New location of Highway 44 bridge not far from current one
In 2016, a South Dakota Department of Transportation (SDDOT) study of major bridges identified the Platte-Winner bridge as a top priority for replacement in the next decade. And because the existing SD44 highway between highways SD47 and SD50 has also experienced numerous landslides since the current bridge opened in 1966, resulting in extensive repair and mitigation expenses, they determined that it is also prudent to evaluate options for maintaining SD44 in the most stable location possible.
The objectives of the bridge replacement project are to provide long-term (100+ years) service, maintain crossing and river navigation during construction, and avoid impacts to buildings, especially at Snake Creek Recreation Area, as much as possible.
The initial findings determined that the existing location is about optimal for length and that the bridge cannot be repaired or replaced in the same location and still meet objectives.
