Living on Borrowed Time - Bridge 194

Over my last few trips to Dunedin I spotted some activity around the old wooden bridge at Goodwood. My interest was further raised last week when I saw a large crane on the north side of the Pleasant River. While I couldn't stop to have a look at the time, I managed to get away from the house for short time to explore and see what was happening.

Arriving at Goodwood I turned off State Highway 1 onto Goodwood Road and then on Brooklands Road. It wasn't long until the bridge and the construction site came into view.

Bridge 194 is a traditional New Zealand railways beam bridge made up of three and five pile piers and 12 spans of steel and wooden beams. The bridge carries the Main South Line over the Pleasant River at Goodwood. 

Goodwood is located about halfway between the Otago towns of Waikouaiti and Palmerston and has the claim to fame as the location where the railway line between Christchurch and Dunedin finally met in 1878.

While the Pleasant River was nice and calm today, the river rapidly rises and floods if the area has any significant rain. Having a closer look at the bridge, you can see that it's taken a beating over it's many decades of service and is due for replacement.

With easy access and the thought that this bridge and many like it are quickly disappearing, I decided to get some detail shots of the structure.

To help get construction material to Goodwood, KiwiRail ran a special train made up log wagons carrying pile casings to the HEB Construction site.

While it's sad to see traditional NZR infrastructure like this bridge disappearing, it is good to see money being invested to improve and upgrade Aotearoa's rail network.

Since I pass this site a lot, I'll make sure to keep you up to date with the challenging work of building a new railway bridge while keeping the line open for traffic. 

And that's about it.
