SIOUX CITY, Iowa (AP) – An interchange on Interstate 29 in Sioux City has reopened, nearly three months after it was closed because of flooding on the Missouri River. The Iowa Department of Transportation says in a news release Thursday that the I-29 and Hamilton Blvd. interchange has fully reopened to traffic. Transportation officials say the roadway has been cleaned and repainted, and all traffic control devices restored. The ramps on the south side of the interchange had been closed since June 4.
