Case Study: CSAH 5 & CSAH 25 Concrete Pavement Project
Multi-Mile County Road Reconstruction — Olmsted County, Minnesota
As the paving contractor, Doyle Conner Co. played a central role in reconstructing key segments of County State Aid Highways serving rural communities in Olmsted County.
This large infrastructure project involved constructing approximately 4.25 miles of new concrete pavement along CSAH 5 and CSAH 25, connecting the communities of Byron and Salem Corners.
Project Overview
The project focused on replacing aging roadway infrastructure with a durable, long-lasting concrete pavement system designed to support heavy rural traffic and provide decades of reliable service.
Key elements of the work included:
- Installation of approximately 4.25 miles of concrete roadway
- Placement of 8-inch-thick high-performance pavement
- Coordination with grading and site preparation crews
- Maintaining roadway access throughout construction
Concrete was selected for its superior durability, strength, and resistance to Minnesota’s freeze-thaw cycles — making it an ideal solution for long-term county road performance.
Maintaining Access for Residents
A unique and critical aspect of this project involved working closely with property owners along the corridor. Because the route served rural homes, farms, and businesses, maintaining driveway access throughout construction was essential.
Doyle Conner Co. coordinated carefully to:
- Sequence paving work around active driveways
- Provide temporary access solutions when needed
- Communicate regularly with residents
- Minimize disruptions during each construction phase
This collaborative approach helped ensure smooth project progress while maintaining strong community relations.
Specialized Equipment Utilized
To achieve the required precision and efficiency across miles of roadway, Doyle Conner Co. utilized advanced paving equipment, including:
Trimmer Machine
Prepared the subgrade with accurate elevation control to create a uniform foundation for the new pavement.
2800 Slip-Form Concrete Paver
Enabled continuous, high-production placement of concrete with consistent thickness and alignment across long roadway segments.
Cure & Texture Machine
Applied curing compounds and surface texturing to enhance pavement durability, skid resistance, and long-term performance.
This equipment allowed crews to maintain strict quality standards while keeping production on schedule.
Quality Standards & Phased Construction
As with all major roadway projects, the work required strict adherence to engineering specifications and carefully planned phasing.
Doyle Conner Co. maintained a strong focus on:
- Precise pavement thickness and grade control
- Compliance with county and state specifications
- Proper jointing and finishing techniques
- Meeting milestone deadlines within each construction phase
Attention to detail throughout the process ensured the finished roadway would perform reliably for decades.
Delivering Durable County Infrastructure
The completed CSAH 5 and CSAH 25 roadway improvements now provide a smoother, safer, and more durable transportation route for residents, agricultural operations, and commercial traffic throughout the area.
Proven Experience in Long-Range Concrete Paving
This project demonstrates Doyle Conner Co.’s ability to successfully manage multi-mile paving operations while maintaining community access, meeting strict specifications, and delivering high-quality results on schedule.
With decades of experience across Minnesota, the company continues to be a trusted partner for demanding roadway and infrastructure projects.
