Jann-Berghaus-Brücke, Bascule bridge in Leer, Germany.

The Jann-Berghaus-Brücke is a bascule bridge on the B 436 between Leerort and Bingum, carrying the road over the Ems. It is 464 metres long, with 206 metres of approach on the west side and 204 on the east up to the bascule section, which is 63 metres long; the roadway is 7 metres wide between 12-metre railings.

A swing bridge built in 1948–1950 stood here and was the world's largest of its kind when opened; it was demolished in 1991 due to structural decay. The current bascule bridge was built from 1989 to 1991 and opened on 17 May 1991 at a cost of 40.1 million D-Mark. Between 2008 and 2010 the navigable opening was widened from 40 to about 56 metres for Meyer Werft ship transfers.

The bridge is named after Jann Berghaus (1870–1954), who was president of the Ostfriesische Landschaft and campaigned for regional interests. The name was already carried by the second bridge on this site, opened in 1950.

The crossing links both sides of the region and provides access for cars and pedestrians across the Ems. Since the bridge regularly opens for ship passage, allow extra time when traveling during busy shipping periods.

The bascule span is 63 metres long; when it opens, 45 metres tilt up while 15 metres descend into a chamber beneath the roadway. The 2008–2010 widening to about 56 metres let Meyer Werft's large newbuilds pass; in September 2008 the Celebrity Solstice moved past the construction site.
