The Department of Transport and Main Roads had engaged Seymour Whyte Constructions to deliver the high profile Toowoomba Range Remediation Project, which involves batter remediation works on a section of the Warrego Highway through the Toowoomba Range, between Withcott and Toowoomba.

Over 450,000 cubic meters of material was moved around site for use in the realignment of a 1.2km section of the eastbound (downhill) lanes to be vertically flatter and less horizontally curved and an upgrade of 600 m of the westbound (uphill) section.

Soiltech provided a wide range of construction materials testing to Seymour Whyte Constructions to meet TMR specifications and project requirements which was delivered successfully.
