Pier
A raised structure providing access to offshore waters.
A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piles or pillars, providing above-water access to offshore areas. Piers have been built for several purposes, including fishing, boat docking, passenger and cargo access, and oceanside recreation, and their open structure allows tides and currents to flow relatively unhindered. The term pier has different nuances in different parts of the world: in North America and Australia it often implies a cargo-handling facility, while in Europe it is principally associated with Victorian cast iron pleasure piers that emerged in Great Britain during the early 19th century.

Lore & Background
Piers can be categorized into different groupings according to principal purpose, though there is considerable overlap. Working piers were built for handling passengers and cargo onto and off ships or canal boats, and fall into two groups: longer individual piers at ports with large tidal ranges, and shorter finger piers at ports with smaller tidal ranges. The advent of container shipping made working piers largely obsolete for general cargo, though some survive for passenger ships or bulk cargo, such as the Progreso Pier in Yucatán, which extends more than 4 miles into the Gulf of Mexico and is the longest pier in the world.
Reader's Guide
The introduction of steamships and railways permitted mass tourism to seaside resorts, and pleasure piers allowed holidaymakers to promenade over and alongside the sea. Many piers are floating piers to ensure they raise and lower with the tide, preventing damage to boats from overly taut or loose tie-lines. Piers have been built for several purposes, and their significance varies regionally: in Europe they are associated with Victorian pleasure piers, while in North America and Australia they often imply cargo-handling facilities. The National Piers Society gives a figure of 55 surviving seaside piers in England and Wales.

Frequently Asked Questions
What exactly is a pier in transportation terms?
A pier is an elevated structure that extends outward from a shoreline into a body of water, held up by piles or columns beneath it. Its core function is to give people and vehicles a stable, above-water pathway to areas that would otherwise be offshore.
What are the main purposes of building a pier?
Piers are constructed for a range of activities, including boat docking, loading cargo and passengers, supporting fishing operations, and providing recreational waterfront access. Their open framework is a deliberate design choice that lets tides and currents flow through with minimal resistance.
What is the longest pier in the world?
The Progreso Pier in Yucatán, Mexico, stretches over 4 miles (6.4 km) and holds the overall record for the longest pier. Among pleasure piers specifically, Southend-on-Sea in Essex, England, leads at 1.3 miles (2.1 km).
What materials are typically used to build piers?
Traditional pier construction has relied on wood, timber, iron, and cast iron as the primary structural materials. The specific choice depends on the engineering era, the environmental demands of the site, and the intended load the structure must bear.
How does a pier differ from a bridge or a jetty?
A pier projects outward from the shore into open water and is designed to stay above the waterline, supported by vertical piles. Unlike a bridge that spans between two landmasses, a pier's primary role is to provide access to the water itself rather than to cross from one side to the other.
