Mansel Drive and Woodcocks Road Upgrade, Warkworth
Mansel Drive 400
Project management, design, consenting, and construction management for a new collector road to service a bulk retail centre and retirement village. Design involved the upgrade of Woodcocks Road from a rural road to collector standard including infrastructure, widening, pavement conditioning, pedestrian footpaths, and retaining. Specific attention was required for the design and construction of pavements within variable and soft subgrade conditions. The newly formed road is intended to form part of the western collector, which helps alleviate traffic passing through Warkworth, along SH1.
