Traffic has been getting worse and is reduced to a crawl along Vipond and Whangaparaoa Roads and Hibiscus Coast Highway to the motorway in the morning peak.
The problem has been getting worse over the last couple of weeks but as yet it is unclear what is going on.
Auckland Transport says it is definitely not caused by its work on building the infrastructure for Dynamic Lanes, with traffic restrictions there only occurring outside peak hours.
The next phase of work on the Dynamic Lanes is due to begin this evening (November 15), which will see detours and road closures on some nights from 7pm–5am.
The work involves laying cable, installing the gantry system and LED lights and is expected to take 3–4 weeks (until around December 14).
CSL Infrastructure electrical services manager Kahn Day says contractors will start the setup at 7pm and the road will be closed to all except residents and emergency vehicles. The roadwork itself will begin around 8pm.
A notice mailed to residents along the affected piece of road says to expect delays.
Meanwhile accidents, work on the highway and flooding in Silverdale have been put forward as suggestions on various days to explain the slowing up of traffic on the peninsula. Hibiscus Matters has sent a second enquiry to Auckland Transport and its team is looking into it.
Any updates will be added to this story when received.
