Canton Viaduct is a blind arcade cavity wall in Canton, Massachusetts, built in 1834–35 for the Boston and Providence Railroad.
At its completion, it was the longest (615 ft [187 m]) and tallest (70 ft [21 m]) railroad viaduct in the world; today, it is the last surviving viaduct of its kind. It has been in continuous service for 189 years; it now carries high-speed passenger and freight rail service. It supports a train deck about 65 feet (20 m) above the Canton River that passes through six semi-circular portals.
The Canton Viaduct was the final link built for the B&P's then 41-mile (66 km) mainline between Boston, Massachusetts and Providence, Rhode Island. Today, the viaduct serves Amtrak's Northeast Corridor, as well as Massachusetts Bay Transportation Authority (MBTA) Providence/Stoughton Line commuter trains. It is located 0.3 miles (0.48 km) south of Canton Junction, at milepost 213.74 (at the north end of the viaduct) reckoned from Pennsylvania Station in New York City.
