NZ Transport Agency Waka Kotahi | 21 May 2025 12:43pm | Nelson and Marlborough
People travelling between Blenheim and Christchurch can expect to see more road works on State Highway 1, Weld Pass over the next three weeks.
Work will be underway on weekdays from Monday, 26 May, to Friday, 13 June, between 7 am – 5 pm.
Because the road over the Weld Pass is narrow, and because of the size of machinery being used, stop/go traffic management and a 30 km/h temporary speed limit will be in place while this work is underway. Road users should expect delays of up to five minutes.
Contractors will be replacing a concrete dish channel. They will remove the existing channel, prepare and install a new channel.
Improving and repairing drains helps prevent water damage to the road and reduces the need for bigger and more expensive road repairs in the future.
