A dramatic new steel footbridge was completed in 2019 to improve access at the popular Tintagel Castle heritage site on clifftops in Cornwall, UK. The Anglo-Belgian design team was selected from 137 entrants in an international design competition. They describe in this paper how the unique cantilevered arch design was developed for this archaeologically sensitive site, with no direct access by road or sea and an aggressive marine environment. The two halves of the superstructure were built from 14 sections using a cable crane, leaving a symbolically important visual gap at its slender midspan. The award-winning bridge has become a tourist attraction in its own right, and the castle now has the highest visitor experience score of all of English Heritage’s 300-plus historic sites.

英国康沃尔廷塔杰尔城堡人行桥的设计与施工

一座引人注目的新钢人行天桥于 2019 年完工，以改善英国康沃尔悬崖顶上广受欢迎的廷塔杰尔城堡遗址的交通。盎格鲁-比利时设计团队从 137 名参加国际设计竞赛的参赛者中脱颖而出。他们在本文中描述了独特的悬臂式拱门设计是如何为这个考古敏感的地点开发的，没有直接的公路或海上通道，而且海洋环境充满侵略性。上部结构的两半由 14 个部分使用电缆起重机建造而成，在其细长的中跨处留下了一个具有象征意义的视觉间隙。这座屡获殊荣的桥梁本身已成为一个旅游景点，这座城堡现在是英国遗产 300 多个历史遗迹中游客体验得分最高的。
