Welcome to our Infrastructure Projects Page!
Please see below for summaries of projects currently ongoing in our community. This list is not all inclusive and summarizing often complex and detailed engineering projects can be challenging. So please, please engage staff with any questions, comments, and concerns. We would love to discuss with you!

Sewer Mains Televising (6/12/19)
The city has contracted with a vendor to televise and obtain condition information of the sewer mains in the southeast area of Harrisburg. This is expected to occur in the next month. City crews will be cleaning the mains in preparation for the televising. Please take special care when driving near the city and vendor vehicles in the roadway.
Televising a portion of the town's sanitary and storm sewer is an annual program and helps us to plan the replacement and rehabilitation schedule.
Lion's Park Entrance Sinkhole (N Perry Ave & Marie Dr) (6/12/19)
A small sinkhole has formed near the entrance to Lion's Park due to storm sewer pipe separation. Please avoid the area marked by cones or barricades. The city is hiring a contractor to repair this within the next week.
East Side Drainage Study and Improvement Analysis (6/12/19)
We are beginning to study the drainage basin north of Willow St and east of the railroad which includes the Legendary Estates stormwater outlet and N Southeastern Ave. The study is expected to take about 6 months. Once this is complete, we can then determine the appropriate road profile for N Southeastern Ave. Also after this study is complete, we can then determine drainage solutions for the the southeast area of town including the Willow St ditch, Perry Ave, and Anna Way.
Willow St Railroad Crossing (6/12/19)
The railroad crossing is planned to be improved for smoother vehicle crossing in the next couple of months. Next year the crossing arms are planned to be updated and sidewalk replaced and installed on the south side.
Low Impact Design Pilot Project (6/12/19)
We are conducting a test project for low impact design of streets and storm water. The project is planned to be installed along Willow St this year or next year. It is currently being designed.
Central Park (6/12/19)
The grading and storm sewer installation of phase two of central park (north of Liberty Elementary) has been rescheduled to occur in 2020. The long term schedule to complete all the proposed park amenities is still undetermined due to many variables, including budget.
Southeastern Ave from Willow St North to Legendary (6/3/19)
Millings were applied to segments of the road that are in poor condition as a temporary fix. Later this summer, this portion of the road will undergo subgrade reclamation/regrade/compact and then apply a new asphalt mat. This is not expected to occur until mid to late June. Vehicle weight limits remain in effect.
Streets Slurry Seal (6/3/19)
Several residential streets will have this slurry seal applied to them in early August. This asphalt surface coating will protect our roads in an effort to increase their useful life. Specific streets and traffic control information will be provided soon.
Concrete Repairs (6/3/19)
Spot repairs on curb and gutter, valley gutters, and sidewalks is occurring throughout Harrisburg. This is an annual program.
Arterial Street Funding Study (6/3/19)
An arterial street funding study for our city is underway. This is vital step in the complex process of determining how to pay for our arterial streets.
Sidewalks & Trails (5/28/19)
A sidewalk along the north side of Willow St from Liberty Elementary to the High School will likely be constructed in the summer of 2020.
Staff is taking inventory of streets without sidewalks and locations of sidewalks in need of repairs and ADA improvements. After compiling this data, we will be working with our city boards and community organizations to prioritize the improvements. Then, a long term plan will be developed. Funding these improvements will likely dictate the schedule of installation.
Cliff Ave and Willow St Intersection (5/28/19)
This intersection is owned jointly by the Harrisburg and Lincoln County. Harrisburg recently conducted a traffic study of the high traffic intersections in Harrisburg, including this one. Lincoln County is currently conducting a Transportation Master Plan. Once the study is completed later this summer, we use this data to determine the best path forward for this intersection.
Wastewater Treatment Facility & Existing Lagoons (Last Updated 4/26/19)
We are in the process of building our own wastewater treatment facility. During the past few months we’ve been selecting our team of consultants to assist us in this endeavor. The project is currently at 30% design phase and we are scheduled to break ground in the fall of 2019 with construction occurring until spring of 2021. Facility start up will occur during the summer of 2021. In the fall of 2021 our wastewater ponds 1 and 2 will be decommissioned and pond 3 will then only be used during high flows and emergencies. Meetings with our construction management team are ongoing.
Projects of Interest by Others
Lincoln County Master Transportation Plan (Lincoln County & SDDOT) (6/3/19)
Lincoln County and SDDOT are currently studying the county road system to prioritize improvements in response to the rapid growth. This report is expected to be completed late this summer. The information from this study will assist Harrisburg immensely in our future transportation planning.
Highway 115 Reconstruction (SDDOT) (6/5/19)
**The intersection of Minnesota Ave and Willow St will be closed starting Monday, June 10 and will remain closed for 1 week.**
This is a 2 year project. In 2019, Highway 115 (Minnesota Ave) from just south of the intersection of Highways 115 and 110 (Minnesota Ave and Willow St) north to Cardinal Pl (just south of 271st St) will be completely reconstructed. In 2020, reconstruction will occur from Cardinal Pl to 85th St.
The southern portion of the 2019 project, from just south of the intersection of Minnesota Ave and Willow St to the apple orchard will be closed from about April to about September. The remainder, from the orchard to Cardinal Pl will be closed from about September to about November. The intersection of Minnesota Ave and Willow St will be closed this summer for 40 days. This will likely not occur all at one time. The exact closure dates are not yet known.
As soon as we have any additional information, we will disperse it to you via our city website and/or our Facebook page. For the most up-to-date and accurate information, please contact the DOT directly. The road closures will be an unavoidable inconvenience for a while. Please allow yourself extra time for travel in consideration of this.
