  • Summary Old number for today's scenic Route 169.

Route 93 was commissioned in 1932, and followed today's Route 169, from Norwich into Massachusetts. It was changed to 169 in 1959, to avoid a numbering conflict in Massachusetts with Interstate 93.

Another route renumbered (partially) for the same reason: part of Route 190 became Route 168 in 1977 when Interstate 190 opened in Massachusetts.
