Porirua drivers are being warned to expect night-time road closures, detours and lane restrictions this week as maintenance and upgrade work continues on key state highways.
NZ Transport Agency Waka Kotahi says work is planned on State Highways 1 and 59 between January 24 and January 30, with all timings weather dependent.
On State Highway 1, Transmission Gully will be closed northbound overnight for chipsealing. The closure runs between Linden and the SH58 interchange on Monday and Tuesday nights from 9pm to 7am. On Wednesday and Thursday nights, the northbound closure extends from Linden to Paekākāriki over the same hours. Traffic will be detoured via State Highway 59.
Southbound traffic on Transmission Gully will also be affected, with overnight closures between Paekākāriki and Linden from Sunday to Tuesday nights, 9pm to 4.30am, for chipsealing.
In addition, southbound lane closures remain in place during the day and night in several locations, including Battle Hill and Waitangirua, for paving, barrier removal and chipseal-related traffic management.
On State Highway 59, the old coastal route through Porirua, the northbound road between the Paekākāriki and MacKay’s interchanges will be closed during the day on Thursday from 8am to 5pm for power pole installation.
In Paekākāriki, drivers can expect altered lane layouts from Monday to Friday, 6.30am to 4pm, for a watermain upgrade. Stop-go traffic controls will also be in place south of Fisherman’s Table on Tuesday and Wednesday nights from 7pm to 4am for sign renewals.
Pukerua Bay motorists will face stop-go controls south of Gray Street on Tuesday night, 7pm to 4am, also for sign renewals.
Closer to Porirua, lane closures are planned at Paremata Roundabout and north of the Whitford Brown interchange on Wednesday night for streetlight pole replacement. The Titahi Bay southbound off-ramp will close briefly early Tuesday morning, from midnight to 3am, for the same work.
Waka Kotahi is urging drivers to allow extra travel time, follow posted detours and traffic management, and check for updates before setting off. All works may be delayed or rescheduled if weather conditions change.
