Project overview

SH23 is classified as a high-risk rural road. We have divided the safety improvements into three sections to review.

Section 1 – between Hamilton and Highbrook Way.

Section 2 – between Highbrook Way and Waitetuna (this section is still being analysed).

Section 3 – between Waitetuna and Raglan.

Suggested safety improvements include shoulder widening, rumble strips, side safety barriers, widened centrelines and minor intersection improvements. We are also having a look at how speed is managed along this route.

Estimated project costs

Section 3 – $10 million between Waitetuna and Raglan.
