St. Louis heavy haul

Superloads in Missouri

Reliable Transport LLC runs heavy haul and superload moves across the USA and Canada from Dayton, Ohio. In January 2025 we moved a 220,000 lb submarine engine within Missouri. For a St. Louis load, our in house team files the MoDOT permit, times the move around the metro curfews, plans any bridge crawl and books the escorts.
