Contractors dealing with the effects of heavy rains last month are also continuing to clear debris from parts of SH38 between Mangapapa and Frasertown and some delays can be expected.

Work at the two other major roundabouts already well under way, at Napier and Pilcher Rd near Maraekakaho and the SH2/Watchman Rd layout, is also being carried out with temporary speed restrictions in place.
