Completion of the project "SH1 Porirua to Johnsonville"

The 6km of ducting for the installation of new ITS infrastructure on SH1 between Porirua and Johnsonville has now been completed.

Our trenching machine TRS300 performed at night with one traffic lane closure opening a narrow trench – 650 x 150mm. As expected, the ground conditions were difficult, but our rock saws performed better than expected.
