Improvements to the SH1 and Loop Road intersection to make it safer and easier to use. This is part of the important strategic link between Auckland and Whāngārei.
Construction of the first stage of the SH1 Loop Road Safety Improvements project is now complete.
However, due to a wet winter, there is final road surfacing of the southbound lanes heading into the roundabout required later this year.
Until then, you may see a small crew working away from the road completing fencing, landscaping and other minor finishing works.
We hope work on the second stage, which will see the Loop Road roundabout increase to two lanes, will be ready to begin within the next construction season later this year or early next.
Creating a dual lane roundabout means an additional southbound lane is required on SH1 as well as a new bridge to accommodate the additional lane. The new bridge and lane will ensure southbound traffic exiting the roundabout have a safe distance to merge back into a single lane before Portland Road.
The new bridge will be constructed to the east of the existing bridge, which will be kept for northbound traffic only. The new bridge will be constructed to our current design standards which mean it will be approximately 1.8 metres higher than the existing bridge on SH1.
The higher bridge structure means right turns into, or out of, Oaks Road will not be possible. Northbound and southbound lanes will be separated by a centre wire-rope barrier. We have constructed a safe turning area on Portland Road for Oaks Road and SH1 residents to make right turns.
