The City of Sioux Falls is nearing the completion of a major $39 million infrastructure project at the intersection of Arrowhead Parkway and Veterans Parkway. Expected to be finished by November 20, 2026, the site is slated to become the largest intersection in South Dakota.

The expansion will feature three through lanes and two left-turn lanes in each direction at the cost of $39 million. Additionally, the project includes the installation of three lighted pedestrian underpasses.

The details

Construction crews are currently finalizing the installation of medians, sidewalks, retaining walls, and landscaping at the intersection site. Once fully operational, this expansion will accommodate increased vehicle volumes with its expanded lane capacity.

Key Data

This project mirrors the regional trend of upgrading major arterial roads in line with the South Dakota Department of Transportation's 2024 State Transportation Improvement Program. It follows the pattern of prioritized urban infrastructure funding established by the state's transportation initiatives.

Commuters can anticipate significant improvements in traffic flow and reduced congestion once the three through lanes and dual left-turn lanes open. Residents should also expect improved safety for foot traffic thanks to the inclusion of new lighted pedestrian underpasses.

The takeaway

Large-scale infrastructure projects like the Arrowhead and Veterans Parkway expansion reflect a commitment to managing long-term urban growth in expanding cities. Residents should prepare for final construction phases that may influence local traffic patterns leading up to the November 2026 completion.
