Interstate 293
Interstate 293 (abbreviated I-293) is an long loop surrounding Manchester, New Hampshire, USA roughly shaped like two sides of a triangle. Completing the loop in the northeast (the third side of the triangle) is Interstate 93. The southern portion of the loop shares the road with NH 101 and passes near Manchester-Boston Regional Airport and the Mall of New Hampshire. The western portion of the loop shares the road with the Everett Turnpike, but there are no tolls on this portion of the turnpike.
==Route description==
Interstate 293 begins at a directional T interchange in the southeast of Manchester, where NH 101 West leaves I-93. I-293 is signed as a north–south road, but along the section concurrent with NH 101, the road travels in an entirely westerly direction. Exits 1 and 2 provide access to the Mall of New Hampshire area and the Manchester Airport respectively. After crossing the Merrimack River, I-293 enters the modified cloverleaf exit 3 interchange where I-293, NH 101, and the Everett Turnpike intersect. At exit 3, NH 101 leaves I-293 and continues west as a four-lane freeway to its junction with NH 114. I-293 makes a nearly 90-degree turn here, joining the Everett Turnpike and traveling north along the west bank of the Merrimack. The I-293/Everett Turnpike concurrency heads in to downtown Manchester, and is joined by NH 3A at exit 4. Exits 5 and 6 intersect local roads near bridges across the Merrimack, allowing travelers access to both east and west sides of Manchester. At exit 7, NH 3A leaves the concurrency, while I-293 and the Turnpike continue north to the end of I-293 at another interchange with I-93, just south of the Hooksett barrier toll plaza. From here I-93 and the Everett Turnpike are concurrent to the Turnpike's northern end in Concord.
As of June 16, 2008, the project to complete Exit 5 as a full interchange was complete. Drivers are now able to exit and enter Exit 5 both southbound and northbound. This exit is a single-point urban interchange (SPUI), the third in New Hampshire.
Like Interstate 393, the other secondary Interstate Highway in New Hampshire, I-293 is signed in concurrency with other routes along its entire length, and never runs alone other than on transition ramps between Route 101 and the Everett Turnpike. This is due to the I-293 designation having been added to already existing routes, Route 101 and the Everett Turnpike.
