The bridge over Lahdenväylä will be closed to traffic from 12 August for the construction of the Jokeri light rail line. Trunk route 550 will be diverted to run via Viikintie to Hernepellontie, from where it will resume its normal route along Maaherrantie. The bus will not serve the bus stops along the diversion route. The bridge is expected to be reopened to traffic in spring 2020.
