Brockdale Bridge

The Brockdale Bridge was a bridge spanning an unknown river. It was built around 1985 and destroyed by Death Eaters in the Summer of 1996.

History
About ten years old in 1996 at the time of its destruction, the bridge collapsed and killed a large number of Muggles who were driving on the bridge at the time. In the summer of 1996, Lord Voldemort ordered Cornelius Fudge to step down from his position as Minister for Magic, with the threat of a mass Muggle killing if he did not do so; Fudge refused to step down, and thus Voldemort ordered Death Eaters to cause the Brockdale Bridge to collapse. Fudge was replaced by Rufus Scrimgeour soon after.

Behind the Scenes
The Millennium Bridge was used in the film to represent the Brockdale Bridge from the book, but is never actually mentioned as being the Brockdale Bridge. It was used for Dramatic Effect only (directors license to change what he wishes to sell more tickets), since it is a bridge known throughout the world, and since it too is about 10 years old, but here is where the similarities end. The Millennium Bridge is in fact a pedestrian bridge, yet in the book the Half-Blood Prince (on page 2, line 5), it is mentioned that upon the Brockdale Bridge's destruction, "a dozen cars" fell into the river.

Using the above picture of the destruction of the Millennium bridge from the movie, you can conclude using simple trigonometry comparing measurements of the bridge to those of the width of the river, or the height of St. Pauls' or any other known measurements of the surrounding buildings, that the width of the bridge is 13 ft. at its widest, and is thus NOT a road bridge, and can only be a footbridge, thus that the movie contradicts the high canon of the Book, and thus the movie DOES NOT depict the Brockdale Bridge, David Yates thus changed the story (he chose which bridge to destroy, and where) and the timeline (since the Millennium bridge was started in 1998 and completed in 2000, yet the Brockdale bridge was destroyed in the summer of 1996) to destroy the Millennium Bridge. Thus, even after the film, we currently do not possess the actual name of the river or even the actual city of which the Brockdale Bridge is said to have resided. All we know is that the Brockdale Bridge MUST be in the United Kingdom (not necessarily only England), that it spans a river but we don't know which, and that it is probably a road bridge, but possibly could be a rail bridge as it may be referring to train cars, however, that it definitely is not a pedestrian bridge.
