Early work to construct a new interchange connecting Pāpāmoa East with the Tauranga Eastern Link Toll Road is expected to get under way on August 1.
There will be a one-lane closure heading eastbound towards Paengaroa for up to five days to install a permanent guard rail on the seaward side of the toll road, Tauranga City Council said on Tuesday.
There will be a temporary maximum speed limit of 70km/h through the worksite.
Council project manager Wayne Troughton said the lane closure was expected to have minimal impact on travel times.
Once the steel barriers for the guard rail were in place, the construction of stormwater culverts, including one under the toll road, would begin in mid-August.
