Moelva (Agder)
Moelva is a river in the municipalities of Birkenes and Lillesand in Agder, Norway. It originates from a hill south of Tveide in Birkenes and empties into the Tingsakerfjord, east of the town of Lillesand. Large parts of the disused, former railway Lillesand-Flaksvand Line followed the river bank.
An old stone bridge is still located by Helvetesfossen. It was restored by the Norwegian Public Roads Administration in 1993.
