The technical systems of the road tunnel leading to the Port of Vuosaari in Helsinki are being replaced as they are reaching the end of their life cycle. The tunnel will be closed to traffic for the duration of the renovation at the end of 2025.
The tunnel’s alternative route has been upgraded and will be tested from 16 June at 22:00 to 18 June at 22:00, when the tunnel will be closed and traffic will be diverted to the emergency route.
New traffic cameras and two counting points have been installed along the emergency route to monitor travel times and traffic flow, among other things. Read more: https://www.fintraffic.fi/en/news/renovation-vuosaari-road-tunnel-technical-systems-improvements-tunnels-alternative-route
