We are upgrading wastewater infrastructure in Ilam with the installation of new, larger pipes that will help meet increasing demand from our growing city. 

The project is being carried out in three stages and will be disruptive, with one-way traffic measures in place to allow the work to happen. Read more on Newsline(external link).

Stage one: Clyde and Creyke roads 

The first stage of work runs from September 2024 to December 2025 and includes work on Clyde and Creyke roads.

Traffic impacts

Temporary one-way systems are in place, as follows:

  • Clyde Road (between Riccarton Road and Creyke Road) for northbound traffic. No access for southbound traffic.
  • Creyke Road (between Clyde Road and Ilam Road) for westbound traffic. No access for eastbound traffic.

Detours are in place for affected traffic along Ilam and Riccarton roads. The speed limit is reduced to 30km/h so we can keep our workers, and everyone in the area, safe.

No-entry/exit is in place at:

  • Arts Road, where it intersects Clyde Road.

Residential access to Arts Road is via Forestry Road, off Creyke Road; access to the university is available via University Drive.

Current work focus

Clyde/Creyke corner:

  • Currently, we are working to get around the corner of Clyde Road and Creyke Road. This work involves a number of structures and complexities, but work is going well.
  • We are also finishing the syphon under Okeover Stream (Clyde Road).
  • You may have seen additional traffic management and fenced off areas at the Clyde/Creyke intersection, which is in place to ensure our workers and traffic are managed safely. Unfortunately, this is causing some traffic congestion during peak hours. Please prepare for delays if you are travelling through the area at peak times. Thank you for your patience.

Clyde Road

With underground work wrapping up soon on Clyde Road, we will lay new chipseal in late March or early April. Following this, the road will open to two-way traffic, and access to Arts Road (into the University) will also be reinstated.

Creyke Road

The works at the west end of Creyke Road is also ongoing.

The work scope for stage one includes:

  • Pumping water from below the ground to allow for trenching and excavation works.
  • Trenching and excavation works.
  • Installation of new, larger pipes.

Stage one works began in early September 2024 and will wrap up in December 2025. Stage two will overlap these works when it begins in approximately August 2025.

Further stages will follow stage one, with some overlap in the timing of the stages.

The second stage of the upgrade will affect the east end of Maidstone Road, with work also planned on Creyke Road beside the Clyde Road intersection. This is scheduled to start in August 2025. 

The third stage will happen in early 2026 on Maidstone Road, at the western end between Ilam and Waimairi roads.
