Project Update 2021-06-04

RAPID CITY, S.D. – June 2, 2021 – A maintenance crew will be onsite during precipitation events and through the weekends to continue to maintain the road.

Roadway excavation and culvert installation continue from Highway 385 to the westernmost Spring Creek bridge.

Roadway excavation and undercutting continue near Victoria Lake Road, moving west to Old Sheridan Road. Preparation continues for the first lift of gravel and millings placement through Old Sheridan Road. The reclaim and milling operation began this week from Old Sheridan Road going west to Rockwood Road. Storm sewer installation continues moving west from Victoria Lake Road to Stirrup Court.

Traffic to The Marina at Sheridan Lake must use the gravel detour from Highway 385. The Marina is not accessible from Sheridan Lake Road during this construction season.

The speed limit is 35 mph from Norseman Lane to Rockwood Road. Sheridan Lake Road is fully closed from Spring Creek Trailhead Road to Highway 385. Thru traffic from Rapid City to Highway 385 must use an alternate route. Motorists are asked to be aware of suddenly slowing and merging traffic, changing work zone locations, reduced speeds through the work zone, and construction workers and equipment adjacent to the driving lanes.

Additional information will be provided as phasing, access, and traffic control changes with the progression of the project. To view the entire scope of the project, with the phasing and traffic control plans as well as weekly updates, please visit the project website or the ArcGIS StoryMap located at: Interested persons can also follow the project on Facebook, “Sheridan Lake Road Reconstruction,” and on Twitter, “Sheridan Lake Road Reconstruction@FerbEng.” The public may leave a message at (605)343-3311 with any questions or concerns regarding this reconstruction project.

  1. There were County guys out looking at the drain in Countryside neighborhood. I showed them that the rocks in the mouth of the drain have silted in. They didn’t sound concerned, but I’m worried that it will wash out into the grass around the rocks. Should this silt be vacuumed out?
