18th Avenue follows the old road from New Utrecht to Flatbush.
Forgotten New York identifies 18th Avenue with the old Road from New Utrecht to Flatbush, and part of it with the colonial Kings Highway, where a milestone was placed in 1741; a granite copy now marks the spot. In 1987 the avenue also became Cristoforo Colombo Boulevard, from 60th Street to Shore Road. In 2008 Forgotten New York placed Bensonhurst's heaviest Italian section between about 60th and 75th Streets along 18th and parallel avenues.
