Work to improve road safety and monitor heavy vehicles on Wellington’s state highway network is stepping up a gear.

Early next month, contractors will begin preparing SH1 and SH59 for installing weigh-in-motion systems for the Mackays Commercial Vehicle Safety Centre (CVSC) being built on the Kāpiti Coast

They will be installed in three locations: one on SH1 Transmission Gully, one on SH1 Raumati Straights, and another on SH59.

This work will prepare the road for the upcoming installation of weigh-in-motion technology. The actual scale installation will be a much quicker process and will be done at least 20 days after the pavement work.

Contractors will complete the initial works as quickly as possible. They will be on-site from Tuesday 3 March until Friday 13 March.

Because the sensors have to be installed into the road, work from Tuesday 3 March to Tuesday 10 March will require weekday single-lane closures, 24/7, on the northbound and southbound lanes of SH1, and an onramp closure at the SH59 Paekākāriki interchange.

Once contractors have completed preparatory works on SH1, they will move to SH59, south of the Paekākāriki interchange, to complete similar work for another weigh-in-motion system planned for this location.

This will require stop/go traffic management and is expected to take place between Thursday, 12 and Friday, 13 March.

Lane closures will be in place 24/7 on weekdays only. They will affect traffic flow and cause travel delays. Drivers are encouraged to factor this into their travel plans.

Because this work is weather-dependent, schedules may change at short notice.

More information

These weigh-in-motion systems support the new Commercial Vehicle Safety Centre (CVSC) being built at Mackays Crossing.

CVSCs (formerly known as weigh stations) help ensure heavy vehicles are safe and compliant by checking weight, road user charges, certificates of fitness, and driver logbooks.

Once installed, the system will weigh heavy vehicles as they travel to and from Transmission Gully and SH59. If a vehicle appears to be overweight, it will be directed to the Mackays Crossing CVSC for further checks.

This is essential safety work that helps keep all road users safe by identifying potentially overloaded vehicles, while allowing compliant operators to keep moving without unnecessary delays.
