Bridges and Locks

Trollhätte canal is 82 km long. Of this, 10 km is a dug and blasted channel, the rest is a natural fairway in the Göta River. On the route you pass 12 bridges, 3 of which are fixed


The difference in level of a total of 44 meters is managed by six locks, one at Lilla Edet where the difference is 6 meters, four locks at Trollhättan with a total difference in level of about 32 meters and one at Brinkebergskulle of about 6 meters.

The locks are of modern construction with electrical/mechanical operation of hatches and gates. Double bottoms mean that the water is distributed evenly over the entire lock. It provides quiet water movements during both filling and emptying.

A sluice requires 8000-12000 m3 of water. The water depth in the fairway is at least 6.3 metres. In the locks, the depth of the threshold is 5.7 meters at the lowest water level. There are a large number of fairway markings in the canal and river.

The distance from the water surface to the lowest point of the lines is 27 meters.
