U.S. Highway 70 Bypass
Location	Selma, North Carolina
Length	2.8 mi[22] (4.5 km)

Established in July 1997, US 70 Bypass is part of a rare oddity known as the four US 70s of Selma-Smithfield: US 70, US 70A, US 70 Business, and US 70 Bypass.

In the center of town, it starts running concurrently with U.S. Route 271 Business until they both end outside of Hugo at an interchange with the Indian Nation Turnpike, U.S. Route 271 and US 70. The route was decommissioned in 2019 to eliminate highway traffic from passing through Hugo.

The entire route is in Choctaw County.

U.S. Highway 70C
Location	Benton, Arkansas
Existed	May 13, 1959[34]–January 23, 1974[35]

U.S. Route 70C (US 70C, the "C" for "City", i.e., a business loop) formerly ran between what is now Interstate 30 (I-30) exits 116 (Sevier & South Streets) and 118 (Congo Road) in Benton, Arkansas. Though it was largely the result of a rerouting of US 70 and US 67 from Little Rock around downtown Benton in 1955, most of which later became I-30, it was not created until 1959 after US 70 was further rerouted between Benton and Hot Springs.^[34]

History

Since the place where US 67 and US 70 separated was moved by both reroutings—first in 1955 from downtown Benton to present-day I-30 exit 117 (AR 5/AR 35) just north of downtown where the new route crossed old US 70 (now AR 5 north of I-30 and AR 35 south of it), then in 1959 to present-day I-30 exit 111 (Arkansas Health Center) near Haskell—most of US 70C was actually the pre-1955 route of US 67, of which only present-day Military Road north of AR 35 was also the pre-1955 route of US 70.^[36] The only exception was at the eastern end; since there was no interchange where the pre-1955 US 67/US 70 route crossed I-30 just outside Benton, US 70C used Congo Road from Military Road to present-day I-30 Exit 118.

When the rerouted US 67/US 70 was formally designated as I-30 in 1960, US 70C also became Benton's I-30 business loop. Both loops were decommissioned by 1975.^[36] The entire route was taken over by the City of Benton, except for a short section of Military Road added to AR 88 to connect it with AR 35.^[35]

U.S. Highway 70B
Location	Little Rock, Arkansas to North Little Rock, Arkansas
Existed	c. 1976–c. 2006

The segment of present U.S. 70 from where it leaves Interstate 30 at Exit 132 (University Avenue) in Little Rock, Arkansas, to I-30 Exit 141B (Broadway) in North Little Rock, was signed as U.S. 70B from the mid-1970s to the mid-2000s. It was previously the route of U.S. 70 as well as U.S. 67; it was also the I-30 Little Rock business loop until that route was deleted earlier in the 1970s.

Before U.S. 70B was created, U.S. 70 ran concurrently with I-30 from Exit 111 (Hot Springs) near Haskell to Exit 132, as it does today. Its U.S. 67 concurrency fell between two different U.S. 67 concurrencies with I-30; one (shared with U.S. 70) was from Exit 114 (then Arkansas State Hospital, now Arkansas Health Center) near Haskell to Exit 132, while the other (shared with U.S. 65 & 167) was from Exit 141B to the end of I-30 at Exit 143B (I-40), also in North Little Rock.

While U.S. 70B was active, U.S. 70 continued its concurrency with I-30 past Exit 132 to Exit 141B, where it returned to its original route. U.S. 67 also moved to I-30 when U.S. 70B was created, thus making its concurrency with I-30 continuous from Exit 114 to the end of I-30. Both concurrencies were shared with U.S. 65 & 167 beginning at Exit 138B (Pine Bluff-El Dorado, now the beginning of Interstate 530). However, many Arkansas state highway maps continued to show U.S. 70B as U.S. 67 & 70, and sometimes even as the I-30 business loop (years after it was officially deleted).

Although I-30 signs at Exit 132 still refer to University Avenue as U.S. 70B and claim U.S. 70 East continues on I-30 East, and I-30 signs at Exit 141B refer only to U.S. 70 East (U.S. 70 West formerly joined I-30 West at that exit), all signs on the business loop were changed back to U.S. 70 in the mid-2000s, thus officially truncating U.S. 70's concurrency with I-30 at Exit 132. U.S. 67 did not return to this route; it remains concurrent with I-30 from Exit 114 (and U.S. 65 & 167 from Exit 138B) to the end of I-30.

U.S. Highway 70 Business
Location	Beaufort, North Carolina
Length	3.3 mi[37] (5.3 km)
Existed	June 2018–October 2019

U.S. Route 70 Business (US 70 Bus.) was the designation of secondary roads that mostly follow along the former US 70 route through downtown Beaufort. The routing in question ran south along Turner Street (SR 1174) then east on Cedar Street (SR 1493) and transitions onto Live Oak Street as it goes northeasterly before reconnecting with US 70.^[38] Signage of US 70 Bus. possibly appeared soon after the mainline US 70 rerouting on new bypass route north of Beaufort in January 2018, confirmed with Google Street View imagery from July 2018.^[39] The routing does not exist on NCDOT mapping/records nor was it submitted to AASHTO for approval.^[40] The road was decommissioned in October 2019 and was given to the city of Beaufort.^[41]

U.S. Highway 70 Bypass
Location	Goldsboro–La Grange, NC
Length	21.7 mi (34.9 km)
Existed	May 2016–September 2024

U.S. Route 70 Bypass (US 70 By-pass) was an approximately 22.3-mile (35.9 km) controlled-access highway bypassing north of Goldsboro, connecting with US 70 west of Goldsboro and west of La Grange. It was approved by AASHTO on September 25, 2015, with its official establishment dependent on its completion; at the time, the current completed sections were temporarily signed as NC 44.^[42][43] On May 27, 2016, the last section, the eastern section from Wayne Memorial Drive to US 70 west of La Grange, was completed, and the road was officially renamed the US 70 Byp. The route was redesignated as part of Interstate 42 in September 2024.
