The bus will not run via Eino Leinon katu and Toivonkatu. Instead, it will run via Topeliuksenkatu, Runeberginkatu and Helsinginkatu. The "Ratikkamuseo" (H1328 and H1329) and "Töölön kisahalli" (H2064 and H2065) stops will not be served.
The bus will serve the following stops along the diversion route: "Töölön kirjasto" (H1315 and H1346, Töölö Library), "Töölöntori" (H1331 and H1311) and "Ooppera" (H2062 and H2185).
The diversion is expected to be in place until the end of 2024. It is due to excavation work on Toivonkatu.
