The renovation of Mäkelänkatu will begin in Vallila, Helsinki in October 2025.  During the project, approximately 1.3 kilometres of Mäkelänkatu between Kumpulantie and Hämeentie will be renovated. 

"Street construction in the inner city of Helsinki continues to be busy, as there are a lot of pipelines and infrastructure under the streets that are in need of renovation due to their age. We secured this most significant street work project in Helsinki in our order backlog,” says Jaakko Mäkelä, Business Director, Civil Engineering and Paving. 

The project related to the renovation of Mäkelänkatu was included in GRK Suomi Oy's order backlog upon signing the agreement. At the end of June 2025, GRK Suomi Oy’s order backlog amounted to EUR 397 million and GRK Group’s EUR to 789 million.   

Mäkelänkatu is one of the main roads in Helsinki 

During the project management, underground municipal technology, such as water and sewer pipes, district heating pipes and telecommunications cables, will be replaced on Mäkelänkatu. In addition, the surface structures and technical systems of the street, such as traffic lights, lighting and track engineering systems, will be replaced. Tramway rails will also be replaced in places. Cycling will separated from other traffic to its own lanes, with one-way bicycle lanes built south of Kumpulantie.  

In connection with the renovation, sections of the linden alley that are in poor condition will be replaced. The condition of the trees and their growing substrates has been carefully investigated. Approximately 100 trees will be removed from the section to be renovated and new seedlings will be planted in their place. 

"Mäkelänkatu is one of the busiest streets in Helsinki.  The renovation of Aleksis Kiven katu, which was due to be completed at the end of 2026, is currently under way near Mäkelänkatu. We have also been in charge of the renovation of Aleksis Kiven katu. We have succeeded in accelerating the schedule in order to complete the work there one year earlier than planned, by the end of 2025. We believe that this will contribute to reducing traffic jams on Mäkelänkatu during the project," says Mäkelä.
