SH25 Kopu Bridge Replacement

The NZ Transport Agency (NZTA) is replacing the Kopu Bridge on State Highway 25, south of Thames. This route is considered strategically important in the National State Highway Network. It is the preferred link between Auckland and the Coromandel Peninsula, and carries seasonally high volumes of visitor traffic. It is also an essential link for emergency services.

Beginning of content

The existing one-lane bridge built in 1927-28 remains structurally sound, but does not have the capacity to cope with peak flows during holiday periods without causing significant delays. A modern, two-lane bridge will be constructed immediately upstream from the existing bridge with separate cycle and pedestrian facilities.

The new bridge will improve traffic capacity, reduce delays and meet modern safety and structural standards.

Timing

Construction started in July 2009 and is programmed to be completed by mid 2012.
