Drivers in Porirua and along key Wellington routes can expect a series of overnight closures and lane restrictions this week, with maintenance, resurfacing and upgrade works scheduled across Transmission Gully, State Highway 58 and central city corridors.
The works begin Monday and continue through to Sunday, mostly taking place overnight to limit disruption. Detours and stop go traffic controls will be in place in several locations.
Transmission Gully and Tawa area will see multiple closures early in the week. On Monday and Tuesday nights from 7pm to 5.30am, northbound lanes will shift for pavement quality testing, while the southbound off-ramp at Tawa to Westchester Drive and Grenada Drive will be closed.
Further southbound closures are planned Wednesday and Thursday nights between 9pm and 4.30am for resurfacing just south of the Tawa off-ramp. Additional lane closures for drainage maintenance will take place Sunday and Thursday nights near Johnsonville.
Several on-ramps and off-ramps around Johnsonville and Newlands will also close overnight, including the Johnsonville southbound on-ramp on Tuesday and the Newlands southbound off-ramp on Thursday. A series of resurfacing works will affect connections between Johnsonville and Newlands the same night.
In central Wellington, multiple tunnel closures are scheduled. The Terrace Tunnel will close Tuesday night for streetlight pole replacement. The Arras Tunnel will close Monday night for resurfacing, followed by the Mt Victoria Tunnel on Wednesday night for general maintenance.
Cobham Drive in Kilbirnie will be closed northbound Tuesday night between Troy Road and Evans Bay Parade, while Wellington Road will close northbound Sunday night for paving. Additional paving works are planned at the southern end of Coast Road in Pukerua Bay on Wednesday night.
State Highway 58 through Judgeford will also be affected, with alternating lane closures Sunday and Monday nights for streetlight replacements between Moonshine Road and Flightys Road. Ongoing stop go traffic controls and altered layouts remain in place day and night as part of the wider SH58 project.
During the day, drivers in Pukerua Bay should expect stop go controls between 7am and 5pm north of Airlie Road for drainage works.
