A trucking company rooted in Joliet, IL.
Joliet sits at the crossroads of American freight. Interstates 80 and 55 meet here, the region's intermodal yards move containers to and from the whole country, and the Chicago market is right up the road. It's one of the best places in the nation to base a fleet — and it's home for MDX Line Inc.
We're an asset-based carrier headquartered in Joliet, Illinois, hauling flatbed and van freight across all 48 states. Local shippers get a carrier that knows the corridors, the yards, and the traffic — with the equipment and drivers to move freight well beyond the metro.

Why Joliet is a freight hub
Few places move freight like Will County. The intermodal terminals in and around Joliet and Elwood are among the busiest inland ports in North America, and the interchange of I-80 and I-55 puts trucks within a day's drive of a huge share of the U.S. population.
For a shipper in the Joliet–Chicago area, that means a local carrier like MDX Line can pick up quickly and route onto major corridors without fighting across town first.
Local carrier, national accountability
Working with a carrier based in your own market has real advantages: faster pickups, drivers who know the area, and a dispatch team in your time zone. But you don't want to trade national reach for those local benefits.
MDX Line gives you both — a Joliet home base and its responsiveness, plus asset-based capacity to deliver anywhere in the 48 states under one company's accountability.
