This project consisted of water main replacement on St. Paul Avenue from Benson Road to 39th Street North in Sioux Falls, South Dakota. Work included water main replacement, sanitary manhole repair, replacement of surfacing over trenches, and boulevard restoration. The water main replacement successfully utilized both open trenching and directional drilling methods. Sanitary manhole repair included reconstructing manhole benches and inverts along with installing manhole external frame seals.
This project consisted of installing 8” water main beginning approximately 1,700 feet southwest of the Great Bear entrance road and continuing 3,700 feet to the northeast. This project included water main installation, asphalt removal and replacement, and site restoration and grading. Also included in this project was the grading and paving for a turn lane approximately 600 feet long on Rice Street for the proposed TJN site.
This project consisted of 4,200 L.F. of street improvements on 15th Street (Clark Avenue to Garfield Avenue), Garfield Avenue (15th Street to 12th Street), and State Avenue (Thresher Drive to 12th Street). Also included in this project were 4,400 feet of water main, 2,000 feet of sanitary sewer, and two directionally drilled river crossings approximately 350 feet each. Street paving on 15th Street and Garfield Avenue was with 9″ concrete, with asphalt concrete paving used on State Avenue and at intersecting street tie-ins. ADA accessible sidewalks were also installed on this project for safe access to the middle school and high school.
This project consisted of street improvements on 4th Street from Clark Avenue to Garfield Avenue, which is the downtown business district in Dell Rapids. Also included in this project were improvements to the water main, sanitary sewer and storm sewer in conjunction with street improvements. Street paving on 4th Street was with 8″ and 9″ concrete, with some asphalt concrete paving used on intersecting street tie-ins. All sidewalks were also reconstructed with the use of colored concrete inlays and the existing street lighting was replaced with decorative street lights.
Sanford Hospitals of Sioux Falls, SD built a new Luverne hospital, which required the completion of several smaller projects.
A sanitary sewer study was performed to review the capacity of the sanitary sewer interceptor that served the north end of Luverne. It was determined the interceptor sewers needed to be upsized to 18” and 15” sewer mains. This required removing and replacing 15 blocks of sanitary sewer main, curb and gutter and asphalt paving. New service lines were installed for homes along the project.
Increased traffic and turning movements off/on to US Highway 75 at the intersection of 131st Street was expected at the north end of Luverne. The Minnesota Department of Transportation required lowering the elevation of the intersection approximately 4’ to improve the site distance. Highway 75 was widened to add turn lanes for the increase hospital traffic. The Rock County Highway Department retained DGR to provide the design, plan preparation and construction staking for the project.
