On Tuesday 21 October 2008, State Highway 1 will be closed to traffic through the Brynderwyn Hills from Brynderwyn in the south to Waipu in the north from 6.30am to 7.30pm.
The closure is required for emergency resurfacing work at the southern end of the highway.
During the closure detours will operate in both directions and will be fully signed.
Northbound traffic will be diverted off SH1 at Brynderwyn onto SH12 and then to the Paparoa-Oakleigh Road to rejoin SH1 at Oakleigh.
Southbound traffic will be diverted off SH1 in Waipu at Shoemaker Road to Waipu Cove, Mangawhai Village and on to Kaiwaka-Mangawhai Road to rejoin SH1 at Kaiwaka.
Each of the detours is slower and about 20km longer than the SH1 route. Drivers should therefore allow an extra half to one hour for their journeys. To minimise delays, drivers are asked to make only essential trips while the work is being done.
New Zealand Transport Agency acting Regional Manager, Tommy Parker, says the work is purposely being done before Labour Weekend when traffic on SH1 through the Bynderwyn Hills is at its peak.
Mr Parker says further resealing work will be carried out earlier next year as part of an ongoing safety programme. This will include the erection of a 30m long guard safety rail on the waterfall section of SH1 towards the southern end of the Brynderwyn Hills.
