http://openstreetmap.org/?lat=60.18933&lon=24.9642&zoom=18&layers=B000FTF Sturenkatu is in 40 km/h zone, the zone continues over the bridge. Teollisuuskatu is in 50 km/h zone that is signed with the city sign. Both zones also include large amount of other roads. IIRC the 50 km/h zone can be followed from that point many kilometers, and the 40 km/h zone extends tens of roads. There also might be other overlaps between them, or with other zones.
