U.S. Route 4 stretches across the heart of New Hampshire — from the Seacoast to the Vermont border, snaking past all kinds of villages, antique shops, roundabouts and historical markers in between. If you live in New Hampshire, you’ve probably been on it.

The road started as the state’s first turnpike, “extending 36 miles from [the] Piscataqua Bridge in Durham to the Merrimack River in East Concord,” according to a historical marker along Route 4 in Northwood. It’s since become one of the main thoroughfares connecting the east and western parts of the state.

But if you live or travel on this road, you know there’s much more to life along Route 4 than antique shops and roundabouts. And we want to hear from you.

What questions do you have about this stretch of highway - its landmarks, its businesses, or the communities it cuts through? If you live on Route 4, what do you think we should know about it?

We invite you to share your questions and stories using the forms below — and if you do, we might invite you to participate in one of our upcoming stories for this summer series.

Stay tuned for more reporting from Route 4 coming soon.
