Regular users of The Terrace Tunnel need to be ready for two weeks of night closures network.
Work begins this Sunday (19 May) on upgrades of lighting in The Terrace Tunnel on State Highway 1.
Work crews will install over 1,100 new LED lights in the tunnel during two weeks of night closures.
The installation will be done alongside regular maintenance work and requires the tunnel to be closed while the work is done.
The Terrace Tunnel will be closed to all traffic on Sunday to Thursday nights, 9 pm to 4:30 am, from 19 to 30 May. Alternative dates are planned for June if bad weather delays the project.
The new LED lights will help future-proof the tunnel and improve its resilience and reliability. Because they are LEDs, they will also reduce power use.
The lights will be replaced progressively, with old lights switched out for new, allowing the tunnel to remain well-lit when open to traffic during the day.
Work crews will also make the most of the closures to carry out other important work. This includes upgrading electronic signs at the tunnel’s southern end.
The closure will require drivers to use alternative routes to access and leave the CBD. This will mean extra travel time, and drivers should plan their trips accordingly.
NZTA/Waka Kotahi and the Wellington Transport Alliance want to thank the public for their patience and cooperation while this essential state highway maintenance work is underway.
