Nockebybron, Swing bridge over Lake Mälaren in Bromma, Stockholm, Sweden

Nockebybron is a 450-metre swing bridge over Lake Mälaren linking Kärsön in Ekerö Municipality with Nockeby in Bromma, Stockholm. Its 80-metre central section rests on a round pier and turns 90 degrees; the free width is 24 metres and the clearance when closed is 12.5 metres. A staffed control tower stands by the bridge.

The current structure replaced an earlier version in 1973, significantly upgrading transportation infrastructure in Stockholm's western districts. This reconstruction improved connectivity between the shores and modernized crossing options for the surrounding communities.

The bridge is named after Nockeby in Bromma. Its opening is announced by horn signals, and the bridge keeper's tower is staffed from 1 May to 15 October. The keeper's house, Brostugan, built together with the 1787 bridge, has housed a restaurant since 1931.

The swing span opens on demand from 6:00 to 22:00, on the hour at Nockeby and on the half hour at Tappström, which it also controls remotely. The bridge stays closed to boats during weekday morning and afternoon rush hours, and in winter vessels must call to request an opening. The control tower is staffed from 1 May to 15 October.

The 80-metre central section pivots 90 degrees on a round pier; the operator's tower controlling it stands staffed from 1 May to 15 October and also remotely operates Tappströmsbron. The boundary between Stockholm and Ekerö municipalities runs just southwest of that tower.
