 NY 8 originally extended eastward from Hague to a ferry across Lake Champlain at Putnam when it was assigned as part of the renumbering. In between the two locations, the route utilized modern NY 9N, Montcalm Street, NY 22, and Wrights Ferry and Wrights roads. It was realigned in the early 1930s to continue east from Ticonderoga on what is now NY 74 to another ferry across the lake. NY 8 was altered again c. 1934 to follow NY 22 north from Ticonderoga to Crown Point, where it turned off the highway onto Bridge Road (now NY 185). Route 8 remained intact along this routing until c. 1968, when Route 8 was truncated southwestward to NY 9N in Hague.
