A RMS spokesperson said, after a recent speed zone review, the existing 70km/h speed on the route along Thomas Street, Newcastle Road and Griffiths Road will be reduced to 60km/h, from 460 metres west of Lake Road at Wallsend to 100 metres west of Beaumont Street at Hamilton.

The changes will be introduced on Sunday.

“The safety of motorists and pedestrians is important to the NSW government which is why steps are being taken to improve safety along this very busy stretch of road,” the spokesperson said.

“In the five years between July 2011 and June 2016 there were 382 crashes, including 272 injury crashes along this 8.5 kilometre section road.

“The injury crash rate per kilometre is almost five times higher than the typical rate for an urban arterial road with a 70km/h speed limit which is why action is needed.

“The reduced speed limit will provide significant road safety benefits to the 40,000 motorists who travel along the route each day.

“In addition to this, the changes will also improve safety near Hamilton North Public School for students and their families, including the Newcastle Showground which becomes very busy when events are on.

“Electronic message signs will be in place to advise motorists of the changes and will remain for at least a week after the new speed limit signs have been installed.

“Motorists are reminded to observe the new speed limit and are advised to drive to conditions.”
