Like every Finnish city outside of Greater Helsinki, all public transportation in Turku is serviced by diesel buses. Uudenmaankatu is one of the major trunk roads into the city center, and more than 30 bus routes service it. Back in 1988, I remember there being two bus operators, the city-owned TuKL and private Turun Liikenne, but as in other Finnish cities, transportation agencies have been significantly restructured since the 1990s.
