Bällsta bridge, bridge between Sundbyberg and Mariehäll in Stockholm, Sweden

Bällsta bridge carries road traffic over Bällstaån between Central Sundbyberg and Mariehäll, on the boundary between Sundbyberg and Stockholm municipalities. The present bridge was built in 1936 and widened in a 1958 reconstruction. A parallel tram bridge for Tvärbanan runs along its southern side, opened in October 2013.

A wooden bridge was built at the narrowest point of Bällstaviken in 1690, linking Drottningholm Palace via Sundbyberg and Bromma to the ferry landing at Tyska botten. After 1787 a new route over bridges at Traneberg, Nockeby and Drottningholm replaced it. The present bridge was built in 1936 and widened in a 1958 reconstruction; a parallel tram bridge for Tvärbanan opened in October 2013.

The bridge is named after Bällstaån, the stream it crosses, which also marks the boundary between Sundbyberg and Stockholm municipalities. Since October 2013 the Tvärbanan tram stop Bällsta bro has stood at the bridge's eastern abutment on the Sundbyberg side, with about 1,200 boardings on an average winter weekday.

The bridge sits near train stations and bus stops, making it easy to reach by public transportation and a convenient walking or cycling distance from surrounding areas. It functions as a practical junction within the local transport network for residents and visitors moving through the neighborhood.

The bridge is named after the river it crosses, connecting infrastructure directly to the natural features of the area in a straightforward way. This simple naming reflects how local places often take their identity from their immediate geographic surroundings.
