Canton Viaduct

The Canton Viaduct is a stone railway bridge in Canton, Massachusetts that extends 615 feet (187 meters) in length and rises 70 feet (21 meters) high. The structure consists of 42 deck arches made from granite blocks spanning the Canton River.

The viaduct was built in 1835 for the Boston and Providence Railroad, establishing the first rail connection between Boston and New York through Providence. Its innovative stone arch design set standards for railway bridge construction in North America.

The viaduct became a defining feature of the local landscape and played a central role in connecting the region to major cities by rail. Trains passing overhead remain a familiar part of daily life for residents.

The bridge can be viewed from nearby walking paths, with the best views from below the structure. Visitors should exercise caution since active railway tracks run beneath it and trains pass regularly.

Each granite block bears a mason's mark identifying the individual craftsman who shaped it, a rare example of personal accountability in 19th-century stonework. These markings allow visitors to trace the contributions of individual workers even today.
