On June 30, 1894, the Prince and Princess of Wales officially inaugurated the bridge. The bridge linked Horselydown Lane, which is now Tower Bridge Road, to Iron Gate, which is now Tower Bridge Approach. It was a three-lane structure with a center lane for vehicles. The approach lanes were one way northbound and southbound. The main span was a single tower with an octagonal pavilion on top. The bridge was made of iron with wood framing and was 100 feet wide and 300 feet long. The prince used a small cannon from the royal navy to fire a 21-gun salute when the bridge first opened in 1894. This ceremony was repeated the following year when the bridge was reopened after being repaired following its original construction in 1883. The prince also fired a 21-gun salute when the bridge was opened to traffic on New Year's Eve 1897 and again on May 11, 1911, the day before Queen Victoria died. The last time he fired a gun was on January 9, 1913, the day before his father King George V came to the throne. Tower Bridge has had many names over the years but it always has been known as the Prince of Wales' Bridge until it was renamed in memory of Edward, Prince of Wales, in 1956.
