Worth knowing

Länsiväylä and the ring roads

The city's own traffic review names the Espoo–Helsinki motorway (Länsiväylä) and the Kehä ring roads as Espoo's largest sources of traffic noise and air pollution, with volumes still rising near Matinkylä.

Updated now. These are modelled estimates for the area around Espoo, not readings from a street monitor — air right beside a busy road can be worse than the area-wide picture.
