The South Dakota Department of Transportation (SDDOT), in collaboration with the City of Sioux Falls and the Federal Highway Administration (FHWA), invites the public to participate in a crucial discussion about the future of Sioux Falls’ viaducts. A public meeting open house regarding the 10th and 11th Streets Viaduct Replacement Study will be held on Wednesday, May 14, 2025, from 5 p.m. to 6:30 p.m. at the Holiday Inn City Centre, located at 100 E. 8th St. in Sioux Falls. This initiative stands as a vital opportunity for the residents of South Dakota to have their voices heard regarding local infrastructure improvements.
Situated in the heart of the Great Plains, South Dakota boasts a diverse landscape and a rich cultural heritage. Known for its agriculture and serene prairies, the state is committed to maintaining a safe and efficient transportation network. The SDDOT’s mission is a testament to this commitment, as they strive to enhance mobility and promote economic growth through strategic infrastructure projects. This particular study represents a significant endeavor to replace old and potentially unsafe viaduct structures, ensuring continued safety and efficiency for South Dakota’s largest city.
Katrina Burckhard, Planning Engineer at SDDOT and the spokesperson for this project, emphasizes the importance of public feedback. “The goal of this public meeting open house is to gather input on preliminary viaduct replacement design concepts and potential bridge elements,” said Burckhard. “This input will help our study team refine and evaluate alternatives and develop preliminary recommendations.”
The participation of the local community in such projects is essential in capturing diverse perspectives on design elements that can affect daily commutes and city aesthetics. As the urban center of South Dakota, Sioux Falls plays a pivotal role in the state’s economy and serves as a hub for its residents. The replacement of the 10th and 11th Street viaducts is not just about infrastructure; it’s about the future connectivity and vitality of the region.
