Major Freight Corridors in New Hampshire
I-93: Nashua to Manchester to Concord to Vermont Border
New Hampshire's primary north-south corridor — the direct connection between Boston and New Hampshire markets. The Nashua-to-Manchester corridor has significant commercial traffic driven by Boston overflow distribution. North of Concord, traffic drops substantially and conditions are more rural.
I-89: Concord to Vermont Border
West-northwest connector from Concord to the Vermont border at Lebanon/West Lebanon. Primarily consumer goods, tourism supply, and construction materials. Lower commercial volume than I-93.
US-1: Portsmouth Coastal Corridor
The coastal route running through Portsmouth — the primary seacoast city. Portsmouth's historic downtown creates delivery complexity for local commercial vehicles. Route 1 also accesses Maine's border markets.
What Drives Truck Insurance Costs in New Hampshire
- Boston overflow distribution: Nashua and Manchester have become significant distribution locations for operations serving Boston without paying Boston metro insurance rates. Amazon, FedEx, and UPS have major sort facilities in southern New Hampshire.
- Lumber and construction materials: New Hampshire's North Country forests generate lumber freight. Resort development in the White Mountains creates ongoing construction materials demand.
- Tourism supply chain: Ski resorts (Waterville Valley, Cannon Mountain, Loon) require year-round supply deliveries with highest demand in ski season.
- Moderate litigation: New Hampshire courts are significantly more defense-favorable than Massachusetts — a major driver of NH's cost advantage.
