The Four US 70's of Selma & Smithfield

Image
By
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.

Timeline:

 

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.

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)

    Bleriot Ferry - Alberta

    By
      Alberta operates six ferries scattered throughout the province. Roughly twenty to twenty-five kilometers up the Red Deer River from the town of Drumheller is one of the most scenic ferry crossings in all of Wild Rose Country, the Bleriot Ferry. Using the North Dinosaur Trail (Alberta Highway 838, or AB 838), the Bleriot Ferry provides a scenic river cruise of sorts in the Canadian Badlands. The Bleriot Ferry started operating in 1913 as the Munson Ferry when a few bridges crossed the Red Deer River. The ferry was started by Andre Bleriot, the brother of famed early aviator Louis Bleriot, who became famous for being the first person to fly over the English Channel. At the time, the Alberta provincial government commissioned local residents to run the ferries. There were several ferries along the Red Deer River, and not only did they serve as vital transportation links, but they also served as local social hubs, since everyone had to take the ferries to go places. Over time, as the...

    Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

    By
    In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

    I-73/I-74 and NC Future Interstates Year in Review 2024

    By
    Welcome to another annual review of progress in constructing North Carolina's New and Future Interstate routes. While 2024 was not too exciting, with no new segments of major routes opening, there was 1 new interstate signing, another proposed new interstate route, and the near opening of a new segment for 2 routes. As tradition, I will start off with a review of what happened with I-73 and I-74 and then move on to the major news of the year about the other new and future routes. Work continued on the I-73/I-74 Rockingham Bypass through the year. The last few months have been hoping for news of its opening before 2025, without luck. Signs of its near completion included the placement of new signs, many with interstate shields uncovered, along the Bypass and intersecting roadways. For example, these went up along US 74 East: Overhead signage at Business 74 exit which contains the future ramp to I-73 North/I-74 West. Signage was also updated heading west on US 74 approaching the unop...
