Auckland Harbour Bridge

Providing access across the Waitemata to Auckland’s North Shore, the Harbour Bridge is a landmark feature for Auckland and New Zealand. For 25 years, BCHF have continued to provide innovative structural upgrade designs to help keep it safe to use.


Today’s load demands on the bridge far exceed those of the original 1950s design, and over the years, several upgrades and maintenance works have been required to increase capacity, ease congestion and future-proof the bridge’s structural and seismic integrity. BCHF’s civil structures team delivered a number of critical interventions that have attracted international interest – including the seismic and wind retrofit in 1999, the truss bridge strengthening in 2006 to cater for increasing traffic loading, and strengthening the extension bridges in 2010 for future traffic load growth.
