I-90 Unbonded Overlay: TH 169 to TH 22

Located in rural southern Minnesota, this interstate rehabilitation project aims to extend pavement life and improve ride quality. PE Services provides construction inspection, materials testing, plant inspection, document control, and environmental compliance management to ensure project success.

The project’s proximity to wetlands, farmland, and the Blue Earth River requires meticulous erosion control and stormwater management. Our environmental oversight team conducts post-storm assessments and enforces compliance with federal and state regulations, safeguarding natural resources while keeping construction moving. Through technical excellence and environmental stewardship, PE Services ensures a smooth, durable highway upgrade while minimizing ecological impacts.
