The Magere Brug is the last wooden double-leaf drawbridge left on the Amstel inside the city centre. A narrow bridge has crossed here since the 1690s, and magere means thin: the first one was too tight for two people to pass. The two halves of the deck still lift for boats too tall to go under, and there is no timetable for it. After dark the outline is picked out in small lamps.
The one you walk on dates only from 1934. Piet Kramer of the city's bridge department built it after a temporary iron bridge had served for five years, and the council chose to rebuild in wood rather than modernise. The river is the reason to stand here. The Amstel is far wider than any canal in the ring, and it still works, carrying water off the polders south of the city and through the centre to the IJ. The lock gates a short way upstream, built in 1673, control that flow, and river water was once let through them at night to rinse the canals.
