Waka Kotahi NZ Transport Agency is advising motorists that SH1 southbound from Ellerslie Penrose to Mt Wellington and Penrose Road will close from 9pm tonight to 6am tomorrow in order to carry out emergency repairs to the Penrose Road overbridge following a truck strike earlier this afternoon.
Southbound traffic will be detoured from SH1 at the Ellerslie Panmure interchange to Great South Road until Mt Wellington.
A signposted detour for northbound traffic into Penrose Road will be in place along Great South Road, onto Ellerslie Panmure Highway, Ferndale Road, Panorama Road and back onto Penrose Road.
A signposted detour for southbound traffic into Penrose Road will be in place along Great South Road onto South-Eastern Highway, Carbine Road, Waipuna Road and back onto Penrose Road.
The SH1 southbound closure may re-open to two lanes only once the works are completed and the props are installed, allowing the concrete to reach the required capacity.
Waka Kotahi thanks motorists in advance for their patience and understanding as we carry out these important repairs.
