The bus will no longer run via Työpajankatu and Tynnyrintekijänkatu and will no longer serve the "Suvilahti" (H2518 and H2519), "Tynnyrintekijänkatu" (H3000 and H3001) and "Kalasatama (M)" (H3004 and H3005) stops.
The change is made to facilitate interchanges between bus 55 and the Metro and improve transport links to Redi.
