Temporary traffic arrangements on Lämpömiehenkuja and Metallimiehenkuja
The building planned for 6–8 Metallimiehenkuja will be connected to HSY water and sewer network at the intersection of Otaniementie and Lämpömiehenkuja.
Due to connection work, traffic arrangements on Lämpömiehenkuja will change, and the road will become one-way from Metallimiehenkuja towards Otaniementie.
The new arrangements will be implemented on Monday, November 24, 2025. The work is expected to last approximately two weeks, after which the traffic arrangements will return to normal. During construction traffic will join from the construction site to Otaniementie, and a traffic controller will manage other traffic.
Pedestrians and drivers are encouraged to pay special attention to heavy vehicles near the construction site and and follow the temporary traffic arrangements and guidance.
