Hanover, NH → Buffalo, NY

The 336-mile drive from Hanover, New Hampshire to Buffalo, New York traces a compelling westward arc through the Northeast's varied landscape, taking approximately six hours and forty-three minutes of mostly highway driving. You'll begin by heading west on I-91 from Hanover, following the Connecticut River valley before merging onto I-89 near the Vermont-New Hampshire border. The route then carries you through upstate New York via I-87 (the Northway through the Adirondack region) and ultimately I-90 westbound, which takes you directly into Buffalo. This combination of interstates provides straightforward navigation, though you should anticipate moderate to heavy traffic as you approach the Buffalo metropolitan area in the final stretch.

Geographically, this drive showcases the dramatic shift from New England's high elevation to the broader, flatter terrain of western New York. You'll climb through the Green Mountains and into the Adirondacks, where elevations reach nearly 2,000 feet, then gradually descend as you push westward toward Lake Champlain and eventually the Finger Lakes region. Notable larger towns along your route include Glens Falls, New York, which sits at the southern edge of Adirondack Park, and Syracuse, where I-90 intersects I-81. The landscape transitions from dense forests and mountain ridges to more open agricultural lands and the eastern approach to the Great Lakes basin, offering visual variety throughout your journey.

You should be prepared for the urban congestion that characterizes the final 30 miles approaching Buffalo, particularly around the I-190 interchange and downtown approaches. The majority of the drive, however, flows smoothly through moderate to light traffic, especially during off-peak hours on weekdays. Spring through early fall represents the most pleasant time for this route, when roads are clear and the mountain scenery peaks in appeal. Winter driving demands extra caution, particularly through the Adirondack section where snow accumulation and elevation changes create hazardous conditions, while summer construction and occasional delays are typical on major interstates like I-90.
