Klappbrücke Nehringen, Wooden road bridge in Grammendorf, Germany.

The Klappbrücke Nehringen is a 44.50-metre wooden bascule bridge over the Trebel, carrying the road between Nehringen and Klein Methling. Its roadway is 3.50 metres wide, narrowed to two metres on each bank by concrete sections; the span is seven metres and the total area 267 m².

A medieval crossing at Nehringen was destroyed in 1505; plans for a new Trebel crossing were refused by Mecklenburg in 1780 and an iron swing bridge was shelved in 1896. The wooden bascule bridge, designed by royal building officer Westphal of Stralsund at a cost of 36,000 marks, opened on 19 June 1911. It was renewed in 1947, rebuilt to the historic model from 1983 to 1991, and again demolished and reconstructed in 2011, reopening in summer 2012.

The Trebel long marked the border between Mecklenburg and Vorpommern, and the bridge was financed jointly by the Pomeranian and Mecklenburg sides. For their efforts, the Prussian king awarded the Dargun district administrator Drechsler the Order of the Crown, 3rd class, and Gnoien's mayor Schmidt the Red Eagle Order, 4th class, in 1910.

The bridge carries the road between Nehringen and Klein Methling and is open to vehicles up to 2.5 tonnes since summer 2012. Its roadway is 3.50 metres wide, narrowing to two metres on both sides of the Trebel because of concrete elements. The bascule span measures seven metres.

The bridge was rebuilt twice after 1983: demolished and reconstructed to its historic design by 1991, then demolished again in 2011 for structural decay and rebuilt from the same plans. It reopened in summer 2012 for vehicles up to 2.5 tonnes.
