On the north side of the fjord is Norre Sundby, connected with Aalborg by a pontoon and also by an iron railway bridge, one of the finest engineering works in the kingdom.
The main lines in Jutland run (a) along the eastern side north from Fredericia by Horsens, Aarhus, Randers, Aalborg and HjOrring, to Frederikshavn, and (b) along the western side from Esbjerg by Skjerne and Vemb, and thence across the peninsula by Viborg to Langaa on the eastern line.
