 | | SOUTH DAKOTA, one of the West North Central states of the U.S., bounded on the N by North Dakota, on the E by Minnesota and Iowa, on the S by Nebraska, and on the W by Wyoming and Montana. |
 | | The E half of the state is relatively humid, but semiarid conditions dominate in the W. Annual precipitation averages 635 mm (25 in) in the SE and decreases to 368 mm (14.5 in) in the NW. |
 | | The state is served by about 120,210 km (about 74,695 mi) of federal, state, and local roads, including 1093 km (679 mi) of interstate highways that cross the state from E to W and (in the E section) from N to S. As in many states, railroad service has declined since the 1940s. |
