Barkhamsted is a small town in Northern Connecticut, best know for its eponymous reservoir. The creation of the reservoir and the Saville Dam in the 1940s provides some interesting hikes for road historians: a flooded town at Barkhamsted Hollow, and old alignments of routes 20, 179, and 181. See the Abandoned Highways page for details and locations.
Barkhamsted roads offer great scenery from the car, as well: routes 181, 219, and 318 have segments on the state's Scenic Road system.
In the mid-20th century, a freeway was planned for US 44 through Barkhamsted; no such plan is active today.
