Ms Field, who usually travels along Nixon St to get to work, has been travelling along Deveron St and Mill Rd since the roadworks started.
"It definitely takes longer. At least double the time," she said.
Whangarei District Council project manager Mark Seakins said work to prepare the site for the road widening and the upgrades at the Mill Rd and Nixon St intersection was almost complete.
"We have upgraded the drainage system and are undergrounding the power and telephone wires. The next stage of the construction is to construct the road pavements. It is important that this pavement work is done in the right weather [temperature and dryness] so it is programmed for spring."
Mr Seakins said when Nixon St closed again in September the current detours would be reintroduced.
Ms Field said despite the congestion caused by the roadworks, having four lanes along Nixon St would be worth the disruption.
