Page "Bridge" Paragraph 46

Robert Stephenson's High Level Bridge across the River Tyne in Newcastle upon Tyne, completed in 1849, is an early example of a double-deck bridge.

The upper level carries a railway, and the lower level is used for road traffic.

Other examples include Britannia Bridge over the Menai Strait and Craigavon Bridge in Derry, Northern Ireland.

The Oresund Bridge between Copenhagen and Malmö consists of a four-lane highway on the upper level and a pair of railway tracks at the lower level.
