North South Junction improvements project

The North-South Junction (NSJ) Improvement Project near Wellington was a large and complex multidisciplinary project delivered in a very busy metro and freight corridor. The project involved enlarging tunnels, large scale slope stabilisation works, improving the track alignment within difficult geographical constraints and upgrading other associated railway infrastructure. The end outcome of this extremely challenging project was to successfully increase the capacity of one of New Zealand’s key rail bottlenecks. The $21.5 million project was completed on time and with an exceptionally low injury rate. This paper will describe the innovative engineering inputs and construction methods utilised to do this, the challenges faced and the benefits it delivered in the wider NZ transport context.
