The Trans-Alaska Pipeline System (TAPS) has some parts raised on stilts to prevent the permafrost from melting. The pipeline, which stretches approximately 800 miles from Prudhoe Bay in northern Alaska to Valdez on the southern coast, was constructed with elevated sections in areas where the permafrost is particularly sensitive to temperature changes. By raising the pipeline on stilts, it helps to keep the ground underneath cooler, reducing the risk of permafrost thaw and potential damage to the pipeline.

Hi Austin!

The pipeline is called the Trans-Alaska pipeline. However, despite the stilts meant to stop the permafrost melting, the pipeline has radiators positioned along it to stop the oil inside from freezing. The stilts also protect the pipeline in event of earthquakes.

Hope this helps!

The Trans-Alaska Pipeline were built on an elevated support system that keeps the pipe about six feet above the ground.

The pipeline is the Trans Alaskan pipeline. Although insulated and on stilts it has radiators at regular intervals along it, to maintain the warmth of the crude oil to keep it flowing. It is also on silts to allow migrating Caribou to travel North during summer months and also to allow the pipeline to move during earth tremors, as Alaska is in an area prone to earthquakes.
