It's just fun to sit in your front garden and watch the boats go by. In the old days there would be a 'clog' where the skippers would donate a few coins for the bridgekeeper. I haven't noticed if this is still the custom in 2005 but it was in the 80s.
The bridge is the center of the village, over the river Vecht, connecting the old northern part with the newer southern part.
During season, the bridge opens several times in an hour to let boats (mostly yachts) pass by. The bridge is electric and cost 1 million guilders some 20 years ago. When I lived there, it was still mechanical and made a lot of noise which was actually the whole charm of it.
