Bow Bridge, Central Park: A Historic Restoration with a Sustainable Future
New York City’s Central Park is renowned as one of the world’s most famous urban landscapes and few spots capture its beauty and charm quite like Central Park’s Bow Bridge. Spanning 87 feet across The Lake—one of the park’s most picturesque bodies of water, linking the Ramble on the east to Cherry Hill on the west—the bridge was first constructed in 1860. With its graceful cast-iron curves, intricate detailing, and sweeping skyline views, the Bow Bridge is an architectural marvel of its time and one of the most photographed and iconic pedestrian bridges in the world.
After more than 160 years of enduring weather extremes, heavy foot traffic, and countless film productions, the bridge showed clear signs of wear. While it underwent a comprehensive restoration in 2015, by 2024, the Southern Yellow Pine decking required replacement. For this essential upgrade, Accoya emerged as the optimal solution—its exceptional dimensional stability ensures the wood retains its shape and structural integrity without warping, cupping, or swelling, even under New York’s intense seasonal fluctuations. In addition to its superior performance, Accoya’s sourcing from sustainably managed forests and its minimal environmental impact made it a natural fit for the Central Park Conservancy and New York City Parks, aligning with their long-standing commitment to ecological stewardship.
The Central Park Conservancy discovered Accoya online while researching sustainable wood that possessed the desired characteristics—most importantly, the flexibility required due to the dramatic curvature of the deck, along with Accoya’s durability, resistance to rot, stability, and aesthetic appeal. They experimented with it and other modified wood materials throughout the park, believing Accoya to be the most suitable option for the new decking on Bow Bridge.
The decision to use Accoya was also driven by its FSC® certification and its ability to be milled into precise sizes, which helps maintain the historical accuracy of the bridge while enhancing its aesthetic appeal. While expected to provide cost savings over its service life, it’s too early to assess this material benefit but the aesthetic improvement is significant, and its stability already evident, contributing to the good functionality of the bridge’s drainage systems. Overall, the experience of working with the material and its supplier, Rex Lumber, was smooth and seamless.
The restoration of the Bow Bridge deck has revitalized this historic gem. Using Accoya, the bridge exemplifies how timeless design and modern innovation can coexist in perfect harmony.
Accoya was also used in the restoration of the 19th-century Gothic Bridge, located further north near 94th Street, where it spans the bridle path just west of the Jacqueline Kennedy Onassis Reservoir and the one-way track loop. Although it may not be as famous, the bridge is a much-loved feature of the park. The use of Accoya on a second bridge highlights its growing reputation as a trusted choice for preserving New York’s architectural heritage with integrity and care.
