SH1 Tinwald Corridor Improvements – February project update from Waka Kotahi NZ Transport Agency

Work ramping up again

Work has now resumed on the project with our crews focusing on upgrades to the Viaduct and Graham Street.

Below we outline what work is coming up this year and what is left to complete on the project

SH1/Lagmhor Road/Agnes St intersection - a message from KiwiRail

Thank you for your ongoing patience as we continue with the upgrade of the Lagmhor Road level crossing and roading system.

We are working hard to complete this project, and your understanding is appreciated.

We are almost finished, with the physical works component of the project nearly complete. You will be aware that the new road layout, including flashing lights and barrier arms, is in place and the new traffic light poles have been installed.

The final piece of work is to install the LOC box which is in essence, the “brain” of the level crossing.

While a temporary solution is currently in place, which is allowing the level crossing to operate safely, this essential component is responsible for coordinating the barrier arms with the pedestrian gates and traffic lights.

We are expecting work on the programming, installation, and testing of the LOC box to be completed by early April. While it's being built and tested, you may not see much physical activity at the site because most of the technical work is completed off-site.

Traffic management at the SH1/Lagmhor Road/Agnes St intersection will be ongoing, as the system will not be fully operational until this work is completed.

Reminder of work under way

For the next few weeks, we’ll be working on Melcombe Street at the Viaduct with a road closure in place.

We’ll be installing a pedestrian crossing, new foothpath and completing pavement improvements.

Please look out for changes in traffic management and follow the signs on-site.

Pavement improvements are also being undertaken on Graham Street, at the intersection with McMurdo St.

The work is expected to be complete in early March and a road closure will be in place until then.
