NORTH SIOUX CITY, S.D. (AP) — People who live where Iowa, Nebraska and South Dakota meet are waiting for the Big Sioux (SOO) River to crest and hoping the levees hold.
Days of thunderstorms upstream have swollen the river that's now expected to crest between 8-10 p.m. Friday more than a foot above the previous record level set in 1969.
Homes are threatened in all three states, including up to 400 in the McCook Lake neighborhood of North Sioux City, South Dakota.
Crews built a temporary levee across Interstate 29, which should protect much of the city but closed off the interstate and forced motorists onto detours.
Floodwaters already block most roads connecting Sioux City, Iowa, and Sioux Falls, South Dakota.
