Travel directions
US 12 at Glenham.
US 12 in North Dakota comes from Hettingen and takes the first roughly 100 kilometers in South Dakota right along the border with North Dakota and only later bends south. At Mobridge, one crosses the Missouri River, after which the route heads east through the prairies. To the east, the population density increases somewhat and people pass through small towns more often. Aberdeen is a somewhat larger town, where one crosses US 281. From Aberdeen to Interstate 29, 120 kilometers to the east, US 12 is a 2×2 divided highway. East of I-29, US 12 is once again single-lane, passing Milbank and Big Stone City to the Minnesota border.

History
US 12 near Aberdeen.
US 12 was created in 1926 and ran through South Dakota from the start . The route has not been significantly modified in South Dakota since then. The route is particularly important in eastern South Dakota, west of Mobridge diminishes in importance due to the thinning road network west of the Missouri River. The bridge over Lake Oahe was probably built around 1950 when the dam at Pierre was built and the Missouri River was dammed to Lake Oahe.
Doubling Aberdeen – I-29
A 120-kilometer stretch from Aberdeen to I-29 has been widened to a 2×2 divided highway, mainly to make Aberdeen more accessible, as the place is far from motorways. Aberdeen is South Dakota’s third largest city.
Around 1994-1995 the first part of 25 kilometers between Aberdeen and Groton was widened to 2×2 lanes. Around 2003-2004, 34 kilometers between Groton and Bristol was doubled and around 2004, 15 kilometers between Webster and Waubay was also doubled. The 17km intermediate section between Bristol and Webster was doubled around 2005. About 2005-2006, the easternmost 20-mile section between Waubay and I-29 was widened to 2×2 lanes.
Traffic intensities
Every day, 600 vehicles pass the North Dakota border, descending to 400 vehicles east of Lemmon. This then gradually increases to 1,300 vehicles at Mobridge. Between Mobridge and Selby 1,900 vehicles and 1,200 to 1,900 vehicles ran to Ipswich, then rising to 4,400 vehicles on the west side of Aberdeen. From Aberdeen to I-29, 2,800 to 7,000 vehicles and 1,700 to 3,300 vehicles continued to the Minnesota border.

US 14 Alternate
The US 14 Alternate in the Spearfish Canyon.
The US 14 has an alternate route between Spearfish and Sturgis of 67 kilometers in length. This alternate route goes further south through the Black Hills and is a lot longer than the most direct route between the two places, which is only 30 kilometers long. From Spearfish, US 14A heads south through the spectacular Spearfish Canyon to US 85, then heads northeast again along with US 85 along Lead. Both routes split at Deadwood, after which US 14A heads east through Boulder Canyon. US 14A then ends at I-90 at Sturgis.
History
US 14 was created in 1926 and started in Philip at the time. The route has changed quite a few times, extended to Spearfish in 1928, shortened again to Rapid City in 1929, and again to Philip in 1932. The route has been in Wyoming since 1934. In the 1960s, most of I-90 was constructed east of Spearfish, although the portion near the Wyoming border did not open until 1978. With this, US 14 west of Wall was completely replaced by I-90.
Traffic intensities
900 vehicles drive daily at Wall, dropping to 700 vehicles east of Philip and rising to 1,500 vehicles at Pierre. East of Pierre, 3,000 vehicles travel on the double-numbered US 83, then descending to 1,400 vehicles until Huron. At Huron, 2,300 vehicles and 1,500 to 2,200 vehicles continue to Brookings. Brookings is the busiest point with 8,200 vehicles, then drops to 1,400 vehicles on the Minnesota border.
