The New York State Office of Parks, Recreation and Historic Preservation (OPRHP) has unveiled the design of the new Sentry Bridge at Watkins Glen State Park, designed by schlaich bergermann partner (sbp) and Snøhetta. Set to replace a 1908 concrete arch bridge, the new structure reflects over a century of pedestrian infrastructure, from tunnels to lookouts, along the popular Gorge Trail.

This redesigned Sentry Bridge maintains a connection to the original arch structure while offering a modern, lightweight aesthetic. Stretching 46 feet, the bridge’s stainless-steel construction is anchored by the stronger rock face on the gorge’s north side, with a half-arch design that subtly disappears behind the rocks, inviting visitors into the scenic Gorge Trail. Materials including stainless steel, bronze, concrete, wood, and local stone seek to highlight both craftsmanship and durability, embracing the elements to become part of the gorge’s natural and historical landscape.

The replacement is due to structural compromises observed in the original bridge’s abutments. After a 2022 inspection revealed severe erosion and stability issues, OPRHP and the design team opted for a solution that transfers the bridge’s load to the more stable northern abutment. In case of further degradation, the bridge can function as a cantilever, with support solely on the north side.

“Watkins Glen is a place for the senses,” Alan Gordon, Architect, and Snøhetta’s Partner-in-Charge said about the project. “Its storied paths welcome adventurers of all ages to move through woodland stillness and into the roar of rushing water. The new Sentry Bridge will bring these experiences into focus. Careful material transitions will emphasize temperature, texture, and touch at the detail level, and visitors can look forward to stepping from a lofty cantilever to ancient bedrock, beginning their journey up the historic Gorge Trail.”

The project includes improvements to user access, such as renovating the north and spiral tunnels and reconfiguring the southern bridge landing. Additionally, an indirect lighting plan will illuminate the bridge’s silhouette, enhancing its visual impact. To minimize environmental disturbance, the bridge will be prefabricated off-site and installed as a single piece, shortening construction time and reducing the Gorge Trail’s closure. 

Demolition of the old bridge and installation of the new Sentry Bridge will begin in summer 2025, with completion targeted by July 4, 2026.
