New Hampshire Route 1A is an 18.32-mile (29.48 km) long state highway located in southeast New Hampshire.

In Portsmouth, it is known as Miller Avenue and Sagamore Avenue.

Route description

Older-style NH 1A shield, still prominent on signs.

NH 1A begins at the state border between Seabrook and Salisbury, Massachusetts. Just 50 yards (46 m) from the state line, NH 1A meets the eastern end of NH 286, an extension of Massachusetts Route 286, a connector to US 1 and Interstate 95 in Salisbury. NH 1A proceeds north, passing east of Hampton Harbor into Hampton Beach. It is on Hampton Beach where NH 101 meets its eastern end at NH 1A as a single-lane alleyway in each direction (Church Street northbound, Highland Avenue southbound). NH 1A continues as a four-lane divided highway running directly next to the coastline beaches. Just north of an intersection with Winnacunnet Road, NH 1A narrows back to a two-lane undivided highway, and then meets the eastern end of NH 27. The road continues another mile or so, crossing into North Hampton, and meets the eastern end of NH 111. NH 1A proceeds north out of North Hampton and along the coastline past Rye Beach, Rye North Beach, Wallis Sands, and Odiorne Point State Park, where it turns west, away from the ocean. The road turns back north at the intersection known as Foyes Corner and enters the Portsmouth city limits, passing the southern end of NH 1B (a connector to New Castle). NH 1A continues towards downtown Portsmouth, where it ends at the intersection of Miller Avenue and Middle Street (US 1).
