New Arterial Road - West Kaiapoi

A new arterial road is to be constructed in west Kaiapoi to cater for ongoing development of land around the western side of Kaiapoi and will provide a key link to West Rangiora and Southbrook.

About the Project

A new arterial road is to be constructed in west Kaiapoi to cater for ongoing development of land around the western side of Kaiapoi and will provide a key link to West Rangiora and Southbrook. The project is underway and a completion date is set for late February 2018. The completion date is dependent upon the two bridges being completed on time.

The road will extend from the Ohoka Road off-ramp and will curve around onto Butchers Road before joining back onto Island Road near Mill Road. The purpose of the road is to direct the through traffic away from the new residential area of Silverstream. The road will address safety issues at the intersection at Ohoka Road/Island Road and Cosgrove Road. Improvements will be made at intersections along the new arterial road. The new road will be two lane (one in each direction) and will involve the construction of two new bridges along the alignment.

In the future Island Road between Mill Road and Adderley Terrace will be closed to through traffic and the New Arterial Road will form the main link through to Kaiapoi. While Adderley Terrace will still provide an alternate route through to Kaiapoi, traffic will only be able to use this approaching from the south east, as Island Road will be closed between Adderley Terrace and Mill Road later this year. Once that happens, access to Adderley Terrace from the north will no longer be available. Refer to the map to view the future road layout.

A tender has been awarded to HEB Construction Ltd for the physical works. Work began on site in January 2017. Hours of work are 7.30 am to 6 pm, Monday to Saturday. Some night work will be undertaken to help reduce the impact on road users. Residents will be notified in advance of night work being undertaken.

Traffic Impacts

  • Access to properties will be maintained during the work
  • If any access restrictions are required we will notify you in advance
  • Temporary traffic management will be in place during the work
  • Some aspects of the work may be undertaken as night work to reduce the impact to traffic. Advance notification will be provided.

Project Update - Upcoming Road Closures and New Traffic Layout

Work on the West Kaiapoi new arterial road has been going well with the two new bridges constructed and the road nearly complete with the exception of the Mill Road intersection tie in with the new road and guardrail installations.

The next phase of work will require the traffic to be moved onto the new arterial road so that filling work can continue at the Mill Road intersection.

On Monday 15 January traffic will be moved onto the new arterial road at 10.30am. A significant change that motorists need to be aware of is that traffic travelling on Ohoka Road across Island Road will have right of way, with Island Road traffic being required to stop and give way to Ohoka Road traffic.

To allow this work to be carried out in a safe manner and as quickly as possible, it is also proposed to close Mill Road between Island Road and Christmas Road. At the same time Island Road will be closed to through traffic, east of Mill Road (refer to map).

The following road closures will be in place as follows:

  • Mill Road between Island Road and Christmas Road will be closed starting Monday 15 January 2018 from 10am for a period of two weeks and reopening on Wednesday 31 January at 6.00pm.
  • Island Road between Adderley Terrace and Mill Road will be closed to through traffic starting Monday 15 January 2018 from 11am. This road will not reopen to through traffic.

Traffic Impacts:

  • Ohoka Road and the new arterial road traffic will have right of way, with Island Road traffic being required to stop and give way to Ohoka Road traffic
  • Mill Road traffic will be detoured via Christmas Road & Butchers Road through to the New Arterial Road from 15 to 31 January  2018
  • Adderley Terrace traffic heading to Ohoka and Rangiora will access the new arterial road via Silverstream Boulevard and Hayson Drive
  • Detour routes will be signed, please follow the on-site signage
  • Access to properties will be maintained at all times
  • Access to emergency services will be maintained at all times
  • The new arterial road will be operating with a speed restriction in place

Please take care when travelling through the site
