The desire for a permanent connection across the Limfjord at Aggersund dates back to the early 1900s. In the mid-1920s, citizens in Løgstør reduced a selection, which appeared with a number of suggestions for a bridge. However, the initiative stranded controversy about the alignment and funding. In 1936, the idea was resumed by the Ministry of Employment and Social Affairs and the Ministry of Transport as a possible employment measure, and in 1939 the construction of the bridge, which was funded by Aalborg, Hjørring and Thisted Amter, began. The bridge was projected by Christen Ostenfeld. The initiation took place on 18 June 1942. The bridge cost about 3.5 million DKK. During the German occupation of Denmark, the bridge was strategically important for the German shipments of crew and equipment to and from Norway. Therefore, a military support point was built in 1943-44, consisting of 11 concrete plants on the north side and 6 on the south side. In addition, minefields and other types of barriers were introduced. Two large Flak bunkers on the south side and one on the north side are still available and are available. The other smaller bunkers have either been removed or located in a private area without public access. In 2000, the Aggersund Bridge beams were strengthened, increasing the carrying capacity of the bridge. Coordinates: 56°59′58″N 9°17′38″E﻿ / ﻿56.9995°N 9.2940°E﻿ / 56.9995; 9.2940
