Boardwalks

A boardwalk is a raised pedestrian walkway along a shoreline, typically constructed of wooden planks, that provides access to beaches and waterfront areas while protecting sensitive terrain from foot traffic. It can also span marshes or lakefronts and function as a promenade.

Construction and layout: Boardwalks are often built on piles or supports above the ground and may run parallel to the shore or connect piers. They vary in width and length and may include railings, viewing platforms, seating, and lighting. The surface is designed to withstand salt spray, weather, and heavy use.

Materials and design: Wood was traditional for early boardwalks; current boards use pressure-treated timber, tropical hardwoods, composite materials, concrete, or steel. Design must consider corrosion from salt, wind loads, drainage, and accessibility. Maintenance includes cleaning, sealing, replacing warped boards, and inspecting supports.

History and examples: The concept emerged during the 19th century as coastal resorts developed tourism infrastructure. Notable examples include the Atlantic City Boardwalk (opened 1870) and the Coney Island Boardwalk (developed in the late 19th to early 20th century). Across regions, boardwalks serve recreation, commerce, and access, often becoming iconic parts of coastal towns.

Environmental and economic aspects: Boardwalks help concentrate pedestrian traffic away from fragile dunes and wetlands but can alter local habitats. They are costly to build and maintain and are vulnerable to storms and erosion. They contribute to local economies through tourism and provide public accessibility to waterfront spaces.
