The single-lane Kopu Bridge was replaced by a two-lane bridge in 2011.
To improve travel times and safety along State Highway 25 to and from the Coromandel Peninsula.
The new bridge has improved safety and travel times across the Waihou River at Kopu. It has also boosted the region’s economy and tourism by making it a lot easier for freight and holiday makers to access the Coromandel Peninsula
The NZ Transport Agency has replaced 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 high volumes of visitor traffic. It is also an essential link for emergency services.
The Kopu Bridge replacement project includes:
The 42.8m central span of the new bridge is the main navigational channel for boats. The underside of the central span is 6.5m above mean sea level, providing sufficient height for large river boats to pass under.
The existing bridge is classified as a Category 1 historic structure by the Historic Places Trust.
The new two-lane Kopu Bridge was officially opened by Prime Minister John Key on Saturday, 10 December. A public bridge walk was held the same day and attracted 8000–10,000 people.
The bridge opened to traffic on Monday 12 December 2011, approximately six months ahead of schedule. Finishing works on other parts of the project continued until early 2012.
