How about transporting yourself back to 1979? That was when the Northern Motorway stretched only as far as Sunset Road Overbridge.
Sunset Road Overbridge is more than just concrete and steel. It’s a silent witness to Auckland’s rapid growth.
Before interchanges and toll roads, the motorway ended abruptly here. Imagine driving expecting a smooth ride. Suddenly you are met by a set of traffic lights. The visibility was limited. It must have been a bit of a shock for drivers back then.
In 1984, a two-lane expressway extended the motorway to Greville Road. The Sunset Road Overbridge remained a key part of the route. It guided traffic towards Albany Highway.
Think about the changes this overbridge has seen. From a simple endpoint to a vital link in a sprawling network. The Northern Motorway is now 58 kilometers long. It boasts 17 junctions.
Initially, the Auckland Harbour Bridge Authority managed the motorway. This management extended from Fanshawe Street to the toll plaza. The National Roads Board took care of the section from the toll plaza to Northcote Road.
Consider the impact of the Northern Motorway’s construction. Large sections of Smiths Bush were destroyed. This bush was a remnant kahikatea and taraire forest.
Remember the “suicide lanes?” Tidal flow was introduced on the Harbour Bridge in the 1980s. These reversible lanes led to fatal collisions. A moveable barrier was installed in 1990. It separated the traffic flows.
In 1994, the expressway became part of the Northern Motorway. A new interchange was created at Upper Harbour Highway and Constellation Drive. This replaced the Sunset Road intersection.
The Northern Gateway Toll Road opened in 2009. It was the first automated toll road in New Zealand.
Even today, the Sunset Road Overbridge remains relevant. In fact, in recent years, it was the site of a police incident.
The Sunset Road Overbridge stands as a testament to progress. It has transformed Auckland. It connects communities. It facilitates trade.
It is a constant reminder of the city’s ever-changing landscape.
