A spokesman for Transport Minister Rachel Nolan last month said the Mt Lindesay/Beaudesert Strategic Transport Network Investigation would be available for public consultation by mid-April.
Last week, the spokesman said Ms Nolan was yet to be briefed on the study and he could not give a revised date for when it would be released.
He said the Minister would be briefed by the end of the week and expected the study would be released “a short time after that”.
