Five nights of road closures start this Sunday for State Highway 58, with storm repairs and maintenance works planned for the route.

The highway will have night closures from 24 to 28 May (Sunday to Thursday nights) between 9pm and 4:30am.

Contractors will be completing a wide range of tasks including flood repairs, general maintenance, and SH58 Safety Improvement Project works.

This includes scour and washout repairs, removing rockfalls, clearing vegetation, and clearing flood debris from culverts and drains ahead of expected wetter winter weather.

They will also complete repairs to wire rope safety barriers. So far this year there have been 10 barrier strikes where cars have crashed into them. Because they are proven to significantly reduce the risk of death and serious injury in road crashes, it is essential that they are maintained properly.

Night closures

Night closures are being used to complete the work as they are the most efficient and low-impact way of getting maintenance work done.

Traffic data shows that while State Highway 58 carries, on average, 20,000 vehicles every day between the Hutt Valley and Pāuatahanui, traffic volumes between 10 pm and 4 am are far, far lower – around 330 to 450 vehicles.

Completing road maintenance when fewer people use the route means the impact on traffic and the public is minimised.

Resident and business access/detour routes

Residents, business owners, business customers, and emergency services will have access through the closures at all times.

Hutt Valley drivers needing to access Porirua or State Highway 1 Transmission Gully will have to travel via State Highway 2 to Ngauranga and then use State Highway 1. People heading to the Hutt Valley will have to use State Highway 1, then State Highway 2.

This is a longer trip, and people will need to allow for extra travel time when the closures are in place.
