Marti was one of the contractors involved in the Astra Bridge, which is a bridge that can be installed over a motorway, such that roadworks can be carried out under the bridge while there is uninterrupted two lane traffic right above them. This type of construction was the first of its kind. The bridge has a modular design, its parts can be carried by regular trucks and it can be installed in a matter of days.
In 2020, Marti was accused that their handling of construction waste resulted in fish deaths in the Blausee since 2018. Marti denied the accusation, saying that what they did was allowed by the authorities and it was not the cause of the fish deaths. the case is pending in Swiss federal court.
