At Skjoldastraumen in Tysvær, a narrow tidal strait connects the outer coast to the inner Skjoldafjorden. The currents here were so strong and unpredictable that for centuries, boats entering or leaving the fjord risked being swept sideways or capsized. The solution, completed in 1908, was to canalise the western channel and build a lock, one of very few saltwater locks ever constructed in Norway.
The lock is 42 metres long and 6.9 metres wide, with a depth of 3.5 metres. It has gates at both ends so it can function regardless of which direction the tide is pushing. The canal itself stretches 460 metres, and a bascule bridge over it folds up to let boats with tall masts pass through. It is the only saltwater lock in Norway that has been in continuous use since it opened.
You can watch the lock in operation from the roadside. Pleasure boats and smaller vessels still use it regularly, especially in summer. The mechanical simplicity of the system, gates, water, gravity, makes it satisfying to watch even if you have no particular interest in maritime engineering.
