Along with a number of businesses from across the Stevenson Group, Stevenson Concrete have been supplying expertise and materials to a major new motorway project – the 4th lane extension from Market Road to Greenlane – for main contractor Downer.

This project continues Stevenson’s ongoing contribution to the development of Auckland’s infrastructure for nearly a century. Construction on the new 1.7km 4th southbound lane between the Market Road off-ramp and the Greenlane Interchange will increase capacity and help to reduce congestion across the central motorway system.

‘This is a complex project with many logistical issues,’ says Downer Project Manager Craig Fletcher. ‘The depth of experience and expertise across the Stevenson Group has assisted us in meeting challenges that have ranged from stringent site access and safety requirements to technical solutions which respond to the unique site and operating environment.’

‘Our ability to work collaboratively across our business to meet the requirements of Downer has been reinforced on this project,’ says Stevenson Account Manager Angela Purcell.

High durability concrete mixes were specifically designed for the project.


“Stevenson Concrete is delighted to be involved on this significant infrastructure project,” says General Manager David Lowe.

“We have been supplying a range of concrete mixes to the project, with strict requirements on the concrete specification and testing. High durability mixes have been specifically designed for the project.

“Constant communication and a close working relationship are essential on a project of this nature. We have enjoyed working with Downer as part of the team to ensure that all of NZTA requirements are met in full.”
