Alfred Street is a one-way road that runs between Princes Street and Symonds Street in the heart of Auckland University. Bartley Consultants and the Auckland Road Maintenance Alliance consortium of MWH, Leightons and Blacktop Construction were tasked with upgrading Alfred Street to address concerns about the condition of the road pavement, road drainage and pedestrian facilities. This all needed to be achieved working in close proximity to a significant number of protected street trees that line each side of the street.
Bartley Consultants were responsible for developing a road pavement design that would achieve a 25 year design life, a geometric design that allowed the road level to be raised (thus minimising excavation near the trees), a paving design for the footpath areas, and drainage improvements to reduce surface water issues.
This project, which was implemented in early 2011, has significantly improved the quality and amenity value of this section of road.
