It will remain restricted to single-lane traffic until the end of November for remedial work.
Moreton Bay Regional Council says the speed limit on that section of the road will be reduced 33% to 40km/h permanently.
Division 11 Councillor Darren Grimwade says there were “a number of curved sections of the road which currently had recommended (but not enforced) speed limits of less than 60km/h”.
“The section of Mt Nebo Road which is currently being remediated has a temporary speed limit of 40km/h as a result of the restriction to one lane under traffic control,” he says.
“During the development of the road reconstruction design two years ago, the Mt Nebo Residents Association requested a permanent reduction to 40km/h along these curved sections of the road.
“A recent speed review was carried out by council along the whole length of Mt Nebo Road which confirmed a permanent reduction to 40km/h along these sections was appropriate and will be implemented to improve the safety of motorists at the completion of remediation works.”
