A section of the main road from Fernhill to Queenstown has subsided after a "significant" burst water main caused havoc yesterday afternoon. On Fernhill Rd, the water appeared to be flowing underneath the asphalt, causing the foundations of the road to subside outside the Heritage. If they hadn’t stopped it when they did, my assumption is it would have been a lot worse in terms of property damage." Part of Queenstown’s Fernhill Rd subsided yesterday afternoon after a rising water main broke. Orbus was not able to travel up or down Fernhill Rd; instead, buses were travelling along the Glenorchy Rd, to Sunshine Bay and Fernhill.
