This included land slips, shoulder and embankment erosion, the erosion of drains and damaged rock fall netting. The road wasn't fully repaired with all four lanes open until September 2011. The Toowoomba Bypass was completed in September 2019 and bypasses the urban area of Toowoomba and provides a better crossing of the Great Dividing Range.

The bypass continues as the Gore Highway (A39) and is 41 km in length. The original section of Warrego Highway through Toowoomba was renamed Toowoomba Connection Road (A21).
