The construction of the Jokeri Light Rail will be affecting traffic in the Helsinki metropolitan area in the coming years. Temporary traffic arrangements that change pedestrian, cycling, motor traffic and public transport routes during construction will be implemented in the vicinity of worksites.

Summer brings changes to the opening times of the services of the cities of Helsinki, Espoo, Vantaa and Kauniainen. During the holiday period libraries and health services, for example, operate on a reduced schedule. In transport, there are some bus stop changes and the routes of some buses change with the switch to summer transport.
