A new stainless-steel bridge has replaced a 1908 stone-clad arch span at Watkins Glen State Park in New York's Finger Lakes region, cantilevering 46 feet (14 metres) across a narrow gorge where a waterfall drops below. Schlaich Bergermann Partner (SBP), the Stuttgart-based engineering firm, served as project lead, with the architecture practice Snøhetta as design partner and New York State Parks, Recreation and Historic Preservation as the client (Dezeen, 4 August 2026).

The bridge marks the start of the Gorge Trail, a one-mile path threading past 19 waterfalls that opened for the 2026 season on 9 May. The old Sentry Bridge — a concrete arch structure clad in stone, built in 1908 — had decayed beyond straightforward repair. Snøhetta described the replacement, first announced in October 2024, as "a lightweight evolution" of that former arch (Snøhetta, 28 October 2024).

The engineering logic is blunt and site-driven. The north side of the gorge has stronger bedrock, so the stainless-steel structure is anchored there, fabricated locally and prefabricated off-site before being lifted into place by crane. From that anchor it reaches across to the other wall without a matching support — a cantilever, meaning the span is held from one side rather than resting on two. The half-arch form echoes the curve of the bridge it replaced, without replicating its bulk (SBP, 30 April 2026).

The finishes are quietly specific to the place. Black locust wood forms the handrails; the concrete was cast in rough-sawn hemlock formwork, leaving a wood-grain texture; bluestone paves the landing. Scattered through the site are custom bronze castings of local flora and fauna — an endangered dragonfly, a rare plant, and a miniature model of the historic arch bridge itself. SBP's managing director Michael Stein and Snøhetta project director Matt McMahon are both quoted on the project in the Dezeen report.

Construction had been scheduled to begin in July 2025 and finish by 4 July 2026, according to the New York State Council of Parks' annual report. SBP has since confirmed completion on its own newsroom page (SBP). The Gorge Trail typically closes in mid-October each year.

What makes the bridge worth noticing is how little it fights its setting. The gorge at Watkins Glen is narrow, wet and vertical — a difficult place to build anything without the structure announcing itself. The decision to anchor on the stronger north wall and reach across with a single steel half-arch keeps the intervention lean, and the bronze wildlife castings give visitors a reason to slow down at the point where the trail begins. For a park that draws crowds for its waterfalls rather than its infrastructure, the new Sentry Bridge does its job by drawing attention to the gorge rather than away from it.
