Case Study

I-69 Reconstruction

Michigan Paving & Materials (MPM) led the full reconstruction of a 24.5-mile stretch of I-69 in partnership with MDOT. The result: a major infrastructure upgrade delivered years ahead of schedule.

Project Overview

Location

Interstate 69 (I-69), Michigan

Timeline

3 years

Project Type

Full Reconstruction

Services Provided

Design and engineering oversight, materials supply, and project management

Client

Michigan Department of Transportation (MDOT)

Project Size

24.5 miles, including multiple interchanges and bridge structures

Project goals

The goal of this initiative was to completely rebuild a deteriorating 50-year-old stretch of I-69, heavily traveled by over 90,000 vehicles daily. Originally slated as a decade-long, four-phase project, MDOT sought a more efficient approach that could reduce disruption while delivering long-term durability.

Our approach

Michigan Paving & Materials (MPM) partnered directly with MDOT to take a proactive role in both the design and engineering phases—running them concurrently with construction to accelerate the timeline. This design-build synergy enabled MPM to compress the work into a single multi-year program rather than spread it out over 10 years.

To support continuous progress, MPM utilized three nearby asphalt plants—each within 30 miles of the job site—and set up a portable concrete crushing plant to recycle removed pavement into reusable aggregate. These steps reduced hauling time, minimized material costs, and improved efficiency.

Results

  • Faster delivery: Completed in just over 3 years—one-third of the original timeline.

  • Sustainable reuse: 425,000 tons of concrete crushed and reused on-site.

  • High-volume production: 750,000+ tons of asphalt produced and paved.

  • Long-lasting surface: Expected lifespan of 25+ years with minimal upkeep.

  • Award-winning: Recognized by NAPA and Roads & Bridges as a top U.S. project.
