Street traffic

The Helsinki Region Environmental Services Authority (HSY) renovates the water-supply network at Mechelininkatu and Porkkalankatu in 2018–2019 and increases the capacity of the water mains supply network in Ruoholahti. In particular, working at the Mechelininkatu and Porkkalankatu intersection in May–August 2018 will bring about unusual traffic arrangements and hinder the traffic to the West Harbour.

HSY is working on Eerikinkatu, Köydenpunojankatu, Mechelininkatu, and Porkkalankatu. Construction work began in March 2018 and will be completed in August 2019. The contractor is Pohjola Rakennus Oy Infra.

Construction work will affect both traffic and the water supply.

Construction work has been divided into seven different phases (see the map at the end of the text). The working phases of the most critical areas of our service are scheduled for the summer season when there is less traffic. HSY will give you more detailed information on the timetables and the impact that the vari-ous construction phases will have on traffic on the Helsinki City Temporary Traffic Arrangements site (only in Finnish).
