Boardwalk in the context of "Boardwalk (entertainment district)"

A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges.

This is a list of boardwalks in the United States by state. Boardwalks can be found around the world, but they are especially common along the East Coast of the United States. One of the earliest and one of the busiest boardwalks was opened on June 26, 1870, in Atlantic City, New Jersey. Some pedestrian paths called "boardwalks" are made of concrete.Boardwalks border the beach's sand, and often contain many stores and attractions.

An esplanade or promenade is a long, open, level area, usually next to a river or large body of water, where people may walk. The historical definition of esplanade was a large, open, level area outside fortress or city walls to provide clear fields of fire for the fortress's guns. In modern usage, the space allows the area to be paved as a pedestrian walk; esplanades are often on sea fronts and allow walking whatever the state of the tide, without having to walk on the beach.

A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians. While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic.

For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be sustainable and easily constructed in such areas using only local materials and labor.

The Ubin–Khatib Important Bird Area, also known as the North-East Conservation Area , is an 8940 ha tract of largely undeveloped land in north-eastern Singapore on the border with the Malaysian state of Johor. It encompasses the island of Ubin and much of the islands of Tekong and Tekong Kechil, as well as a coastal strip of the main island, including the Lower Seletar Reservoir, with the intervening coastal waters, seagrass beds, mangroves and intertidal mudflats.
