The Triple Bridge is decorated with stone balusters and stone lamps on all of the three bridges and leads to the terraces looking on the river and poplar trees. It occupies a central point on the east-west axis, connecting the Tivoli City Park with Rožnik Hill, on one side, and the Ljubljana Castle on the other,[125] and the north-south axis through the city, represented by the river. It was enlarged in order to prevent the historically single bridge from being a bottleneck by adding two side pedestrian bridges to the middle one.
