Heavy traffic expected after on-ramp closure
Motorists may face delays this weekend while the Great North Road westbound on-ramp to Auckland's Northwestern Motorway (SH16) is closed for roadworks.
The NZ Transport Agency said motorists should use alternate routes to keep traffic volumes in the Great North Road interchange area to a minimum.
The ramp will be closed from 9pm tonight until 5am on Monday.
The agency said the closure was to allow work to improve the on-ramp as part of its causeway upgrade project.
"We are expecting that traffic in the Great North Road area will be heaviest on Saturday and Sunday afternoons between midday and 4pm so making alternate plans for travel, particularly at those times would be appreciated," said the agency's Highway Manager, Tommy Parker.
Bus services would use the St Lukes and Patiki Road on-ramps as alternatives to Great North Road. The northwestern cycleway would remain open throughout the vehicle on-ramp closure.
City or eastbound drivers using the Great North Interchange or the Northwestern Motorway would not be affected by the closure.
Meanwhile the agency said traffic disruptions were also likely from Sunday as State Highway 1 on the Brynderwyn Hills in Northland was closed overnight for maintenance work.
Weather permitting, the highway over the Brynderwyns will be closed in both directions from 6.45pm, and will re-open the next morning at 5am. The first stage of work will continue for five consecutive nights from Sunday, and the highway will be closed a second time on Sunday 6, 7, and 8 April.
Southbound traffic will be diverted through Waipu and Mangawhai, and northbound traffic will be diverted via Paparoa/Oakleigh.
The agency said people travelling between Auckland and Northland should allow an extra 30 to 45 minutes for their journey.
