Simeon Quay - half bridge replacement



We are replacing an aging half bridge with a new retaining wall to support the road on Simeon Quay.


We maintain our bridges and retaining walls across the city to make sure they are safe and work effectively.


South side of Simeon Quay - adjacent to number 2 Simeon Quay, Lyttelton.


***DAY WORKS: February 2021 to mid December 2021. Monday to Saturday, 7am to 6pm (weather/site condition dependent).
***NIGHT WORKS: February 2021 to mid December 2021. Sunday to Friday, 7pm to 6am (weather/site condition dependent).


The contractor is Hunter Civil Ltd. Phone 03 381 7094, Monday to Friday, 7am to 6pm.


There has been a further delay to our work on Simeon Quay, which has had an impact on the project’s expected end date.

The work is now due to finish mid December 2021, not August as earlier communicated – although this is dependent on the weather and whether any further unforeseen issues arise.

The delay is due to a landslip occurring below the construction area of the new retaining wall. This slip needs to be repaired and stabilised prior to the completion of the retaining wall and road works.

The hours of work and impacts remain the same.

Work continues to be undertaken predominately on day shifts and night shifts will be required for some roading activities.

Impact of work:

  • There will be some noise disturbance.
  • Some evenings Simeon Quay will be reduced to one lane, with stop/go traffic management in place. This is likely to cause delays overnight, particularly for west bound traffic coming from the tunnel and heading along Simeon Quay.
  • A temporary queueing route will be set up for west bound traffic (heading towards Governors Bay and Naval Point), in case of heavy queueing demands.
  • The queueing route will be along London Street, between Dublin and Canterbury Streets, on night shifts only – when traffic may be reduced to one lane.
  • Some on-street parking will be restricted for safety reasons.

The Simeon Quay work is part of the renewal programme for our bridges and retaining walls across the city, which ensures their safety and effectiveness.
