Challenge
East 10th Street is one of Sioux Falls’ most heavily traveled corridors, connecting residential neighborhoods, commercial areas, and the I-229 interchange. Over time, traffic congestion, outdated infrastructure, and aging pavement began to affect safety, efficiency, and accessibility. The corridor also faced drainage challenges, limited pedestrian accommodations, and utility conflicts. The City of Sioux Falls needed a comprehensive improvement project that would modernize the roadway, minimize disruption, and support long-term mobility.
Solution
The City selected HR Green to provide design and construction administration services for the East 10th Street improvements. The project design scope included:
- Adding a third through lane from the I-229 northbound off-ramp to Thompson Avenue
- Milling and overlaying pavement between I-229 and 12th Street
- Converting Blaine Avenue to a cul-de-sac
- Reconstructing accessible curb ramps to meet ADA standards
- Upgrading traffic signals and street lighting
- Installing new storm sewer, water main, and sanitary sewer improvements
- Completing seeding, landscaping, and other site restoration
Construction Administration
During the construction of the Sioux Falls East 10th Street Improvements project, our team facilitated weekly progress meetings and communicated with surrounding property owners to keep the community informed. The team coordinated closely with the City and contractors, reviewed shop drawings and RFIs, monitored construction quality, and ensured compliance with safety, traffic control, and environmental requirements. Construction took place over a 20-week schedule with full-time on-site observation to maintain quality and minimize impacts on businesses and residents.
Benefit
The completed East 10th Street project provides safer, smoother, and more efficient travel along one of Sioux Falls’ busiest corridors. The added through lane reduces congestion near the I-229 interchange, while improved traffic signals and accessible curb ramps enhance safety and mobility for all users, including pedestrians and cyclists. Upgraded storm sewer systems provide greater reliability during heavy rain events, and the cul-de-sac on Blaine Avenue improves neighborhood safety.
