South Dakota Highway 25 (SD 25) is a 194.524-mile-long (313.056 km)state highway in the eastern part of the U.S. state ofSouth Dakota. It connectsScotland,Howard,De Smet, andWebster.
It consists of two disconnected segments. Its shorter southern segment extends 19.529 miles (31.429 km) fromSD 50 northwest ofTabor toU.S. Route 18 (US 18) west ofOlivet. Its much-longer northern segment extends 174.995 miles (281.627 km) fromSD 262 northwest ofEmery, through Howard, De Smet, and Webster, to theNorth Dakota state line. Here, the roadway continues asNorth Dakota Highway 18 (ND 18).
SD 25's northern segment was established in 1926, with its southern terminus in Howard. From what is now SD 262, the SD 25 designated was applied to the road as construction occurred. Therefore, the northern terminus was atFarmer by 1971, Epiphany by 1977, and the Howard area by 1981. It was shifted west out of Howard in the early 1950s. Its northern path took azigzag route northward. From De Smet, it went throughClark to Webster. It went west approximately 15 miles (24 km) and headed north toBritton. It then met the North Dakota state line northeast ofKidder. Part of this path is nowSD 27. It was then shifted to its current path. In the mid-1970s, it utilized formerSD 23 from Webster toLake City. BetweenHammer and the state line, it utilized part ofSD 15's former path. The southern segment was the path of formerSD 35. It was redesignated in 1976.
SD 25 begins at anintersection withSD 50 northwest ofTabor, in the southeastern part ofBon Homme County. This intersection is also the northern terminus of County Road 1A (CR 1A; 424th Avenue).

SD 25 was established in 1926, with its southern terminus in Howard. It was then established from what is now SD 262, northwest of Emery, northward. The SD 25 designation was applied northward from this intersection asconstruction of the roadway was completed. The northern terminus of this segment was at Farmer by 1971, Epiphany by 1977, and the Howard area by 1981. Originally, SD 25 went through Howard, but was shifted west approximately 1 mile (1.6 km) in the early 1950s.
On the north end, SD 25 used a zigzag path north from De Smet; in 1927, it went throughClark to Webster, then west about 15 miles (24 km) before heading north toBritton and the North Dakota state line northeast ofKidder. The path north of US 12 is nowSD 27. In the mid-1950s, the highway was shifted eastward to travel straight north from De Smet to US 212 9 miles (14 km) east of Clark. Then, after a 1-mile-long (1.6 km) jog to the east, it traveled north to Webster, and then resumed its previous alignment to North Dakota. In 1976, SD 25 was shifted eastward to use the path of formerSD 23 from Webster to Lake City. It then curved northeast through Veblen and north again atHammer (on the former path ofSD 15).
The southern segment was the path of formerSD 35. This was redesignated as part of SD 25 in 1976.
