Work will begin from Monday 29 January, and is expected to be completed in late April 2024.

Features of the safety improvements:

• New traffic signals at the Tram Road off-ramp will improve the safety, efficiency, and capacity of the right turn towards Kaiapoi
• Extending the free left-turn will provide a safe merging space for drivers on Tram Road
• Relocation of light poles
• New kerb and channel
• Installation of a two-metre-wide cycle lane around the free left-turn on Tram Road to make it safer for people on bikes travelling west towards Ohoka.

Traffic changes:

• The Tram Road off-ramp will be fully closed at times during the work, primarily overnight between 8pm and 4am. It will be open during weekday peak evening periods
• During off-ramp closures motorway traffic will be detoured via Ohoka Road and Island Road. Please follow signage
• The Tram Road overpass will operate one-way Eastbound only across the motorway bridge during the work. Westbound traffic will be detoured via Main North Road, Ohoka Road and Island Road
• The Tram Road on-ramp will be accessible throughout the work, and in particular during the weekday peak morning period
• During overnight off-ramp and Tram Road closures, access to the on-ramp will be available from the east approach (Main North Road) side only
• Drivers heading from Christchurch to Kaiapoi are encouraged to consider using Main North Road and the Old Waimakariri Bridge to access Kaiapoi to avoid disruption at the interchange.
