New Zealand: Authorites to close Lyttelton Tunnel in Lyttelton nightly until July 14

Event

Authorities are conducting deluge testing on the Lyttelton Tunnel 00:01-05:00 nightly until July 14. Officials will close the tunnel, a portion of State Highway 74 (SH74) that connects Christchurch and Lyttelton Port, during the works. However, workers will open the tunnel for 10 minutes every hour to permit some vehicles.

An increased security presence is likely near the tunnel to enforce traffic measures. The New Zealand Transport Agency has advised motorists to use alternative routes, though detours will extend travel time between the port and Christchurch. Delivery delays are possible until the work concludes.

Advice

Confirm traffic conditions on alternative routes before driving or routing shipments until the morning of July 14. Allow additional travel time between Christchurch and Lyttelton.
