Here is the intervention that will solve the problems with Mälarbron - "We think it is a one hundred percent solution"

To avoid the Mälar bridge, which swells on hot summer days, getting stuck in an open position, Södertälje municipality has for several years cooled down the bridge by spraying water on it.

A temporary solution that has been criticized for being resource-intensive and because the tanker used is blocking a lane.

But now the municipality hopes to have a more long-term solution.

The problems have been around for several years, why has the solution been delayed?

- It has been complicated, they have not known what to do properly, they have had different proposals but have not come to the conclusion that it works one hundred percent, says Halmat Amir, street engineer at Södertälje municipality.

Hear him talk about the procedure that will hopefully solve Mälarbron's problems in the video.

No security risk

But is it not a safety risk with interference with the bridge construction?

- Not what we know, we have not realized that it should affect the construction or function of the bridge, he says.
