Several new bridges of considerable length connected Norrmalm to the islets west and east of it; Blasieholmen, at the time still an islet, was connected to the mainland by a bridge called Näckenströms bro, and northward to present day Strandvägen by Stora Ladugårdslandsbron, a 190 meters bridge on poles; and to the west a bridge connected Norrmalm to Kungsholmen over Blekholmen, a now non-existent islet.
