Located about 15 miles from downtown Boston, Canton is home to just over 20,000 residents. The town is part of Norfolk County and the Greater Boston area. One point of interest in the town is the Canton Viaduct. It was built in 1835 and is one of the two oldest surviving multiple arch stone railroad bridges still in active mainline use in the United States. It has been in continuous use for over 185 years.
