Weigh-in-Motion system coming soon along Interstate 90

The Minnesota Department of Transportation is installing a new Weigh‑in‑Motion system near Worthington in 2026 to improve freight efficiency.

Sensors embedded in the pavement measure axle loads, vehicle configurations, and speed as trucks travel at highway speeds. This data supports pavement and bridge design, planning, and statewide monitoring of freight trends.

The system also helps law enforcement identify vehicles that may require inspection. Trucks flagged for potential issues can be directed to nearby pull‑off areas for certified weigh‑in and inspection. By screening vehicles in motion, the system improves enforcement efficiency, reduces delays for compliant carriers, and provides a cost‑effective way to support roadway safety in areas without a full weigh station.

Approximately 3.6 miles of Interstate 90 between Diagonal Road and Minnesota 60 near Worthington will undergo pavement and bridge improvements in 2027-28. Additional work includes improvements to lighting, drainage, and guardrail. The timing will coincide with the nearby U.S. 59 Worthington project in 2027-28.
