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.”
Motorcycle Advocacy Group (MAG) member Stuart Langfield says the speed limit was reduced because the council believed it would reduce the noise of the vehicles to the residents.
“At the AGM of the local residents last year I informed them it would not reduce the noise level but extend its duration by another 50%,” he says.
“Feedback from the residents is that I was correct.”
Motorcycles will also be louder as they will have to engage a lower gear along this section.
