Paulinskill Viaduct, Railway viaduct in Hainesburg, United States.
The Paulinskill Viaduct is a concrete railway bridge with seven arches spanning 340 meters across Paulins Kill and standing 35 meters above the water. It was built to carry trains across the valley with a single-track design that served regional transportation needs.
The structure was completed in 1910 and initially held the title of world's largest reinforced concrete bridge before losing it the following year. It represented an ambitious railway expansion that aimed to connect distant communities.
The interior chambers hold layers of graffiti art left by visitors over time, creating an evolving record of those who have crossed the bridge. These markings reflect how the structure has become a canvas for personal expression.
The bridge is visible from nearby roads and accessible for photographs, particularly when viewed from below looking upward. The surrounding area is quite rural, so plan your visit with enough daylight and be ready for uneven ground.
Hidden inside the concrete arches is a complete network of maintenance passages and ladders allowing passage through the bridge's interior. This concealed system was engineered for inspections and repairs, but remains unknown to most visitors.
