State Highway 16 Stage 2

SH16 Brigham Creek to Waimauku Stage 2 investigations

SH16 Brigham Creek to Waimauku Stage 2 is in the investigation phase for design.

The team will be doing survey work along the highway between Brigham Creek and Kumeu, as well as on Coatesville/Riverhead highway. The works will take place from the week beginning Monday 5 October, weather permitting, and will take approximately 3 weeks to complete. Works will take place outside of peak hours to minimise disruption to the public.

The works will involve surveyors working on foot along the side of the highway. We will be using topographical survey equipment to survey existing ground topography and drainage features.

What this means for you

Work within the state highway corridor requires a Traffic Management Plan. This ensures our workers are safe when undertaking the surveys and we manage any disruption to the public.

We will set up sites from 9am for removal from 4pm. Our works will take place between 9.30am and 3.30pm, Monday to Friday, weather permitting. Our team will be working in the road shoulders so we will not be impacting on traffic lanes or restricting parking.

Surveyor on State Highway 16

Why are you doing this work?

Topographical surveys are used to survey the land and collect vital information which we use to inform our planning and design. Later we will need to undertake geotechnical surveys, which are invasive and require machinery to measure the strength of the land and assess soil and rock at particular locations.

The project will improve both safety and capacity along this busy route whilst long-term investigations are underway to address growth and congestion in the Northwest. Stage 2 is the section between Brigham Creek and Kumeu, which will include:

• Putting in flexible road safety barriers to catch drivers who leave their lane before hitting something harder like trees, poles, ditches or other vehicles. Flexible barriers will be installed along the road except between Taupaki and Kumeu.

• Adding extra lanes between Brigham Creek and Taupaki roundabout from two lanes to four (two in each direction), to help improve travel times in the short-term, ahead of a longer-term improvements.

• Putting in a flush median, which is a painted area in the middle of the road to give you more room and a safe place to wait before turning, while traffic can continue to flow.

• SH16/Coatesville Riverhead Highway intersection improvements to help traffic flow better and make it safer to turn.

• Creating a new shared path between Kumeu and Brigham Creek for walking and cycling. By connecting into the wider Auckland cycling network, we are providing genuine travel choice for the community.
