008 the bridge was closed to traffic as a result of a landslide.
