Project overview
A key north-south connection within Whenuapai, the upgrade of Trig Road will play an important role connecting the future Whenuapai business area to the state highway network via Trig Road’s east-facing ramps to State Highway 18.
New walking and cycling facilities over State Highway 18 will enhance travel choices to access Westgate, the Whenuapai business area and ferry services.
The proposed works includes:
-
widening of Trig Road to an urban arterial road including separated cycle lanes and footpaths
-
localised widening around the existing intersections with Brigham Creek Road and Spedding Road to accommodate proposed roundabouts, and localised widening around the intersection of Trig Road with Northside Drive to accommodate a signalised intersection
-
tie-ins with existing roads, stormwater ponds and culverts
-
the addition of an active mode bridge to the existing bridge across State Highway 18
-
batter slopes to enable widening of the corridor, and associated cut and fill earthworks
-
vegetation removal along the existing road corridor
-
other construction related activities required outside the permanent corridor including the re-grade of driveways, construction traffic manoeuvring and construction laydown areas.
