Route description
Route 289 begins at an intersection with Route 87 north of the town center of Lebanon. It heads north and northeast for about 4.3 miles (6.9 km) through rural areas to the Windham town line.

History
In 1922, the Lebanon-Willimantic route was designated as a state highway known as Highway 214. In the 1932 state highway renumbering, Route 89 was established. It ran from Lebanon via Willimantic, Mansfield Center, Warrenville, and Westford up to Union and incorporated the entirety of old Highway 214. In 1964, Route 195 was extended south from Mansfield Center to Willimantic using part of Route 89, truncating the south end of Route 89. The former section of Route 89 south of Willimantic (old Highway 214) was renumbered to Route 289.
