The German transporter bridge
at Osten is built over a dock dating back to 1815. The bridge covers a distance of 79 metres, and the towers are 35 metres high. It was inaugurated in the autumn of 1909, and one year later ticket offices were built near the bridge. At the present time this bridge belongs to the regional government, being one of the main tourist attractions in the area.
