One of the main aims of the Castle Hill Main Street project in 2010 was to beautify a stretch of Old Northern Road running through the centre of the Castle Hill shopping precinct. Works included new paving, seating, lighting and a series of community spaces.

Alpine Nurseries was awarded the pre-grow contract to supply mature trees, shrubs and groundcovers in July 2010. Planting was completed in April 2011 and all of the plants are showing great signs of vigour which has helped to realise the initial vision of the project.
