The Magere Brug is a bridge over the river Amstel in Amsterdam, Netherlands. It connects the banks of the river at Kerkstraat, between the Keizersgracht and Prinsengracht.
The central section of the Magere Brug is a bascule bridge made of white-painted wood. The present bridge was built in 1934. The first bridge at this site was built in 1691 as Kerkstraatbrug and had 13 arches. Because this bridge was very narrow, the locals called it magere brug, which literally means "skinny bridge". In 1871 the state of the bridge had deteriorated so much, it was demolished and replaced by a nine-arched wooden bridge. Half a century later, this bridge also needed to be replaced. Architect Piet Kramer made several designs for a steel and stone bridge, but the city decided to replace it with a new bridge that looked the same as the previous, only slightly bigger. In 1934, that bridge was demolished, and replaced by a redesign made by Piet Kramer. The last major renovation was in 1969. Until 1994, the bridge was opened by hand, but is now operated automatically.
Use of the bridge has been limited to pedestrians and cyclists since 2003.
