A serious accident happened in Umeå, Sweden, on Tuesday morning.

An accident occurred on a bridge under construction across the Umeå River, and some of the bridge structures collapsed down the Umeå River.

The Swedish broadcaster SVT, among others, reported the bridge accident.

Gerhard Barrestål, project manager at the Swedish Transport Agency, told SVT that it was one bridge beam that failed during the installation work.

The support that supported the structure collapsed and was left hanging on the wires, partially submerged in the river.

One construction worker was slightly injured in the accident.

The Finnish Transport Agency also warned people boating and moving downstream of the Umeå River that even large parts of the bridge's building might drift with the flow and cause dangerous situations.

According to Barrestål, there is no immediate risk that more parts of the bridge will collapse into the water at the bridge site.

The bridge is being built by the Finnish construction group GRK, which has operations in Finland, Sweden and Estonia.

There are also Finnish workers on the bridge site.

The bridge is scheduled to become 530 meters long and is part of the new E12 highway bypassing Umeå.

The bridge will have three lanes, two to the north and one to the south, as well as a 3.5 meter wide bike lane.

The estimated cost of the bridge was SEK 442 million (EUR 42.4 million).

The bridge was scheduled for completion in the fall of 2021, but as a result of the accident, the schedule is likely to take a backseat.
