MOTORISTS driving westbound on the Ipswich Motorway through Goodna yesterday faced traffic delays with an unusual cause – a hump that appears and disappears.
Ipswich police were first called out to the motorway after the hump was reported about 7.30am.
The initial call to police suggested that it was a "big large bump" that was "one metre wide and 20cm high", but other reports suggest it could have been bigger.
Traffic was affected on the motorway near the Goodna train station as motorists avoided the hump, but police and Origin Alliance motorway construction crews had trouble finding it.
The State Government's traffic website – www.131940.qld.gov.au – described it as a "large lump in the road on the Ipswich Motorway in the right lane near the Goodna railway station".
It then reportedly disappeared, but again at 9.30am police were called out to the same site after drivers reported seeing the mystery hump. Again it disappeared shortly afterwards.
A spokesman for the Department of Transport and Main Roads said crews would continue to address "any cracking in the pavement, which occurred as a result of the bump, at the earliest opportunity".
"As soon as the bump was noticed, messages were placed on the VMS boards and traffic reporters were notified," a statement said.
The hump has not been the only traffic impediment on the Ipswich Motorway near Goodna, with a number of feral deer causing delays last month.
Police said a "large deer" was spotted on the motorway on September 15 by a motorist.
