Chain Bridge, Federal cultural heritage bridge in Ostrov, Russia.

Chain Bridge is a 19th-century suspension bridge over the Velikaya River in Ostrov, Russia, supported by a system of metal chains that remain visible along its sides. It links the eastern and western parts of the city and is open to both pedestrians and vehicles.

The bridge was built between 1850 and 1853, at a time when suspension bridges were still a novelty in Russia. It quickly became a key route for trade and movement through Ostrov, shaping how the town grew around the river.

The chains that support the bridge are clearly visible from the walkway, giving it a look quite different from modern crossings. Locals use it as part of their daily routes along the river, and it serves as a natural meeting point in the center of Ostrov.

The bridge is easy to reach on foot from both sides of the city and can be crossed without any special preparation. In winter, the surface can become slippery, so wearing sturdy footwear is a good idea.

Unlike many protected historic bridges that become pedestrian-only monuments, this one still carries regular vehicle traffic alongside walkers. That makes it one of the few working 19th-century suspension bridges in Russia still used in everyday life.
