In May 2020, on the occasion of the City of Zagreb Day, Bandić opened the reconstructed Remetinec Roundabout, a joint project of the City and the Croatian Government. Construction of the Sljeme cable car, which began in early 2019 and was described by Bandić as one of his biggest projects, faced delays and increased costs. Bandić was expected to open it in March 2021. In November 2020, an anonymous whistleblower published a 7-hour long video that presents a detailed analysis and a large set of evidence to demonstrate how Bandic, the city officials and several private companies artificially bloated up the costs of the project by several hundred million kunas.
