A vertical-lift bridge or lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck.
The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridge. Generally speaking they cost less to build for longer moveable spans.[1] The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use.
Although most vertical-lift bridges use towers, each equipped with counterweights, some use hydraulic jacks located below the deck. An example is the 52-foot (16 m) span bridge at St Paul Avenue in Milwaukee[2] (see also table bridges). Another design used balance beams to lift the deck, with pivoting bascules located on the top of the lift towers.[3] An example of this kind was built at La Salle in Illinois, USA.
The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it. This is a result of the deck remaining suspended above the passageway.

- Bridges 5 (Glendale Avenue Bridge), 11 (Allanburg Bridge) and 21 (Clarence Street Bridge) on the Welland Canal, all built during the late 1920s as part of the Fourth Canal expansion project (1913–1932). In addition, there are also Bridges 13 (Main Street Bridge), 17 (Dain City Railway Bridge) and 18 (Forks Road Bridge) on the Welland Recreational Waterway (a former channel of the Welland Canal). However, these bridges have not been operational since 1973. Bridges 13 and 18 have had their counterweights removed while the machinery for Bridge 17 has been dismantled. In addition, Bridge 18 no longer possesses its towers; they were removed for ease of maintenance.

France
The Pont Jacques Chaban-Delmas's approx. 110-metre (360 ft) lift span is likely the longest in Europe,[4] but that of the Pont Gustave-Flaubert is very nearly as long.
- Pont Gustave-Flaubert – crossing the Seine at Rouen, this lift bridge is the highest vertical-lift bridge in Europe,[citation needed] allowing ships up to 55 m tall to pass under it. It is 670 m long, with a span of 116 metres[6]. A striking design feature, the two road sections are mounted outside the central towers. The bridge was designed by François Gillard and Aymeric Zublena and opened to road traffic on 25 September 2008. It is named after the author Gustave Flaubert who was born in Rouen.[7]

- The Pont Jacques Chaban-Delmas, spanning the River Garonne in Bordeaux, was opened in March 2013. The central lift span is 117m long and can be lifted vertically up to 53m to let tall ships pass underneath. The bridge is 575m long with the central lift span weighing around 2,600 tonnes. Its width varies from 32 to 45m and it will be used by cars, trams, cyclists and pedestrians. It can handle 43,000 vehicles a day and will reduce traffic congestion in Bordeaux.[9] Structurae gives a length of 110 m for the lift span,[10] making it probably the longest vertical-lift span in Europe.[4]
