The Çatalan Bridge (Turkish: "Çatalan Köprüsü" ), also known as the West Bridge (Turkish: "Batı Köprüsü" ), is a 1575 m long bridge crossing the Seyhan Dam Lake in Adana, Turkey.  The bridge connects the city of Adana to the villages and vacation homes north of the lake.  Despite crossing the Seyhan Dam Lake, the bridge is named after the Çatalan Dam, which is 14 km north and the next dam upstream on the Seyhan River.  The Çatalan bridge was the longest bridge in Turkey from its construction in 1998 to 2007, when it was surpassed by Viaduct No. 1 near Bolu and the longest bridge crossing a body of water until 2016, when it was surpassed by the Osman Gazi Bridge near Gebze. Waterloo Bridge ( ) is a road and foot traffic bridge crossing the River Thames in London, between Blackfriars Bridge and Hungerford Bridge.  Its name commemorates the victory of the British, the Dutch and the Prussians at the Battle of Waterloo in 1815.

The Garden Bridge project was a private proposal for a pedestrian bridge over the River Thames in London, England.  Consequent on an idea of Joanna Lumley, Thomas Heatherwick worked with Arup on a proposal by Transport for London (TfL) for a new bridge across the Thames between Waterloo and Blackfriars bridges.  The proposed concrete, steel, cupronickel clad structure was intended to carry pedestrians, with no cycles or other vehicles.  It was to have been located some 200 m from Waterloo Bridge and 300 m from Blackfriars Bridge, and have included some areas of planting.  The project included a commercial building, built on former green space at the southern end of the bridge.  The bridge could only be funded by raising over £140 million of private money (including charitable gift aid) and £60 million of promised public money, of which £30m was from Transport for London (£20m of this to be repaid over 55 years) and £30m from the Department for Transport, adding up to projected funding of over £200m in total, In January 2017 the trustees of the prospective owner of the bridge stated that costs would "substantially exceed" an earlier revised total of £185m and in April 2017 the report by Margaret Hodge (below) concluded, on the basis of the Garden Bridge Trust's own evidence to her, that the cost would be over £200m.
