The southern part of the Bratislava ring road might be torn down. The new transport minister argues that the construction is not in line with the construction permit and the construction project.
The first reports of suspicions that there might have been a leak of dangerous substances emerged in mid-January 2019. In April 2019, the police charged one person and one company on suspicions that contaminated soil was used for the construction of the R7 highway in southern Bratislava, following a raid a few days before that.

The contractor for the D4-highway and R7-expressway project is Zero Bypass Limited.
