The current intersection layout comprises a T priority-controlled intersection with insufficient capacity for projected future traffic growth, and a significant right turning crash rate. The intersection is ranked among New Zealand�s 100 high risk intersections listed by New Zealand Transport Agency (NZTA).

To resolve significant safety concerns and to ensure that the intersection configuration will be able to accommodate future projected traffic volumes, Auckland Transport proposes to upgrade the Coatesville-Riverhead Highway / Dairy Flat Highway Intersection. The intersection upgrade proposal involves: � Redesign of the intersection to include raised median islands and a roundabout.

Full description

� Widening the road carriageway to provide for the placement of the roundabout and four lanes from the roundabout to Dairy Flat highway, and three lanes from the roundabout to Coatesville-Riverhead Highway. � The road carriageway footprint has been designed to include future provision for cycle lanes that may be integrated with wider cycle networks.

� New mechanically stabilised earth (MSE) walls / batter slopes beneath the road carriageway to reinforce / support the road carriageway alignment and roundabout configuration, particularly where the new road alignment extends beyond the crest of adjacent slopes in some locations.

� An increase in total impervious area, the placement of catch pits in the proposed upgrade area, relocation of two storm water outlets, and installation of raingardens for storm water treatment. � Earthworks involving approximately 6,270m2 cut and 7,309m2 fill over an area of 9,328m2 to construct the new intersection and
