The Liberty Hill neighborhood was the commercial center of town for most of the 19th century and into the 20th. Holding the town's post office, as well as two general stores, it was Lebanon's primary link to the larger Connecticut and New England communities. The area maintained its importance into the 1930s and 1940s. The greater availability of telephones in private residences, the improvement of roads and the introduction of highways, and the increase of personal cars for commuting to surrounding towns, all meant that individuals had less need to restrict themselves to close by conveniences. Liberty Hill nonetheless remains one of Lebanon's primary neighborhoods.
