Sundsvall Bridge, Motorway bridge in Sundsvall Municipality, Sweden.

Sundsvall Bridge is a 2,109-metre road bridge across Sundsvall Bay, carrying the E4 motorway on a straight deck. Its deck rests on three pale grey concrete piers, from which angled supports splay upward to form triangular brackets. The bridge opened to traffic on 18 December 2014.

Construction started in April 2012 using innovative foundation techniques with load-bearing steel sheet piles to handle the challenging bay conditions. The project reached completion in 2014, significantly improving connections across the bay.

The name Sundsvallsbron was given at a naming ceremony on 15 September 2013, not derived from the architects' concept. The 1995 competition-winning proposal by the Danish KRAM group was called Dubbelkrum, meaning double bend, because the roadway bends twice. The bridge was named after the bay and town it crosses.

The bridge carries the E4 motorway over the Sundsvall Bay with a toll since 1 February 2015: SEK 9 for cars, light trucks and buses, SEK 20 for heavy trucks. It shortened the E4 route around the bay by 2.3 km and cuts driving time by at least 5 minutes, more at rush hour. Traffic fell from about 13,000 to 6,000 vehicles a day after the toll began, mainly regional commuters.

On Lucia Day 2014, 10,500 people walked across the bridge in what was reported as the world's longest light train, a record set before the bridge had even been open a year. The name Sundsvallsbron was formally given at a ceremony on 15 September 2013.
