How long will the I-75 work last in Saginaw County and south of Monroe?

MDOT expects lane and shoulder closures, plus segments of two-way traffic on the southbound side, to continue through at least mid-November 2026. Construction intensity will vary by phase and season. Drivers should plan for recurring slowdowns during weekday peaks and after incidents. Check MDOT advisories and wnem closings for stage changes and new detours.

What immediate steps can carriers take to limit delays and extra costs?

Shift pickups to earlier windows, pre-clear routes, and confirm appointments with tighter ETA ranges. Stage an alternate plan using I-69, I-475, or US-23 when mileage and service allow. Add buffer to schedules, update detention terms, and keep backup capacity ready on the most affected lanes. Review wnem closings daily for current lane shifts.

Which shipments are most likely to face penalties or chargebacks?

Time-sensitive freight like auto parts, chemicals, and perishables that rely on just-in-time schedules are most exposed. Tight receiver windows increase detention and reschedule risk when queues form near crossovers. If customer SLAs have strict OTIF rules, consider temporary service exemptions, added lead time, or safety stock to reduce chargebacks during active closures.

Will rail or intermodal fully offset the I-75 disruption?

Probably not. Some regional intermodal can help where ramps and schedules align, but service may not match door-to-door speed on short-haul lanes. Expect selective shifts for stable, non-urgent freight. Most time-critical loads will stay on trucks, so the focus should be on routing, buffers, and clearer communication while MDOT bridge improvements continue.
