The river beside Vadfoss has no clear name due to the fact that it changes names several times along its length, but it is often referred to as the Kragerø
watershed estuary or sometimes the Kragerø River (see the
Gallery section for a graphical representation of its many names). In general terms, it is the river stemming from the lake
Toke and leading out to the
Kilsfjorden. The main road serving Vadfoss is
Norwegian county road 38, which extends north across the river Kammerfosselva to connect onto the
European route E18 highway to the northwest and the road also heads southwest towards the
town of Kragerø. County Road 38 runs concurrently with County Road 363 through Vadfoss. County Road 363 splits off from County Road 38, just northwest of Vadfoss and then heads west towards the village of
Kil and it also splits off from County Road 38 on the south side of Vadfoss and heads east into
Helle. In 2008, the long Vadfoss Tunnel was built just north of the Vadfoss Bridge on the main road, eliminating the need to take the longer and more residential Sannidalsveien. Vadfoss historically had a
train station along the now defunct
Kragerø Line that primarily transported
lumber and passengers. In 1989, the whole line south of Sannidal Station in
Kil was torn up in order to make way for the new main road. Elements of the rail line still remain however, including the bridge across the river and the original station building from 1927, which is now used as a
visitor center and
bus depot. ==Industry==
