# Sognefjord Span

The Sognefjord Spans are the second, third, and fourth longest spans in the world situated east of Hermansverk, Norway and are part of different powerlines. As Sognefjord Span is a deep valley the pylons of these spans are not taller than ordinary pylons. In order to avoid any too close approaches or contacts between the conductors, each is mounted on a separate pylon at the end of the span, which is built as a steel framework tower.

## Span 1

This span is part of the powerline between Hermansverk 61°10′49″N 6°51′53″E﻿ / ﻿61.18028°N 6.86472°E﻿ / 61.18028; 6.86472﻿ (Hermansverk) and Vikøyri 61°04′50″N 6°35′13″E﻿ / ﻿61.08056°N 6.58694°E﻿ / 61.08056; 6.58694﻿ (Vikøyri) and was built in the 1950s.
