Eastbound motorists are being warned to change their ways or prepare to suffer.
Auckland Transport says work due to start at the Panmure roundabout next week could make getting through the area more difficult for Pakuranga, Howick and Botany residents.
Major traffic changes will be in place from October 28 so work can begin on replacing the Ellerslie-Panmure Highway bridge. Some delays are likely for about a fortnight until drivers get used to the changes.
Eastbound traffic will be reduced to one lane on the approach to the roundabout and northbound traffic for Glen Innes will be diverted to a route around it.
There will be no changes for westbound traffic with two lanes remaining open on Ellerslie-Panmure Highway.
The traffic diversion will allow preparations for demolishing the Ellerslie-Panmure Highway bridge on the approach to the roundabout later this year. At the end of November traffic will be shifted on to a bridge next to the existing one that is in the final stages of construction.
A new higher and longer Ellerslie-Panmure Highway bridge will then be built during the first eight to nine months of 2013.
Auckland Transport major projects manager Rick Walden says drivers should expect delays at peak times as people get used to the changes.
"We encourage people to check the signs when they're travelling through the area and get into the correct lane early," he says.
Drivers heading east to Panmure town centre or Pakuranga should use the right lane on the Ellerslie-Panmure Highway and continue through the roundabout.
Traffic will be reduced to one lane between Forge Way and Panmure roundabout.
Traffic heading south or west from Glen Innes/Jellicoe Rd, Panmure, Pakuranga and Howick will continue to come through the roundabout and on to Ellerslie-Panmure Highway.
Transpower is also working on Waipuna Rd and Pakuranga Highway as part of its North Auckland upgrade.
Delays are being experienced on Waipuna, Ireland and Carbine roads and Ti Rakau Dr as a result of this work.
