In a significant infrastructure enhancement for South Dakota, the Interstate 90 construction project near Wasta is set to commence on Monday, March 2, 2026. This pivotal project, focused on reinforcing the transportation backbone of the state, emphasizes both safety and efficiency for South Dakota’s travelers.

The current phase of the project involves the meticulous demolition and reconstruction of the eastbound bridge over Bull Creek. This endeavor includes extensive approach grading and the application of new asphalt surfacing, ensuring a smooth and durable roadway for years to come. This marks the second phase of construction; the initial phase concluded successfully in November 2025, with the replacement of the westbound bridge.

South Dakota’s Commitment to Infrastructure

The importance of this project extends beyond mere transportation; it demonstrates South Dakota’s commitment to maintaining and improving its infrastructure, which is central to its economic and social vitality. The state is characterized by its vast landscapes and dispersed population, which makes reliable roads critical for connecting communities and supporting local businesses.

South Dakotans have historically demonstrated resilience and innovation, often facing challenges head-on. This project is no exception. By investing $15.1 million through Heavy Constructors Inc., stationed in Rapid City, SD, the state underscores its dedication to fostering a robust infrastructure that meets the needs of its residents and visitors alike.

Impacts on Travel and Safety Measures

Motorists navigating through the construction zone will experience a rerouted traffic flow. The configuration will channel vehicles into two-way traffic within the westbound lanes for approximately three miles. To prioritize safety, the speed limit in the project area will be lowered from its usual 80 mph to 65 mph and further reduced to 45 mph during active construction hours when workers are present.

Jason Baker, the project engineer, emphasized the importance of driver awareness during this period. “Motorists should be prepared for suddenly slowing and stopped traffic and be attentive to construction workers and equipment adjacent to the roadway,” Baker noted. His remarks highlight the collaborative effort between the Department of Transportation and the public to ensure smooth and safe travel.

The project anticipates completion by August 5, 2026. This timeline reflects the diligent planning and execution capabilities of the SDDOT and its partners.

For the Community, By the Community

Heavy Constructors Inc., with its local roots in Rapid City, signifies the project’s community-oriented approach. The benefits of engaging a local company extend beyond logistical efficiencies; it speaks to a deeper connection with the community’s needs and aspirations. Notably, this project supports local employment and economic growth, underpinning the South Dakota ethos of community development.

Furthermore, this construction project aligns with the strategic goals of the SDDOT, which aims to provide a safe and efficient public transportation system to enhance the quality of life for South Dakota’s residents. As the state continues to innovate and tackle infrastructure challenges, projects like this serve as milestones of progress.

The Road Ahead

For travelers, the completion of this project promises a safer and more efficient route, increasing the ease of access to the treasures of South Dakota, from the rolling prairies to the majestic Black Hills. The state’s ongoing commitment to infrastructure not only bolsters travel and commerce but also strengthens the community bonds that make South Dakota a unique and welcoming place.

In essence, the Interstate 90 construction project is more than just a bridge replacement; it is a testament to South Dakota’s forward-thinking and community-centered approach. As residents and visitors alike anticipate the improved roadways, the state continues to exemplify innovation and resilience on its paths to a future that respects its rich heritage while embracing new possibilities.
