the Everett Turnpike. History I-293 overlays portions of two earlier routes that were upgraded to provide the route an Interstate designation. NH 101 was the main east–west route across southern New Hampshire, connecting Keene with (at the time) Portsmouth, and passed through southern Manchester. The Everett Turnpike was an early toll highway connecting the three cities of the Merrimack Valley: Nashua, Manchester, and Concord. When it was accepted into the Interstate Highway System, the short NH 101 freeway from I-93 to the Everett Turnpike was numbered I-193 from 1961–1977. When I-93 was completed in 1977, the Everett Turnpike from NH 101 to I-93 was added to the route and it was renumbered as I-293. The NH 101 to Everett Turnpike interchange was later rebuilt to provide a free-flowing transition between the two legs.
