Vanha Porvoontie will reopen to traffic on 23 February 2026 – changes to traffic arrangements at the intersection of Sammaltie and Kyytitie
The concrete culvert found beneath Vanha Porvoontie has been demolished. A new stormwater line, district heating line and cable ducts have been installed at the roadway. The intersection area will reopen to vehicular traffic on 23 February 2026. Once the intersection is reopened, construction work at Sammaltie and Kyytitie can begin. District heating construction will also continue adjacent to the Vanha Porvoontie intersection.

District heating pipes will still be installed beneath Kyytitie at the intersection of Vanha Porvoontie and Kyytitie. Later in the spring, the intersection will be converted into a temporary roundabout for the duration of the construction work. Due to these phases, there will be significant changes to lane arrangements in the intersection area, and we will provide more information later. Please follow the traffic signs in the area and allow extra time for travel. The Vanha Porvoontie bus stop V6414 will be relocated approximately 20 metres to the west.
Intersection of Sammaltie/Kanervantie and Kyytitie
We will continue the installation of the gas pipeline at the intersection of Sammaltie/Kanervantie and Kyytitie. As a result, traffic will operate with one lane per direction or under traffic control using a single lane. During the work, the traffic lights at the intersection will be flashing, and general traffic rules and right-of-way regulations will apply. Work at the intersection will begin on 23 February 2026 and is expected to last approximately three weeks.
