There were a total of 152 park and sports facility projects, 150 street projects and 18 other projects carried out in Helsinki in 2025.
Many key parks were improved
The multi-year renovation of Kaisaniemi Park progressed, with completed areas opened to the public during the year. The summer saw the opening of the entrance area of the Botanic Garden, which features impressive plantings, while the end of the year saw the opening of the Baana section adjacent to the park, running from the Kaisantunneli underpass to the north by the railway line. Meanwhile, the extensive renovation of Sibelius Park was completed with the opening of the eastern half. The western side of the park was completed in 2024.
In Sörnäinen, the renovation of Katri Vala Park was completed, and the park now features Finland's highest piece of climbing play equipment. In Vallila, the renovation of Vallilanpuisto Park was completed ahead of schedule.
In Pitäjänmäki, the Strömberg Park renovation project involved building a fishway for migratory fish in the Mätäjoki River. The fishway was opened at the end of October, and the following week a sea trout sighting was made in Konalanoja, upstream of Mätäjoki.
Helsinki’s first outdoor gyms for children were completed in Pukinmäki and Kontula to delight and keep children active. The gyms feature easy-to-use, lightweight equipment, which is especially suitable for school-age children.

The renovation of Mannerheimintie, the city's largest roadwork project to date, was completed well ahead of schedule in the autumn, as was the renovation of Aleksis Kiven katu. There were also several other roadwork projects that were completed ahead of schedule, including Kuninkaantammentie, as well as Orapihlajatie and Paatsamatie in Haaga. Furthermore, a one-kilometre section of the new Eastern Baana was completed between Tupasaarentie and Hiihtäjäntie – also one month ahead of schedule.
A pedestrian and cycling bridge over the Baana cycle path was completed between Lastenkodinkatu and the former Maria Hospital area. A ramp was also built from the Maria side of the bridge down to the Baana path. The bridge will be opened later. The project also included the construction of one-way cycle lanes on Mechelininkatu.
For the summer, the City implemented the Kallio summer streets project, which involved using temporary furniture and plantings to improve the walking conditions and comfort of several streets in Kallio and Alppiharju. The arrangements proved highly popular.
