Four pedestrian crossings, complete with traffic-slowing speed humps, are being installed along the lakefront retail strip within a stretch of about 100m.
Ms Nimmo is all for people crossing the road safely but thinks four crossings are too many and a waste of money, and will cause vehicles to bank up, forcing motorists to use Brownston St instead.
She has been wondering if ratepayers knew what was in store when the roadworks started, and has observed the steep humps are hazards for motorists, buses, stock trucks and ambulances, which have been bouncing over the top of them.
Only skateboarders would love the humps, she said, as they looked like an extension of the skate park.
Ms Nimmo was so annoyed she recently rang Queenstown Lakes Mayor Vanessa Van Uden, who promised to have a look when she next comes to town.
"There's four of them! What is the issue? If we had an issue with boy racers it would be totally different. But we don't.
The project could have been cut in half. Two would have made the same point," Ms Nimmo said.
Wanaka Community Board chairman Lyal Cocks defended the project, saying the crossings and humps were necessary to slow traffic.
"You can still drive through there. Just do it slower ... Yes, four might be over the top, but let's see how it works," he said.
The board had spent many years listening to the community's traffic concerns.
The Ardmore St roadworks are part of a bigger strategy developed in 2008 to remove Ardmore St's arterial status and divert traffic to Brownston St.
Much work was yet to be done, and it was just a pity the proposed Ardmore St and Brownston St roundabout had not been completed first so traffic could be diverted to Brownston St at the entrance to town, he said.
The $300,000 roundabout was crucial to the transport strategy but had been delayed because landowners and the New Zealand Transport Agency were still negotiating access, Cr Cocks said.
Cr Cocks asked for patience as the council rushed to finish a range of roadworks before the snow season started.
The Queenstown Lakes District Council decided to make Ardmore St a special-character road in 2008, when it released its wide-ranging $43.7 million Wanaka transport strategy.
The strategy responds to community concerns raised in 2002 that if nothing was done, Wanaka would become congested with traffic.
Brownston St will become the main cross-town traffic route well within 20 years. Changes to lakefront parking are also planned, but that works programme has not started yet.
