Dual carriageway [SEP] History
A very early (perhaps the first) example of a dual carriageway was the "Via Portuensis", built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of the Tiber. One claim for the first divided highway in the United States was Savery Avenue in Carver, Massachusetts, first built in 1860, where the two roadways were separated by a narrow strip of trees down the middle. In 1907 the Long Island Motor Parkway opened, and roughly 20% of it featured a semi-dual-carriageway design. The New York City Belt Parkway system, which was built between 1907 and 1934, also pioneered the same design.
