The Pearl Harbor Memorial Bridge, informally the Q Bridge, carries Interstate 95 over New Haven Harbor in Connecticut and is the first extradosed bridge in the United States.
Pedestrian bridges in the United States by state
Pedestrian bridges in the United States by state surveys how footbridges are defined, registered, counted, and funded across the states, drawing on the National Bridge Inventory, the National Register of Historic Places, and state inventories.
Plate girder bridge
A plate girder bridge is a steel bridge supported by built-up I-shaped girders made from welded or riveted plates, widely used for spans of roughly 30 to 100 m.
Pont des Arts
Pont des Arts, also called Passerelle des Arts, is a pedestrian footbridge over the Seine in Paris linking the Louvre with the Institut de France.
Pontoon bridge
A pontoon bridge is a bridge carried on floating vessels or pontoons rather than piers, used since antiquity and still standard for military wet-gap crossings.
Post-tensioned concrete bridge
A post-tensioned concrete bridge is a concrete bridge whose superstructure is prestressed by steel tendons stressed with jacks after the concrete hardens, widely used in United States bridge building.
Pratt truss
The Pratt truss is a bridge truss with diagonals in tension and verticals in compression, patented by Thomas and Caleb Pratt in 1844 and once the most common US bridge form.
Precast segmental construction
Precast segmental construction is a bridge-building method in which concrete segments cast in a plant are joined into a continuous span by post-tensioning, first used in Europe in the 1950s.
Puente de la Mujer
Puente de la Mujer (Spanish for "Woman's Bridge") is a cable-stayed swing footbridge over Dock 3 of Puerto Madero, Buenos Aires, designed by Santiago Calatrava and inaugurated in 2001.
Pyrmont Bridge
Pyrmont Bridge is an electric swing bridge of 1902 crossing Darling Harbour in Sydney, designed by Percy Allan and one of the world's oldest surviving electrically operated swing bridges.
Retractable bridge
A retractable bridge, also called a thrust or traversing bridge, is a movable bridge whose deck rolls back from the navigation gap rather than lifting, swinging, or curling aside.
Rio–Antirrio Bridge
The Rio–Antirrio Bridge (Γέφυρα Ρίου-Αντιρρίου), officially the Charilaos Trikoupis Bridge, is a cable-stayed road bridge in Greece linking Rio on the Peloponnese with Antirrio, inaugurated in 2004.
Rolling lift
Rolling lift is a bascule bridge where the span rolls along a curved track rather than pivoting, as in the design patented by William Scherzer in 1893.
Saint-Thibéry Roman Bridge
Saint-Thibéry Roman Bridge (pont dit romain de Saint-Thibéry): ruined stone arch bridge over the Hérault at Saint-Thibéry, France. Long called Roman and tied to the Via Domitia at Cessero, its surviving masonry is medieval (c. 1150–1250), nine arches, four remain, classified 1862.
Scherzer rolling lift
A Scherzer rolling lift is a movable bascule bridge whose span rolls backward on curved segmental girders as it opens, patented by William Donald Scherzer in 1893.
Segmental bridge
A segmental bridge, also called a segmental concrete bridge, is a concrete bridge whose deck is built from short segments joined by post-tensioning, first used in Europe in the 1950s.
Self-anchored suspension bridge
A self-anchored suspension bridge is a suspension bridge whose main cables anchor to the stiffening girder itself, eliminating massive ground anchorages and suiting spans of roughly 100–400 m.
Simple suspension bridge
A simple suspension bridge is a bridge whose walkway lies on or between two sagging cables anchored at each end, without vertical suspenders, so it is restricted to pedestrians and suits difficult terrain.
Skyway
A skyway is an enclosed, elevated pedestrian walkway that connects buildings above street level, protecting walkers from weather; the first modern system opened in Minneapolis in 1962.
Smithfield Street Bridge
The Smithfield Street Bridge is a steel lenticular through-truss highway bridge over the Monongahela River in Pittsburgh, designed by Gustav Lindenthal and opened in 1883, the oldest river bridge still standing in Allegheny County.
Stay cable
A stay cable is a tensioned steel member running directly from a bridge tower to the deck, the defining element of cable-stayed bridges since Sweden's Strömsund Bridge of 1955.
Stay cable systems
A stay cable system is the complete engineered product that carries a cable-stayed or extradosed bridge deck in tension from deck to pylon, including strands, anchorages, and dampers.
Stay-cable maintenance and monitoring
Stay-cable maintenance and monitoring is the inspection, condition assessment, and replacement of stay cables on cable-stayed bridges, where corrosion hidden inside anchorages threatens service life.
Stressed ribbon bridge
The stressed ribbon bridge, or catenary bridge, is a tension structure like a suspension bridge with the cables embedded in a thin deck following a catenary arc.
Suspension bridge
A suspension bridge is a bridge whose deck hangs from main cables draped over towers and anchored at each end, allowing the longest spans of any bridge type.
Swing bridge
A swing bridge, also called a turntable bridge, is a movable bridge whose span rotates horizontally about a central pivot pier, clearing the waterway for passing vessels.
Swing footbridge
A swing footbridge is a pedestrian or cycle bridge whose deck rotates horizontally about a vertical axis on a pivot pier, letting boats pass through the gap.
Tees Transporter Bridge
The Tees Transporter Bridge, also known as the Middlesbrough Transporter Bridge, crosses the River Tees between Middlesbrough and Port Clarence on a suspended gondola. Opened in 1911, it closed in 2019.
The Rolling Bridge
The Rolling Bridge is a movable footbridge at Paddington Basin in London that opens by curling into a circle. Designed by Heatherwick Studio, it was completed in 2004.
Through arch bridge
A through arch bridge is an arch bridge in which the arches rise above the deck and the roadway passes between them, usually suspended from the arch ribs by hangers.
