CUNNINGHAM'S Gap has been opened again, although the trip through is likely to take a little longer than it has of late.

About 5pm yesterday afternoon, the Gap was open to one-lane of traffic, operating under stop-slow conditions.

A Department of Main Roads and Transport spokesman said the patch of highway sustained landslides at several locations.

"The landslips are located towards the top of Cunningham's Gap, in the area where the shipping containers are located.

"While most of the slips impacted only part of the highway, one landslide of mud,

vegetation and topsoil located towards the top of the Gap completely blocked all three lanes."

The damage comes less than two months after the completion of flood reconstruction work, which was completed in December.

Geotechnical investigations were conducted at the site yesterday and a report is to be provided to TMR in the near future.

"The report will provide information around the need for further remediation works where the new slips have occurred," the spokesman said.

"Works will be ongoing to open all lanes of traffic."

According to the spokesman, initial assessment of the damage through the Gap had indicated the reconstruction works have held up well.

"Minor landslips have occurred at new sites that were not part of the 2010-12 reconstruction works," he said.

"We're working hard to keep road users informed of any changes to the road network."

Motorists are strongly encouraged to check 131940, qld.gov.au and phone line before heading out.

These will be updated with the latest information about road closures and incidents.
