Tararu Stream Bridge Replacement |
|
| SH25
|
|
| Over Tararu Stream at Tararu village, just north of Thames on SH25.
|
|
| Purpose: | To help protect the area from flooding as part of the Coromandel's *Peninsula Project |
|---|---|
| EstimatedCost: | $5.1M |
| Start Date: | Construction began in May 2008 |
| End Date: | Approximately mid December 2009 |
| Location: | Over Tararu Stream at Tararu village, just north of Thames on SH25. |
| Engineering Features: | The current bridge can handle less than half the volume of water that comes downstream in a major storm. The new bridge will be wider, safer and built to ensure it has the capacity to allow for much larger volumes of water, as well as the large amount of debris such as tree branches that are carried downstream during floods. Once completed the flow from even a '100-year flood' will be able to pass underneath the bridge. A significant stream retaining wall has been built to smoothly direct the stream under the bridge. This wall has been built to accommodate the very large bed scour depths of up to 5m that occur during flood flows. |
| Interesting Facts: | *Peninsula Project is a partnership between Environment Waikato, Thames-Coromandel District Council, Department of Conservation and Hauraki Maori Trust and involves an integrated multi-agency approach to managing the flood risk on the Thames Coast. The NZ Transport Agency is also replacing the Te Puru Stream Bridge, approximately 11km north of Thames on SH25, as part of the Peninsula Project. |
