Unsafe South Dakota Bridge Closed

South Dakota officials have closed a Minnehaha County bridge because it is unsafe.

The Highway 114 bridge just west of Baltic spans the Big Sioux River. County Highway Superintendent D.J. Buthe tells the Argus Leader newspaper that a worker spotted structural flaws in support beams during a regular inspection Tuesday.

The bridge was built in 1956. It was scheduled to be replaced in 2014, but Buthe says the project could happen earlier now. It could cost more than $3 million.

About 1,100 people live in Baltic.
