Traffic switch to happen soon
The 27km long Transmission Gully motorway project reaches a significant milestone in mid-December, when all traffic is switched on to the new coast road connection.
On the evening of Friday December 14 and weather permitting, SH1 south and north bound traffic will be switched onto the new coast road connection between Mackays Crossing and Paeka¯ ka¯ riki.
CPB HEB Construction director Justin Redelinghuys said the switch marks the next big step in a string of changes and activity on the SH1 network.
“Progress at Paeka¯ ka¯ riki, Pauatahanui and between Porirua and Linden has become much more visible to the public.
“We are beginning to see just how far the project has come since we started construction and it’s an exciting time.
“Although it will be temporarily used as a new section of SH1, the new coast road is one of the first finished pieces of road along the project that can not only be seen but also used.”
While the new road will open in midDecember, there is still some finishing work to get done before it is opened to the public.
Applying the final chipseal surface and line-marking are the last steps before the road is complete and the switch can be made.
This work is weather dependent. New lighting is also going up along the new route.
To reduce possible confusion for road users, the lane layout that was implemented for the Mackays Crossing Update has remained in place in preparation for the switch on Friday December 14 and will continue to allow for further work in the area.
Once Transmission Gully opens in 2020, the coast road will then become the new connection between Mackays Crossing, Paeka¯ ka¯ riki township and the Centennial Highway.
The traffic switch will require a significant set up, starting about 7.30pm on Friday December 14 or when traffic flows allow.
It is expected to be completed and open to the public by 5am on Saturday 15 December. There may also be some work at nights to fully complete all the work.
“Switching traffic before the weekend will allow us to monitor the new road and address any issues that may arise before week day peak traffic on the morning of Monday December 17.
“There will be a smooth connection onto the new coast road and the switch will be heavily sign posted with large concrete barriers in place as a safety precaution for both our staff working onsite and motorists.”
The speed limit on the new coast road will be 80kmh.
