2026年7月30日，纽约州公园、游憩与历史保护办公室（OPRHP）正式揭幕沃特金斯格伦州立公园全新步行桥——Sentry Bridge。该桥梁由Snøhetta与schlaich bergermann partner（sbp）联合设计，在充分尊重场地历史文脉与自然景观的基础上，通过创新的设计理念与工程技术，为这座深受公众喜爱的公园地标赋予了新的诠释。

On July 30, 2026, the New York State Office of Parks, Recreation and Historic Preservation (OPRHP) unveiled the new Sentry Bridge at Watkins Glen State Park, a landmark gateway to one of New York's most iconic natural destinations. Designed by a team led by the New York-based studios of schlaich bergermann partner (sbp) and Snøhetta, the bridge reimagines a beloved park crossing through a design that balances engineering innovation with deep respect for the site's historic character and dramatic natural landscape.

漫步于沃特金斯格伦州立公园，仿佛置身于由峭壁、瀑布、幽潭与苔藓覆盖的溪流共同编织而成的自然秘境。Sentry Bridge坐落于公园主入口附近，是游客踏上峡谷步道后遇见的第一座桥梁。作为连接自然景观与游览体验的重要节点，它延续了公园步道基础设施建设的悠久传统，不仅构筑起通往峡谷的门户，也承载着对纽约州百年来公共建设成就的致敬，并寄托着对未来发展的美好展望。

Venturing through Watkins Glen State Park is a wondrous journey of cavernous rock walls, waterfalls, still pools, and mossy seeps. The new Sentry Bridge, designed by a team led by the New York-based studios of sbp and Snøhetta builds upon a legacy of trail structures within the beloved state park. The bridge marks the entrance to the gorge and commemorates one hundred years of past and future public works built by New York State Office of Parks, Recreation and Historic Preservation.

每年，超过一百万名游客沿着公园著名的峡谷步道探索这片壮丽的自然景观。作为进入峡谷的重要门户，桥梁及周边步道的更新不仅为访客开启游览体验，也为接下来的旅程奠定了探索与发现的基调。新桥取代了服役逾百年的原Sentry Bridge。此前的结构评估显示，长期风化侵蚀以及岩体稳定性问题已对桥梁造成严重损害。基于此，OPRHP委托Snøhetta与sbp共同设计一项永久性解决方案，在应对复杂工程挑战的同时，延续原桥承载的历史记忆与公众情感价值。

More than one million visitors traverse the park's famed Gorge Trail annually. As the point of entry into the gorge, the bridge and trail improvements both welcome and set a tone for adventure. The new bridge replaces the original Sentry Bridge, which served visitors for more than a century. Following inspections that identified structural deterioration caused by erosion and unstable rock conditions, OPRHP determined that a full replacement was necessary and commissioned sbp and Snøhetta to develop a permanent solution that honored the historic bridge while addressing the site's unique engineering challenges.

这座定制化不锈钢桥梁以悬挑结构跨越约14米宽的峡谷。桥体荷载完全由北侧岩层承担，该区域拥有更为稳定的基岩条件，能够满足结构支撑需求。桥梁采用半拱形设计语言，其轮廓巧妙地隐入南侧岩壁之中，在最大限度减少对自然景观视觉干预的同时，为瀑布、峭壁以及上方由美国平民保育团时期修建的峡谷步道提供了更加开阔的观景视野。

The custom-built stainless steel structure cantilevers 46 feet across the gorge. It bears entirely on the north side where the bedrock is stronger and able to support the load. The bridge's half-arch gesture recedes behind the southern rock face, expanding views of the waterfall, cliffs, and Civilian Conservation Corps (CCC)-era gorge trails above.

精湛的工艺是桥梁设计表达的重要组成部分。经过喷丸处理的不锈钢结构、黑槐木扶手、定制青铜铸件、采用粗锯铁杉模板浇筑而成的混凝土构件，以及全新的蓝石铺装平台，共同构成了桥梁丰富而克制的材料体系。每一种材料的选用都经过细致考量，不仅回应场地环境与气候条件，也兼顾触觉体验与长期耐久性，在自然与人工之间建立起细腻而持久的联系。

Craftsmanship is central to the bridge's character. The materials – a shot-peened stainless steel structure, black locust wood rails, custom bronze castings, concrete formed of rough sawn hemlock, and a new bluestone landing – were purposefully selected for their contextual, tactile, and durable nature.

桥上的定制青铜铸件将场地独特的自然与文化特征巧妙融入设计细节之中。濒危蜻蜓、珍稀植物以及历史拱桥模型等图案被融入其中，为访客创造近距离观察与触摸的机会，引导人们在驻足停留间发现沃特金斯格伦丰富的生态环境与深厚的历史积淀。

The bronze castings feature finer elements of the site. An endangered dragonfly, a rare plant, and a model of the historic arch bridge offer detailed, tactile moments to pause and examine the cultural and natural heritage of Watkins Glen.

与此同时，桥梁严格遵循纽约州公园系统百年耐久性的设计标准。这一长期使用目标深刻影响了从结构体系到材料选择的每一项设计决策，确保桥梁能够在未来持续服务公众，并从容应对时间与自然环境的考验。

The bridge also meets New York State Parks' rigorous 100-year durability requirements, a standard that shaped every material decision.

从体验层面来看，项目重新塑造了人与瀑布、岩层及峡谷地貌之间的关系。桥梁以精心构建的视线通廊引导人们望向下方景观，让水雾、光影与四季更迭成为旅程的一部分。穿越峡谷不再只是单纯的通行过程，而是一场与自然环境持续互动的沉浸式体验。

Experientially, the work frames views of the waterfalls and geology below, heightens awareness of the mist and shifting light, and creates a physical encounter with the landscape rather than  mere passage through it.

精心设计的材料过渡与触觉细节进一步强化了人与场地的联系，鼓励访客通过触摸、感知与停留，建立对环境更深层次的认识。定制黑槐木扶手以及受攀岩岩钉启发的锚固节点顺应岩壁与隧道的自然形态，在瀑布之后、隧道之间以及凿岩阶梯之上提供安全支撑的同时，也增强了探索过程中的沉浸感与动态体验。

Considered material transitions give visitors something to hold, something to feel, a direct connection to place. Custom black locust handrails and piton-inspired anchor points navigate the irregular surfaces of rock walls and tunnels to provide grip and tantalizing movement behind waterfalls, through tunnels, and up rock-hewn staircases.

通过建筑、工程、工艺与环境责任的深度融合，全新的Sentry Bridge延续了沃特金斯格伦长期以来以高品质公共基础设施连接人与自然的传统。在回应当代需求的同时，桥梁也传承着这片峡谷的历史记忆与场所精神，为这一享誉纽约州的自然地标开启新的篇章。

With its thoughtful integration of architecture, engineering, craftsmanship, and environmental stewardship, the new Sentry Bridge continues Watkins Glen's long tradition of connecting people to nature through carefully crafted public works.
