SPEARFISH, SD (July 29, 2022) - The contractor at Sandstone Hills Drive has experienced numerous delays while working on upsizing the sanitary sewer main.
There is large number of utilities in this location that makes working in this area difficult and tedious. The gas line was directly over portions of the sewer main and will need relocated. The watermain was at an elevation that conflicted with the new upsized sewer main. After re-aligning the watermain we experienced a water main break under Colorado Boulevard. The soil conditions in combination with the depth of the sewer main has made excavation challenging and hazardous. The contractor will be changing their excavation methods to make the work safer for their employees. This will result in an increased amount of construction traffic as they haul material off and on the project.
A new watermain will need to be bored under Colorado Boulevard. This will result in Sandstone Hills Drive continuing to be closed. Once we have an estimate on when materials will be delivered and schedules for a subcontractor to bore the casing pipe under Colorado Boulevard, we will have a better estimate of when this work will be completed and re-opened to traffic, but this could result in the closure of Sandstone Hills Drive continuing into the fall.
The contractor will work to accelerate the work on Windmill Drive and plan to start the mill and overlay in the next few weeks. Then progress over to Iron Horse Loop to complete the work on that route.
The intent is that the contractor will still complete all of the work this fall, just not in the order originally planned.
We appreciate your patience while the contractor works through these challenges. Additional notifications will be sent out as the work progresses and we have updated timeframes for when traffic configurations will be changing.

Detour for Sandstone Hills Drive (from Colorado Blvd. to Windmill Dr.) begins Saturday
SPEARFISH, SD (June 16, 2022) - The Contractor plans to begin work on the sanitary sewer upsize on Sandstone Hills Drive on Saturday June 18, 2022, from Colorado Boulevard to Windmill Drive.
Sandstone Hills Drive will be closed from Colorado Boulevard to Windmill Drive for approximately 4 weeks scheduled until the completion of the sanitary sewer upsize and resurfacing. The Detour route will be on Colorado Boulevard, 27th Street, and Windmill Drive.
During this work, the intersection of Sandstone Hills Drive and Windmill Drive will also need to be closed while the Contractor replaces the manhole in the intersection for about one week. The detour for this work will be on Branding Iron Drive, Saddle Horn Drive, Bluestem Boulevard, and Woodland Drive. Additional notifications will be sent out at that time.
The detour routes will be marked with signs.
The contractor plans to continue work on replacing concrete curb, gutter, sidewalk, and asphalt patching in other areas of the project while limiting impacts to the detour route(s).
