About the project

The staggered-T intersection of Onkaparinga Valley Road, Tiers Road and Nairne Road in Woodside has been identified as a key location in the Adelaide Hills that would benefit from safety upgrades.

The draft concept design aims to deliver:

• a new pedestrian crossing on Onkaparinga Valley Road near the Woodside Library that will provide safer pedestrian and cyclist movements
• increased safety for all users of the junctions
• improved functionality and access for heavy vehicles which includes an extension of painted medians to provide greater separation of general traffic.
