Auckland Harbour Bridge - Wind Records
Richard Young made this Official Information request to New Zealand Transport Agency
The request was partially successful.
From: Richard Young
Dear New Zealand Transport Agency,
I note that one significant safety reason quoted for denying people the ability to walk and cycle across the under-utilised Auckland Harbour Bridge is the strength, frequency and unpredictability of wind on the bridge. I assume that to reach this conclusion that Waka Kotahi has a significant data set related to wind.
Please can you therefore provide the last ten years of wind records for the Auckland Harbour Bridge in the possession of the Agency or your contractors. I understand that this data set would typically include the time/date stamped 15 minute interval, peak and mean wind speed and directions. If you have this data please provide it in an CSV or Excel file. If you do not have wind data in this exact format please provide the closest that you have to match this request for the longest period you have up to ten years.
Please also provide any reports/ emails/ correspondence over the last five years related to the assessment of wind risk to people walking and cycling across the Auckland Harbour Bridge.
Yours faithfully,
Richard Young

From: Richard Young
Dear Official Correspondence,
Thank you for you letter of 22/8. I note that you have not provided the 15 minute interval records I requested but instead only provided the hours, gust and 10 min mean for 1 hour periods when the wind speed exceeded 75km/h. As a matter of urgency please can you provide the information originally requested or confirm that you have no data for this.
The data you have provided states it is from an elevation of 67m, significantly higher than the highest trafficked level. Please therefore can you advise if you have any wind data at bridge deck level on the Harbour Bridge? Please also treat this request under urgency.
I note with interest that Waka Kotahi has not undertaken an assessment of wind risk to people walking and cycling across the Auckland Harbour Bridge.
Yours sincerely,
Richard Young
