The Four US 70's of Selma & Smithfield

One of the more unique set-ups for US 70 within North Carolina, and the entire country, is the four different versions of US 70 that serve the Johnston County towns of Selma and Smithfield.  Although at times very confusing to even the local driver, US 70, US 70A, US 70 Business, and US 70 By-Pass each have a specific link to the evolution of US 70 through this area.



Original Routing: When US 70 was established in 1926, the highway designation followed the original route of the Central Highway through the area.  It would pass to the south of Pine Level and into Smithfield.  (Map source: 1927 Clason's. Courtesy: Mike Roberson)

1928 - Mid 1950s:  For nearly three decades, US 70 traversed west from Princeton, then along today's US 70A through Pine Level, to Selma, before heading south on US 301 towards Smithfield.  In Smithfield, US 70 then left US 301 to head towards Clayton and Raleigh along what is now US 70 Business.  (Map source: 1939 NC Official).
Mid 1950s - 1972:  A new alignment for US 70 opened to the south from Princeton to Smithfield.  The original US 70 through Pine Level to Selma was renamed US 70A, which it is still called today.  It is not known it US 70A West would be signed along US 301 South to US 70 in Smithfield.  The dashed line in the 1958 General Drafting Map is for a then under construction Interstate 95.  Both US 70 and US 70A would have interchanges with the new highway.

1973-1991:  US 70A would be extended westwards over secondary roads to meet US 70 just beyond Wilson's Mills.  As traffic increased on both routes within Smithfield and near the I-95 interchanges, the state would begin to widen US 70A from Wilson's Mills to I-95 and US 70 from Smithfield towards Princeton.  At the same time, a new four lane highway was being built from US 70A's interchange with I-95 to US 70 a few miles east of I-95.  (Map Source: 1973-74 NC Official).

1991-1998: With the completion of a new four lane highway from US 70A at I-95 to US 70 four miles east of I-95, US 70 was realigned and split into three different routes.  US 70 now was moved onto what was the 1973 extension of US 70A from Wilson's Mills to I-95.  It then followed the new alignment to a widened US 70 seven miles west of Princeton.  The US 70 that traveled from Wilson's Mills through Smithfield was redesignated US 70 Business.  US 70A was truncated from Wilson's Mills to US 70 just east of its interchange with I-95.  US 70 was widened in Wilson's Mills in 1993.  (Map source: 1992-93 NC Official)

1998 - Today: Heavy traffic was still an issue with US 70 specifically at US 301 and its interchange with I-95 (Exit 97).  As a result, the state built a freeway bypass of the congested area in 1998.  The freeway begins one mile west of US 301 and rejoins US 70 one mile east of I-95.  This new freeway was deemed US 70.  After the new highway's opening, US 70 through Selma was renamed US 70 Business; but because of confusion with US 70 Business through Smithfield two miles to the south, it was quickly renamed back to US 70 with the new highway gaining the By-pass banner.  By-Pass US 70 does not have an interchange with Interstate 95.  Access to the interstate is possible from US 70 by either exits 336 or 334.  (Map Source: 2004 NC Official).

Coming Soon: With the approval of an Interstate from Clayton to Morehead City, Interstate 42 will be routed along what is currently US 70 By-Pass through the area.  It will also run along regular US 70 to the immediate east and west.  Interestingly, there are no current plans to connect Interstate 42 to its north-south counterpart - Interstate 95. Traffic will continue to use the current US 70 connection through Selma to connect between the two interstate.  So soon a new chapter in the area's colorful highway history is set to begin.


US 70 By-Pass splits from US 70 East (Exit 334) just outside of Selma.  Although a freeway, US 70 By-Pass does not have any direct access to Interstate 95.  Access to the Interstate is available via US 70.  Interstate 42 will follow US 70 By-Pass.  (Photo Taken by Brian LeBlanc)

A look at the US 70/US 301 intersection from US 301 North.  This heavily congested intersection was one of the reasons the US 70 By-Pass was built in the late 90s.  This also is the southern terminus of NC 39, for a brief time in the 1990s, NC 39 South would continue on US 70 East to end at I-95.  (Photo taken by Brian LeBlanc)

    Old US 101; the San Juan Grade

    While researching maps for California State Route 183 I noticed something interesting on the 1935 County Highway maps for San Benito and Monterey County.  From what it appeared it seems that there used to be a state highway running from US 101 south on San Juan Highway, through San Juan Bautista, south over the San Juan Grade to Salinas.  It turns out what I discovered was an a very old alignment of US 101 which was replaced by 1932.

    The information relevant to the history of US 101 over the San Juan Grade is as follows:

    -  The San Juan Grade was built in 1915 which presumably replaced Old Stage Road from Salinas to San Juan Bautista.  Presumably this was part of alignment adopted as Legislative Route 2 from San Francisco south to San Diego in 1909.  This history can be seen on 1931 edition of the California Highways and Public Works Journal and on

    -  By 1926 the San Juan Grade became part of US 101.  The San Jua…

    The Tioga Pass Road

    Last Summer the Tioga Pass Road over the Sierras in Yosemite National Park opened late due to the heavy snow pack during the previous winter.  Approaching the start of July the Park Service finally had cleared Tioga Pass, I headed up shortly after the 4th of July holiday during a lull in the tourist season.

    The Tioga Pass Road runs from the Big Oak Flat Road east to US Route 395.  The Tioga Pass road is largely within the boundary of Yosemite National Park but is also partially on California State Route 120 east of the Tioga Pass entry station to US 395.  The Park Service maintained portion of the Tioga Pass Road serve as a implied connection between the two segments of CA 120.  The Tioga Pass Road is the highest road mountain pass in California with Tioga Pass which lies at 9,945 feet above sea level.

    The Tioga Pass Road is very old with the eastern section up Lee Vining Canyon to the Tioga Mine being built in 1883.  The connecting section of the Tioga Pass Road from Big Oak Flat R…

    California State Route 49, The Golden Chain Highway (CA 16 north over Yuba Pass to CA 89)

    After completing California State Route 124 I took CA 16 to the eastern terminus to start my first Trans-Sierra route; California State Route 49/Golden Chain Highway over Yuba Pass.

    As stated I joined CA 49 from the eastern terminus of CA 16 in Amador County.  CA 49 actually begins in Madera County to the south in Oakhurst at CA 41.  CA 49 is about 295 miles long and travels most of the traditional 1849 Gold Rush Country north from Oakhurst to CA 70.  If you want history and old towns then CA 49 is one of the best routes on the West Coast to see both.

    To the north of CA 16 the next major junction is Signed County Route E16 in Plymouth which is on Shenandoah Road.  E16 is a 33.2 mile route which travels northeast to US 50. 

    Plymouth dates back to the 1850s and is mostly known for a winery that dates back to 1856.  These photos are from Main Street looking west.

    CA 49 generally is very rural and doesn't deviate much from when it was first signed back in 1934.  While CA 49 isn'…
