The new expressway surface between part of Waikanae and Peka Peka will be upgraded to make it smoother and quieter.
Most of the recently completed 18km long Mackays to Peka Peka Expressway has open graded porous asphalt (OGPA), which reduces noise levels and creates a smooth driving experience, but the northern section has a chip seal surface which heightens noise levels and makes it a bit rougher to drive on.
A number of residents have been upset about the expressway noise in the northern section and have been making their views known to authorities.
Transport Agency highway manager Neil Walker said the agency had "listened to the concerns of residents about the additional noise the expressway traffic is generating, and is bringing forward planned re-sealing work, using low noise surface material".
"The aim is to start the resurfacing at the beginning of the next spring construction season, which will be November, at the earliest.
