On April 6, 2001, the reconstructed wooden footbridge was opened, being the longest wooden bridge in Switzerland. The Kapellbrücke is a 204-metre-long (669 ft) bridge crossing the Reuss in the city of Lucerne in Switzerland. It is the oldest wooden covered bridge in Europe, and one of Switzerland's main tourist attractions. [citation needed]
The bridge opened for highway M-26 traffic in 1990, at which point the neighboring Lake Shore Drive Bridge was restricted to pedestrian use. [4] On August 26, 1992, the bridge was entered into the 1992 Timber Bridge Design and Construction Award Competition. [5] It was awarded first place in the "Long Span Vehicular Bridges" category. [6]
The earliest bridges in North America were made of wood, which was abundant and cheaper than stone or masonry. Early wooden bridges were usually of the Towne lattice truss or Burr truss design. Some later bridges were McCallum trusses (a modification of the Burr truss). About 1840, iron rods were added to wooden bridges.

Although large bridges of wooden construction existed in China at the time of the Warring States period, the oldest surviving stone bridge in China is the Zhaozhou Bridge, built from 595 to 605 AD during the Sui dynasty. This bridge is also historically significant as it is the world's oldest open-spandrel stone segmental arch bridge.
In the end of the 20th century three-hinged arches made a comeback associated with the uses of engineered wood ("glulam") in bridge construction: [7] the glulam construction have to be pre-fabricated, using three-hinged design naturally divides the arch into two halves that are easier to transport.

A timber bridge or wooden bridge is a bridge that uses timber or wood as its principal structural material. One of the first forms of bridge, those of timber have been used since ancient times. Wooden bridges could be a deck-only structure or a deck with a roof. Wooden bridges were often a single span, but could be of multiple spans.
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. [1] The purpose of the covering is to protect the wooden structural members from the weather.
