History

In the 19th century, the road connecting the villages of Clinton, Killingworth, and Higganum was a private turnpike known as the Killingworth and Haddam Turnpike. The turnpike was chartered in 1813 and collected tolls until 1850. In 1922, the length of the old turnpike was designated as a state road with designation State Highway 106. As part of the 1932 state highway renumbering, modern Route 81 was created from old Highway 106.^[2]
