Whispers of the past echo around us as we stand before the Kelburn Viaduct. This impressive structure isn’t just a way to get from one place to another. It is a testament to Wellington’s growth.
The Kelburn Viaduct represents an important chapter in Wellington’s history. It connects Kelburn, Karori, and Northland to the city. Imagine Wellington in the late 19th and early 20th centuries. The city was growing fast. People needed more space to live. Suburbs like Kelburn were perfect but there was a problem. The hilly terrain made access difficult.
That’s where the original Kelburn Viaduct came in. Around 1900, a wooden viaduct was built. It was designed by James Fulton. He also designed the Kelburn and Karori Tramway. The tramway was the front gate to these suburbs. The viaduct was the back gate. This made these suburbs popular and affluent.
By the 1920s, the wooden viaduct was showing its age. It had been repaired many times. People questioned its safety. It could no longer handle the traffic. Despite the economic challenges of the Great Depression, Mayor G.A. Troup started a program to improve transport. In 1929, it was decided to replace the old viaduct. City Engineer G.A. Hart created the designs for the new one.
The new Kelburn Viaduct was to be a pylon design. It would be 350 feet long and 32 feet wide. This allowed for a 22-foot roadway and 5-foot footpaths on each side. Ratepayers authorized 24,200 pounds for the project. Mr. W. Hodges’ tender of 21,439 pounds was accepted in December 1929. He would construct a reinforced concrete structure.
Construction began in 1930. The first few months focused on work below ground. Heavy excavation was needed to reach solid ground for the concrete pier foundations. Once the foundations were in place, the structure rose quickly. It was built with three concrete girders. These rested on two concrete piers with steel reinforcing throughout. By December 1930, the central arch was complete. People admired the attractive balustrades, noting their artistic finish.
The new concrete Kelburn Viaduct officially opened on May 2nd, 1931. The Mayor, Mr. G.A. Troup, cut the ribbons. But the opening wasn’t without drama. There was a dispute over the bronze plaques. The engineer wanted a simple plaque. It would read: “Wellington City Council. Kelburn Viaduct, constructed 1931.” The Mayor wanted a more elaborate design with his name on it.
Eventually, a compromise was reached. Two plaques were made. One followed the original design. The other bore the name of the Mayor and all city councillors. The final Kelburn Viaduct was built of reinforced concrete. It was 234 feet long between the abutments. It had three spans of 72 feet, 74 feet, and 72 feet. The deck was 65 feet above Glenmore Street. The viaduct provided an important link. It connected Upland Road and Glenmore Street. It also connected Kelburn, Northland, and Karori.
Since 1931, the Kelburn Viaduct has seen few changes. In the late 1930s, there were calls to alter the balustrades. This was due to suicides and accidental deaths. However, this didn’t happen until 1972 when the original balustrades were replaced. The piers and entrances remain unchanged.
Today, the Kelburn Viaduct remains an attractive and well-engineered structure. It still links Kelburn, Karori, and Northland to the city. Its monumental appearance and well-proportioned design give it significant aesthetic value. The viaduct reflects Wellington and New Zealand’s history. It shows how infrastructure was developed to deal with difficult terrain. It also facilitated suburban expansion.
Take a moment to appreciate the Kelburn Viaduct. It is more than just concrete and steel. It’s a symbol of Wellington’s growth, innovation, and connection to its surrounding suburbs. It’s a reminder of the people who built this city. Their vision shaped the landscape we see today.
