Editing Interstate 93 (section)

===New Hampshire===
I-93 travels just over {{convert|131|mi|km}} in the Granite State, about two-thirds of the highway's total distance. Serving as the main Interstate route in New Hampshire, it connects the state capital, [[Concord, New Hampshire|Concord]], and its largest city, [[Manchester, New Hampshire|Manchester]]. Beyond Concord are the towns of [[Tilton, New Hampshire|Tilton]], [[Plymouth, New Hampshire|Plymouth]], and [[Littleton, New Hampshire|Littleton]]. I-93 is designated as the Alan B. Shepard Highway,<ref>{{cite web |url = http://www.bostonroads.com/roads/I-93S_NH/ |title = Alan B Shepard Highway (I-93) |access-date = September 25, 2014 }}</ref> from the Massachusetts line to [[Hooksett]] (just north of Manchester at the northern terminus of I-293), as the [[Everett Turnpike]] from Hooksett to Concord, and as the Styles Bridges Highway, after the [[Styles Bridges|US politician]], from Concord to the Vermont line. This section of roadway was constructed between 1961 and 1977.

Between the northern end of [[I-293]] in Hooksett and the beginning of [[I-89]] in [[Bow, New Hampshire|Bow]], I-93 also carries the northern end of the Everett Turnpike. There is one toll booth along this section, at exit&nbsp;11 in Hooksett; the toll for passenger cars is $1.00 ($0.50 at the ramp toll booth). This is the only toll collected along the entire length of the highway. I-93 in New Hampshire is also notable for having state liquor stores serve as rest areas, which are passed just after the toll plaza, traveling north. There are separate stores on both sides of the Interstate for travelers in each direction.

I-93 enters New Hampshire at [[Salem, New Hampshire|Salem]]. A rest area and welcome center is available on the northbound side of the freeway, directly before exit&nbsp;1. I-93 is four lanes wide in each direction for its first {{convert|18.5|mi|km}}, until the split with I-293 and [[New Hampshire Route 101]] (NH&nbsp;101), where I-93 drops to three lanes before adding a fourth and fifth lane back to the freeway after the interchange. The construction to widen I-93 to four lanes each way between the Massachusetts–New Hampshire border and its junction with I-293 and NH&nbsp;101 was fully complete as of April 2021.<ref>{{Cite web|title=Salem-Manchester 10418-C {{!}} Project Specific Information {{!}} Project Center |publisher = New Hampshire Department of Transportation|url=https://www.nh.gov/dot/projects/salem10418c/index.htm|access-date=April 29, 2021}}</ref>

I-93 and NH&nbsp;101 run concurrently for about {{convert|1|mi|km|spell=in}} before NH&nbsp;101 exits to the east as its own freeway, serving [[Portsmouth, New Hampshire|Portsmouth]] and the Seacoast Region. I-93 maintains three lanes of traffic in each direction until the junction with I-89, then is a four-lane freeway through most of its journey northward, with the only exception being the [[Franconia Notch]] section.

In the state capital of Concord, [[I-393]] heads directly east (cosigned with eastbound [[U.S. Route 4|US&nbsp;4]] and [[U.S. Route 202|US&nbsp;202]]), providing another route to the Seacoast Region. Westbound US&nbsp;4 joins I-93 and runs concurrently with it, crossing the [[Merrimack River]] again, until exit&nbsp;17 for [[Penacook]], about {{convert|5|mi|km|spell=in}} farther north, before exiting westward. Continuing north, I-93 traverses the [[Lakes Region (New Hampshire)|Lakes Region]] of New Hampshire and then makes its way north through the heart of the [[White Mountains Region]]. I-93 passes through [[Franconia Notch State Park]] as a [[two-lane freeway]] (one lane in each direction) with a {{convert|45|mph|km/h|adj=on}} speed limit, designed to reduce I-93's impact on Franconia Notch. For the trip through Franconia Notch, I-93 and US&nbsp;3 run concurrently.

Beyond Franconia Notch State Park, US&nbsp;3 heads northeastward through the [[Great North Woods Region (New Hampshire)|Great North Woods Region]], while I-93 runs to the northwest. The final town along I-93 in New Hampshire is Littleton, served by four exits. Many motorist services are available at exit&nbsp;42. After passing through town, it crosses the [[Connecticut River]] into [[Vermont]]. The last exit along I-93 is exit&nbsp;44 for [[Monroe, New Hampshire|Monroe]], through which a rest area and welcome center is accessible to travelers on both sides of the highway.

In 2013, a bill was signed by governor [[Maggie Hassan]] to raise the speed limit on I-93 to {{convert|70|mph|km/h|abbr=on}} from milemarker&nbsp;45 to the Vermont border, with the exception of the Franconia Notch Parkway. The new limit took effect on January 1, 2014.
