Street & Utility Improvements
Sioux City Project updates
City of Sioux City, IA
- Planning and coordination with local businesses to maintain access during construction
- Improving drainage along the corridor by adding storm sewer
- Major intersection reconstruction completed half at a time
- New utilities (sanitary sewer and water main) including adding storm sewer where none previously existed along with decorative street lighting and colored concrete sidewalks
- Several stages of construction allowing business access at all times during construction
- Involved a major intersection of two arterial streets with Morningside Avenue and S. Lakeport Street
Morningside Avenue is a main arterial street though the Morningside neighborhood of Sioux City, IA. The original infrastructure dated back to the early 1900’s, with streetcar tracks actually buried under the paving. This project also included the intersection of S. Lakeport Street, a north-south arterial street that extends to Gordon Drive.
Morningside Avenue was reconstructed from just east of S. Nicollet Street to east of S. Lakeport Street totaling approximately 1,300 linear feet. The project included new sanitary sewer, water main (replacing two existing mains), storm sewer, fiber conduits, decorative street lighting, and 9-inch concrete paving with colored concrete sidewalks.
To provide customer and truck delivery access to adjacent businesses, the project was completed in seven stages (including removing/replacing temporary crossovers on S. Lakeport Street through a raised median).
Stage 1a was installing new storm sewer along a portion of S. Clinton from Morningside Avenue to south of intersection of Garretson Avenue and S. Clinton. This provided a storm sewer outlet for Morningside Avenue where none previously existed.
Stage 1b was the reconstruction of Morningside Avenue from just east of S. Nicollet Street east to S. Henry Street.
Stage 2 was extending the reconstruction of Morningside Avenue from S. Henry Street to just short of the S. Lakeport Street intersection.
The final four stages included reconstruction of the intersection of Morningside Avenue and S. Lakeport Street in order to replace utilities and install a new traffic signal. DGR Engineering (DGR) coordinated with the City and contractor to maintain one lane of northbound and southbound traffic on S. Lakeport Street at all times throughout the entire project.
Stage 1a and 1b were completed in 2018. Stages 2, 3a, 3b and 4a and 4b were completed in 2019.
DGR services included gathering survey and utility data needed to prepare detailed plans and specifications as well as construction administration and observation using Federal Aid Funding for the reconstruction of Morningside Avenue.
