The Ilkley Road overpass remains closed at Tanawha after a truck carrying an excavator struck the bridge on the Bruce Highway on Friday.
The highway was closed due to the incident but has since reopened and police are investigating how it happened.
However, the southbound lanes of the highway near the overpass have a 60km/h speed restriction while there’s no change northbound.
Queensland Transport and Main Roads (QTMR) said the bridge has been temporarily wrapped to help prevent further debris from falling, ahead of repair works.
Further investigations and work is needed in coming weeks to prepare for permanent bridge repairs.
QTMR said this may require southbound lane closures, which will be scheduled as night works to minimise disruption.
Timeframes will be confirmed once details are available.
