What will the roadworks entail?
The renovation will include the following:
- Renewal of the old, about 100-year-old municipal technology. Municipal infrastructure refers, for example, to the water supply, district heating and cooling pipelines and electricity and telecommunication cables under the street. The new municipal infrastructure will last well into the future.
- Renewal of pavements, cycle lanes and roadways.
- Public transport improvements and tram network renewal, including 2.6 kilometres worth of new rails.
- The Mannerheimintien silta bridge across Baana between Kiasma and Pikkuparlamentti will be renewed.
- Additional loading and parking spaces will be added on the side streets of Mannerheimintie.
- Ruusankatu, Savilankatu and Sallinkatu will be converted into one-way streets.
- Hesperianpuisto will have a ramp and stairs demarcated by a natural stone retaining wall.
The work will affect traffic and generate noise and dust
The renovation work is estimated to begin in March 2023. The work is carried out in two stages, starting from the section between the Postikatu and Runeberginkatu streets and then moving on to the section between the Runeberginkatu and Reijolankatu streets.
The work will cause changes in the walking, cycling, public transport and motor vehicle routes. Traffic arrangements will be changed several times as the project progresses. Passageways will be marked as clearly as possible.
The construction work will also generate noise and dust even though every effort will be made to prevent it. The aim is to have the renovation completed by the end of 2025.
