Interstate 393 is a spur freeway taking traffic from Interstate 93 and the state capital of Concord eastward to points east via U.S. 4 and 202. These two routes continue to Portsmouth and Rochester, respectively. The freeway bypasses Concord Municipal Airport (CON) and the commercialized corridor of NH 9 (former U.S. 4 & 202) to the north.
The designation of Interstate 393 was approved by AASHTO on July 13, 1976. The freeway initially ran east from the preexisting cloverleaf interchange between I-93 and the U.S. 3-4-202 connector to New Hampshire 9 (Loudon Road) in August 1981.1 The route was proposed to extend east from Concord to the Spaulding Turnpike in 1983, but that extension was dropped in favor of upgrading New Hampshire 101 to a full freeway between Interstates 93 and 95.2 That left construction of the eastern leg of I-393 east beyond NH 106 to open in December 1988.3

Perspective from Interstate 393 west
The western terminus of Interstate 393 receives no Exit number. This photograph shows the guide signage at the Interstate 393 & U.S. 202 split with U.S. 4 west onto Interstate 93 north. U.S. 4 overlaps with Interstate 93 northward for two exits, where it departs via Exit 17 to Andover. Photo taken 06/27/05.
Interstate 393 & U.S. 202 westbound at the southbound loop ramp onto Interstate 89 south. The full-cloverleaf interchange is only four miles north of Interstate 89 and thus includes the Interstate 89 control city of Lebanon. Photo taken 06/27/05.
U.S. 202 continues the Interstate 393 freeway to the traffic light with Commercial Street. Commercial Street links both sides of the freeway with Constitution Avenue to the east and New Hampshire Technical Institute. Photo taken 06/27/05.
Interstate 393 & U.S. 202 pass over an abandoned railroad line ahead of the freeway end at U.S. 3 (North Main Street). U.S. 202 southbound joins U.S. 3 for a one mile overlap through downtown Concord. U.S. 3 northbound heads toward the Penacook section of Concord from U.S. 202. Photo taken 06/27/05.

A look at the former reassurance sign posted for Interstate 393 & U.S. 4-202 at the freeway beginning from North Main Street (U.S. 3). U.S. 4 actually does not enter Interstate 393 until east of the Interstate 93 interchange. The sign was removed without a replacement by 2005. Photo taken by Dan Moraseski (10/00).
A set of traffic lights reside at the Commercial Street intersection with Interstate 393 & U.S. 202 between U.S. 3 and Interstate 93. A jersey barrier prevents cross traffic. Photo taken 06/27/05.
The exit to Interstate 93 southbound toward downtown Concord, Manchester, and Boston departs Interstate 393 east & U.S. 202 north after the Commercial Street intersection. The ramp also serves Stickney Avenue southbound. Interstate 93 meets the southern terminus of Interstate 89 and the F.E. Everett Turnpike four miles to the south. Photo taken 06/27/05.
The one-quarter mile guide sign for the loop ramp onto Interstate 93 north & U.S. 4 west posted on Interstate 393 east & U.S. 202 north. A 2005 sign replacement includes metric units on many of the Concord area freeway guide signs. Interstate 93 & U.S. 4 travel north toward Boscawen before splitting. Plymouth lies 40 miles to the north along the freeway otherwise. Photo taken 06/27/05.
Interstate 393 & U.S. 202 gain U.S. 4 eastbound at the Interstate 93 under crossing. A full-cloverleaf interchange facilitates the movements between the two freeways. U.S. 4 & 202 overlap with Interstate 393 through to the eastern terminus. Photo taken 06/27/05.
Perspective from Interstate 93 north
Leaving the Exit 13 partial-cloverleaf interchange with U.S. 3 (Manchester Street) on Interstate 93 northbound in Concord. Pictured here is the one-half mile sign bridge for Exit 14 (New Hampshire 9). Pull through panels posted along Interstate 93 in the Concord area feature shields for either Interstate 89 or 393 consistently. New Hampshire 9 (Bridge Street / Loudon Road) meanwhile travels east from downtown Concord to Steeplegate Mall and the east end of Interstate 393. Photo taken 06/27/05.
Interstate 93 continues north through the diamond interchange with New Hampshire 9 (Exit 14) to Interstate 393 & U.S. 4-202 (Exits 15E/W). Interstate 393 comprises an east-west spur between U.S. 3 (North Main Street) and U.S. 4 & 202 east of Concord. The freeway provides a quick departure for motorists bound for Rochester and Portsmouth along U.S. 202 north and U.S. 4 east respectively. Photo taken 06/27/05.
The previous set of overheads posted on Interstate 93 northbound at Exit 14. Traffic interests to Loudon should take Interstate 393 east to New Hampshire 106 north three miles from the freeway end. U.S. 202 southbound merges with U.S. 3 (North Main Street) at the west end of the freeway. Photo taken by Douglas Kerr (09/30/01).
Exit 15E departs Interstate 93 northbound for the Interstate 393 & U.S. 4 east and U.S. 202 north to Loudon, Chichester, and points east. U.S. 4 westbound merges onto Interstate 93 northbound for a 5.5-mile overlap to Exit 17 (Holt Road). Photo taken 06/27/05.
Perspective from Interstate 93 south
Merging onto Interstate 93 south & U.S. 4 east from Portsmouth Street (Exit 16) north of Concord. Attached to the Portsmouth Street overpass is the one-mile overhead for Interstate 393 & U.S. 202 (Exit 15). Photo taken 06/27/05.
Exit 15W leaves Interstate 93 south & U.S. 4 east for U.S. 202 south to U.S. 3 (North Main Street) and downtown Concord. The Interstate 393 freeway ends at North Main Street just west of Interstate 93. Photo taken 06/27/05.
U.S. 4 parts ways with Interstate 93 southbound via the Exit 15E loop ramp onto Interstate 393 east & U.S. 202 north. The three routes continue east with interchanges for New Hampshire Technical Institute, New Hampshire 132 (East Side Drive), and New Hampshire 106 (Sheep Davis Drive). Photo taken 06/27/05.

U.S. 4 & New Hampshire 9 east and U.S. 202 northbound leave Interstate 393 on the six mile drive to New Hampshire 28 near Gossville.

Photo taken 06/27/05.
Perspective from U.S. 4 & 202 and New Hampshire 9 west
Four sets of sign herald the Interstate 393 beginning along U.S. 4 & New Hampshire 9 and U.S. 202 south (Dover Road). The first sign indicates the direct connection with the Concord area Interstates 89 and 93. New Hampshire 9 (Loudon Road) also meets Interstate 93, but along a much slower drive through the eastern suburbs. Photo taken 06/27/05.
A diagrammatic overhead indicates the wye interchange split of Interstate 393 & U.S. 4-202 from New Hampshire 9. Interstate 393 & U.S. 4-202 continue west together to Interstate 93. New Hampshire 9 turns southwest toward Steeplegate Mall and Concord Municipal Airport. Photo taken 06/27/05.
The westbound beginning of Interstate 393 departs New Hampshire 9 (Dover Road) ahead of the junction with New Hampshire 106 (Sheep Davis Road). Both the freeway and Loudon Road interchange with Sheep Davis Road ahead. New Hampshire 9 otherwise continues to the Concord Heights Business District. Interests to downtown Concord should take Interstate 393 west to either Interstate 93 south or U.S. 3 (North Main Street) south. Photo taken 06/27/05.
New Hampshire uses small guide signs in place of stand-alone shields as reassurance markers on most freeways and surface highways. Pictured here is the first Interstate 393 shield posted after the split with New Hampshire 9 (Loudon Road). Photo taken by Jeff Royston (12/02).
