Expect delays 22–28 November as roadworks affect SH1, SH59, SH58, and Transmission Gully routes around Porirua.

Porirua drivers are in for a week of delays and detours, with extensive roadworks scheduled across the region from 22 to 28 November. The work affects major routes including Transmission Gully, State Highway 1, SH59 through Porirua and Pukerua Bay, and SH58 into the Hutt Valley. All works are weather dependent and subject to change.

Transmission Gully will see both southbound and northbound lane closures day and night for summer maintenance, including stretches from Battle Hill to Rainbow Bridge and Pauatahanui to Waitangirua. Additional southbound work is planned near Waitangirua on Tuesday from 9am to 5pm.

In Tawa, SH1 will be impacted by paving works with night-time lane closures and altered layouts between the Takapu Road off-ramp and Westchester Drive.

Porirua and nearby communities face multiple disruptions on SH59. Teihana Road West in Pukerua Bay will be closed Monday and Tuesday during the day for power pole replacements. Stop/go traffic controls are planned in Paekākāriki and Plimmerton throughout the week for sign renewals, paving, and tree trimming. The Mungavin southbound on-ramp will close Sunday night, and the Titahi Bay southbound off-ramp will shut briefly on Monday night for streetlight work.

State Highway 58 remains under construction for the SH58 upgrade project. Nightly stop/go controls and altered lanes are in place from Judgeford to Transmission Gully. Whitby’s Spinnaker Drive side road remains closed due to a slip.

Drivers are encouraged to check the Waka Kotahi website for real-time updates and consider alternate routes to avoid delays.
