New Hampshire Route 123 (abbreviated NH 123) is a 62.95-mile-long (101.31 km) secondary north–south state highway in southwestern New Hampshire. The southern terminus of the route is at the Massachusetts state line in Mason where, as Mason Road, the road continues as an unnumbered local road in the town of Townsend. The northern terminus, as signed, is at the Vermont border, where NH 123 continues west for a half-mile to U.S. Route 5 as Vermont Route 123. Route logs, however, place the terminus at New Hampshire Route 12 in Walpole.
In Walpole, NH 123 runs in a wrong-way concurrency with NH 12 north–south alongside the Connecticut River, the water body that represents the border between New Hampshire and Vermont. For the entire length of the NH 12/NH 123 concurrency, NH 123 South is, in reality, heading north on the compass while NH 123 North is traveling to the south.
In October 2005, heavy flooding in the New Hampshire area forced the closure of NH 123 in two different locations. The first was at the intersection of NH 123 and Cold River Road, approximately 5 miles (8 km) from the beginning of NH 123 in New Hampshire, where a bridge was destroyed from high water in the Cold River. The second closure was approximately 3 miles (5 km) south of New Hampshire Route 123A in the town of Alstead, where a section of roadway was completely washed away by the water. Both sections were subsequently rebuilt and reopened.
