Detours will be in place between the Tawa and Mungavin Avenue interchanges.

The road will reopen at 5am tomorrow, but then will close again overnight tomorrow and on Tuesday night.

The four-lane, 27-kilometre Transmission Gully highway was supposed to open tomorrow, but has been delayed by construction supply shortages and Covid-19 restrictions.
