Here we want to present new findings of Nyctalus noctula, Myotis myotis and Myotis daubentonii roosts in bridges in Slovakia. Annual observations from one bridge in Nitra showed high use of this habitat type. Also incidental findings from five other localities are presented. In Nitra 1533 records of N. noctula were obtained during 28 surveys. Noctules used the bridge drainpipes and other crevices all year round except the summer months. The highest number was recorded in November (164 individuals) when groups of up to 60 individuals were present. In autumn mating aggregations accumulated (3–9 individuals). The bridge was also used by solitary M. myotis males (64 records). In autumn mating groups of 2–3 M. myotis were also present. Big aggregations of N. noctula (maximum 457 individuals) were also found in a bridge in Ružomberok. In addition, two other localities with bridge roosts of M. daubentonii were found.
